Menace kick ass idea for a new forum..... Way to go :luxhello:

Not my idea. I just do what the people like. It is a good idea and will be great when there are tons on how-to's in here. :cyclist:

[HSGear]

Just don't do the mod! I had it on a bike I bought - what crap! Sounded like shit and made the bike run horribly!

[AirportFF]

Sounds fine to me and works even better :happy:

[Ghost_Rider]

Good idea to have this section!

The holesaw mod is very cheap and make my bike runs a lot better. I hv to agree that I didn't really like the sound, but I never regret to have done it though :happy2:
Great pictures & instruction, Menace!

[UncleFestes]

I didn't like the sound so I cut all my goodiesout and insetrted 1 3/4 'x 18 inch long straight pipes from Pepboys. Advanced and others have the same pipe the slip on end wil fit tight in the Holesaw cutout.. the other end wedges in the tapered end.. Just put a long 3/16 screw in the botton of both pipes. that way the police that don't like to bend over and try to shove their nightstick up it won't be able to.. It really sounds great with the straights...for about $12. + tools.. now you can run the hole saw all the way because the other to pipe baffles are on the side and the saw is way to short to cut the complete baffle out so I used a long chisel and hammer and cut the welds. you must take the mufflers off and drive everything to the exhaust end. I still had to use my dremal to cut some things smaller to get it all Out. what a job but well worth it... The square slot is so the crossover can still work a little the tab is just bent in...at a 75 degree angle.

[Galager]

Did it on my bike and I think it runs better than before. Did you adjust the air/fuel mixture? Once I made that adjustment, I had better throttle response. As for the sound, it sure sounds better than the stock pipes, it at least sounds like a motorcycle now and not a sewing machine! Loud enough for me, in fact, I don't want it any louder. IMO - a great mod for the money ($20 for a holesaw).

[Rheopipo]

I will give it another crack on saturday... tried it once but the holsaw that I had broke! so I am going at it again thanks to a big ass drill (with power hammer and every gadget imaginable) and villawisco (the noob) we met by chance in the Island I was a little aprehensive because I never heard a spirit with this mod but after hearing his spirit it is a go and he gave me another holesaw, so maybe I will have a good sound that will go with the good looks.

Don't use the drill in hammer mode. You will bend the holesaw

Damn.... I wanted to wack that :grin:

[AirportFF]

Sorry. The hammer feature is only suppose to be used for carbide masonary bits.

When you do it, don't put pressure on the holesaw. That will only dull it faster and it actually cuts slower. You'll feel a "sweet spot" as far as the pressure goes, that's where you'll be cutting the best. A little cutting oil won't hurt either.

I will do just that.

Dont' listen to him! Leave it in hammer mode! Dont forget your ear plugs and dont hold the drill too tight!:laugh2:

I'm surprised that no one has mentioned "the blow torch" yet.:no:

Make sure you rush through it Rheo, and if the drill brakes your arm, post a pic of you in the cast. :jester:

Really, take your time, use lube, and don't push too hard. (We are talking about the holesaw mod, right?) Maybe this should be in Susan's Sidecar...:laugh4:

M@

[AirportFF]

Push too hard, bind the saw, drill spins violently, wrist twists and possibly breaks, possible fucked up exhaust, possible fucked up rear wheel. :wink_2:


Some holesaws are hairy things. I've used up to 8" saws and they can tear your arm off if they get hung up. The best thing to always remember when using one is to let the tool do the work, you are only there to guide it.

And if that doesn't work, get a blowtorch!!! :happy:

[Rheopipo]

Hole Saw........ .............................................$20.00 (actually free) Check
Super drill wiht power hammer.......................$200 (actually loaned)Check
Blowtorch (just in case)..................................$$$$$..(Ok I dont have one)

Hearing you bike breathe louder.........Priceless!

There are some mods that money can buy for everything else... Shadowriders and Co..

[Rheopipo]

This fucking rain wont stop... if I do the mod tomorrow I will get wet...

[M@Man]

Don't be such a baby, electric drills love the rain, just like bathtubs and toasters! :devil:

When I use to do environmental construction years ago. We would cut gasoline piping with a sawzall. That made for some tense moments. Oh, and there was the time I set a empty 40k underground diesel tank on fire from the sparks coming off the saw while cutting it open. That was fun :wink_2:

[UncleFestes]

Yes please don't use hammer MODE.. also why can't you take the bike in the Kitchen out of the Rain. and do the mod there.. I bought some cutting oil from Home Depot a qt for about 2 bucks well worth it.. Use a drill with speed control or one thatturns about 600 rpm and like they say take it Slooow...and easy. Good Luck ..

[Rheopipo]

Man if I took the bike to the kitchen I would be divorced the next day! I made it, super easy and it sounds great! used the oil as sugested and it was very easy it took me 15 minutes and done! It still raining but I was riding all weekend on the rain makin noise!!! thanks for the help and comments I would post picture but have to ask for the camera, besides it is the same bike with bigger... pipe holes??? Got to work!

[UncleFestes]

Great !! glad you like it.. Have Fun...

Congrats, Rheo! :thumb:

Ride hard, Ride LOUD! :wink_2:

[Cactus Jack]

This mod requires a stage 1 carb rejet, correct?

[HSGear]

Jack,

Unless you put in a high-perf air filter like a K+N or Uni Filter you should be able to just open the mix screws a bit and be fine without the rejet. Most pipes don't need a rejet if the head pipes are the standard 1.75" size your bike came packaged with and you use the stock air filter.

[chandlerk]

Just did this easy mod yesterday and it KICKS ASS! Now my girlfriend can't punk me at stoplights with her V&H pipes. Bwahahahaha!!!!

I haven't messed with the mixture screws. I took the bike out and test drove it. It doesn't pop a bit even on hard decel down steep hills. Rode it over 75 miles today with no problems, either.

Should I just leave well enough alone?

[airbrush addict]

OK, I plan on doing the same mod. but, how many turns do you make on the mixture screws, which direction? How do you know when to stop??? Great forum!!! This is my first post so go ahead and say it "Fuck off noob"!!!!

Look forward to your response....

Fuckoff NOOB to both of us I guess HAHA!

I didn't touch the mix screws yet since there's no popping (lean condition indication) while riding. The forum with the holesaw mod here on Shadowriders has instructions for adjusting the screws if you want to do so.

[airbrush addict]

Thanks I guess I'll read all of the directions

[jrod1970]

here i'll help.....ahem..fuck off noobs!!!!!!!!!!!!!!!!!!:flipa: :flipa: :flipa: :flipa: :flipa: welcome to shadowriders!!!:crazy3:

[airbrush addict]

Thanks, I feel welcomed now. I looked thru the previous posts and cannot find anything on adjusting the mixture screws.

[jrod1970]

try the search button, you got to drill them out, t think, i didnt do it on my bike,wass already done

Great Dude Just Bought A New Sabre 1100 And Was Asking This Question But Also Want To What Jetting Is Best

[Titanium2006]

Sounds like junk, Save the pennies and get some real pipes.

[pbus]

For what it's worth, did this to my 600 but didn't like the sound. It was too harsh. Got a set of 4" mini baffles from J&P cycles (3.99 each) and bent the interior baffle portions down so they would be more straight through. Had a stage one jet kit put in and it is fine. It has a little better throttle response and a nice but not to loud, mellow tone to it.

[dirtwarrior]

I drilled out the resonator then chisled out the screen a little further up, but there is some more metal just behind the screen. I can get an extension for my hole saw and drill it out. Is this recommended?

[crawdad]

will that same method work on an 85 vt 1100

[shadow_walker_88]

anyone have a sound clip?

found one kinda rough sound'n file tho

Yea you can cut out the baffle on a VLX also...

[UncleFestes]

But I thought mine sounded Sick just cutting the end baffles and Briggs mufflers out.. so I cut mine all the way through. Cut a 2" hole saw and put a 8" long 2" pipe in the middle then you can cut the other pipes that are 6" long and will be split in half with the hole saw... then I inserted a 2' Pipe the was 18' long up tight into the tapered part of the front. then bolted the back part underneath the stock muffler section. I sounded a lot better due to the sound being deeper and more pronounced.. I ran them straight and didn't have a noise problem... Good luck

Has anyone done the hole saw mod on the new C2?? If so, did u need to rejet after. Regards

[Spirit_C2]

Ive done the hole saw mod on the C2, so has gulf coast kid and a few others, I didnt need to rejet you shouldnt either, maybe a carb adjustment, mine is fine so far, If your poppin on the down rev or notice anything else from before the mod then you shuld probally adjust the carb

[craigv318]

Thanks for the advice Spirit C2.
Still a bit affraid to do mob. (yes, im a soft cock) But it will save me heaps ($700) on new pipes.... If it doesnt work, i can always tack weld it back in i guess.. Or just buy pipes...
How did the bike sound after the Hole saw?? Much louder or did you notice any improvement on HP..

I did a holesaw mod on mine it sounded better. If you want to go a little further on the mod take the muflers off and beat the rest of the baffles out with a pipe and hammer. It will sound great.

[benjam02]

Has any one done the hole saw mod on a 1987 vt700c ? If so how does it sound?

[PeeWee]

Has anyone cut all the baffles out? I cut my end ones out but was planning on getting an extension and gutting them completely, they'll be pretty much a drag pipe afterwards.

[Raymo]

Did the holesaw mod on mine a couple of months ago. Sounded much better. But.... I should have V&H Straightshots on by next Tuesday or Wednesday. Fuck it, it's only money!

[Ears]

Finally did the holesaw mod, after procrastinating for about 8 months, on my new 750c2...took about 5 minutes with a hammer drill and a bi-metal holesaw...should have done it months ago...sounds great

[dirtwarrior]

Glad you like it

[YO MUDA]

I did mine when I first got it. Sounded better than stock. Then went lookin for some new pipes, shit priceeee. Hooked up with Oomp on TSW and he made me some pipes. My design, his talent. Better lookin and sounding. A lot less $$, put em on in less than 30 min. I love em. See my gallery for pics.

[PeeWee]

I completely gutted mine today.....a 16 inch holesaw extension, a 2 in holesaw and bodda-bing....they sound better than my brothers Cobra's. They have a MUCH deeper tone. I think the expanded part of the exaust "silencer" is what gives it the tone. No popping on decel, no flat spots accelerating and the plugs have a nice pretty "caramel" color to them. I done plug chops at a 1/4, 1/2. 3/4, and wide open throttle. the jetting is perfect......when the temps heat up though, i'll have to make some alterations. The big key....i saved myself about 4 bills on pipes!!!:jamming:

[Jwilkspirit]

Hi everyone, NOOB here, I thought I should just let you all know. Just did the holesaw mod yesterday and I highly recommend it to anyone who is seeking an improvement in sound. The sound amazing for about $20. You can't beat that price, and it really sounds like aftermarket pipes, I am turning heads everywhere now because my bike doesn't sound like a weed wacker.

Bullshit

[Jwilkspirit]

What bullshit

[Jwilkspirit]

Well it sounds good enough to me, so that I can start customizing it finally without having to worry about forking over $400+ to get an exhaust system. That was my biggest holdback, I didn't want to customize (i.e. lowered rear, side license plate) and have a custom looking moped:thumbsdow lol!

It makes a big improvement in sound, I just couldnt stand the looks anymore so I made my own.

[Jwilkspirit]

That looks really good! Are those slip ons or did you adapt a pipe?

[SS rider]

I had the local exhaust shop swedge a pipe down from the headpipe O.D. size to the inside diameter of some truck exhaust tips. I have a thread about it around here somewhere. Ill see if I can find it.

I did the hole saw mod it took about 10-15 minutes sounds awesome! also drilled my mixture screws, adjusted em to 3 and 3 1/4 no more popping. used 90w gear oil on the hole saw every lil while it was a 2 1/8" hole saw then i yanked the guts out with a pair of vice grips.

[87shadowman]

Whats goin on people just bought a sweet 87 last year and man did I get lucky but being a big guy I don't know if there is anything I can do to make it more comfortable to ride? maybe handlebars? forward controls any help would be appreciated and if there is something maybe a hyperlink or two?

Thanks,

[firefighter212]

check out my pipes that you can make on your own.guys say you can get the pipes from napa but yet to go there.look up my post and will give a brief descripition of what i done as well as others on this site.be aware for there are a patricular few on this site that think that this is a"hacked" up way of doing your pipes but it`s just as effective as spending 400 to 500 dollars for the same sound and performance you will get from aftermarket pipes.

[BallsackMcgee]

Did this the other day and just wanted to add..... Sounds like total ass! Only time it sounds half way decent is when full throttle otherwise the bike sounds like a damn 4 wheeler.

Only plus I guess is that cars can hear me coming up on them a little sooner but damn cant wait to make new pipes! Its almost shamefull...

[OffshoreKing]

Just did the holesaw mod to my stock exhaust .. blah... Not that great of a sound but did improve my throttle reaction. Sound is louder than stock without question but this is only a temporary fix till i get a new exhaust system.

[baja_racer]

Did this mod yesterday......not disappointed at all. No popping at decel, very easy to do.

[baja_racer]

Ok,
After a long ride I started to get the popping sounds, found the air/fuel mixture screws and adjusted both............that's even easier than the hole saw mod.

[cuttingman423]

hope someone can help me and have answer to my question.
i have a 1995 VT100C and it came from New Hampshire and is jetted and set for high elavation and it runs rich now that its in Pennsylvania evalavation about 1500 ft above sea level and Average in New Hampshire is 6000 ft above sea level from what i could find on the internet i feel its set for the high elavation since i only get 35 MPG and a friend of mine has the same bike and gets 46 MPG . Since i dont understand and have knowledge of jetting carbs my question is if i mod my pipes to make them full open drag pipes will the setting they are at for high elavation be close or just right for drag pipes or will it be set way to much the wrong way. I hope someone here as the knowledge of how jetts work for different elavations and can help me here cause if i mod the exhaust and it wont run right or at all i dont have the funds to pay my local honda dealer to get it right so i can ride it.
the mod i want to do is take mufflers off completely and weld on straight pipe right on the header pipes fully open no back pressure. then wrap with exhaust fiber that you can get at autozone less polishing the better rather ride it then spend hours polishing just to take it out and get it crapped up

[SlapDrum]

I'm in Diamond Bar Ca. Anybody nearby do this? I'd like to come hear the bike then do it to mine. Just thought if anybody was close enough I'd sneak a listen first. Thanks, Chris

I'm guessing the Hole Saw has already been done??? :jamming:

[firefighter212]

from the pics,it looks like they have been removed but not with a hole saw.Looks as if they drilled multiple holes and played connect the dots with a sawsall.same outcome but looks better with all of it out of there.

I'm thinking a little Hole Saw clean up is in order and just wanted to make sure I wasn't missing something.

You'd have to kiss a girl to know that, and since your a WOW geek, we all know that didn't happen.

Now FUCKOFFSPAMMER!

[dwilliamsfaq]

Did the mod last night, but an '08 model will not take the 2 1/4" holesaw. I used a 2" hole saw and it was a tight fit because of the pipe flair on the new model, and there is only one layer of metal to cut thru. Have only ridden down my street and back and it sounded good, but will not really be able to tell until I get to ride it to work again.

[b10e]

alright i justdd the mod. an now i have smoke coming out of the headers. isd tat normal? i didnt put any gaskets on..should i have done that? wats goin on? yea i know fuck off noob whatever whatever answer my question.

Your Fucked Noob!!

I'm not sure might just bee left over shit from drilling, Somebody will pipe in I'm sure

[dwilliamsfaq]

Did you remove the exhaust to do this mod? If so you will need to put all of the gaskets back in, and make sure all of the crossover tubes are connected again. This mod it setup so you dont have to remove the pipes.... hence the holesaw and drill. The other thing to look at is did you run the saw all the way up into the pipes? If so you could have damaged the internal sleeve of the pipe, the chrome is just a casing and is not sealed all the way. This is why our pipes dont take on the purple/blue tone that a nice set of custom pipes get after they are run in.

[b10e]

i did the mod but i hear its really bad for the valves not to have any baffls or anything. i like the way it sounds but now im scared im gonna fuck up the engine. what can i do to protect it now tha i have no baffles? btw i did the mod on my vance & hines not my stock exhaust.

[cjones]

holy fuck really sell your bike now or its junk ill give you 1500 for it now

[b10e]

alright so what the fuck..?? that doesnt answer my question. did i seriously fuck up by riding it without baffles? should i not ride i without baffles? what?

[firefighter212]

Hey Noob,3/4 the guys on here have ran or are running without Baffles.If that was the case you would see a tread on replacing valves.NOFUCKOFFNOOBWITHNOBAFFLES and welcome to the site and beware you will get flamed for this but stick it out.

[b10e]

right on man. thanks, that fucker scared the shit out of me. i think i am gonna throw some baffles in my pipes anyway though. yea the n00b bullshit doesnt bother me, i think its funny. theres a lot of internet tough guys on here for sure. its a good site though, lots of good riders who know what theyre talking about. thanks again man.

[rugby66x]

So tmr morning im planning on doing this and ive been reading a lot about the airfuel mixture screws on here and just wondering where those are and if i could get a quick how to on how to mess with them once the mod is done if i even have to

thx

noob in need

[malern28us]

I just got done doing the mod. The sound will do till i decide where to go from here. Besides, The wife said she likes it more since it is louder... :bed fart:

[cjones]

fuck you find it yourself give you a hint it starts with s and ends in earch

[Born2Boop]

Did the mod over the 4th of July weekend - ok ok, I asked Dad for help :cool4: he had the tools - and I'm thrilled with the results. Had a nice 2 hr ride home.

I didn't mess with any of the screws, etc. Only thing I noticed was a 2 1/8 in hole saw was not getting into my pipes. Had to use the 2inch. Looks like a couple of other guys did the same but now it has me wondering how much the pipe sizes vary from yr to yr, or even from bike to bike. I didn't notice before doing this that the internal welding seemed sloppy inside, like there was extra material that hardened there. The saw shaved it down, but I thought it was strange.

oh well. Here's to not sounding like a pansy next to the bf's bike anymore! :happy2:

<TABLE border=0 cellSpacing=1 borderColor=#c0c0c0 width="80%"><TBODY><TR><TD>When making modifications to the stock exhaust such as punching or drilling holes, or after adding an aftermarket exhaust, it may become necessary to make some adjustments to the pilot jet (idle circuit) air mixture screws to eliminate the "Rice Krispies", the crackling and popping you get when decelerating. Here's how it's done.
Oh, and by the way, just for RockRabbit, the left side screw is for the rear cylinder (see the cylinder intake port and the boot from the left carb running down onto it?), and the right side screw is for the front cylinder (look at the intake boot, same as the left side.).
UPDATE! Please see the Exhaust Mods & Mixture Screw Update (http://whytlash.powweb.com/update.htm).

I originally just raised my idle with the idle screw (the black knob on the left side of your carb in front of the throttle wheel that you cable run to from the throttle on the handlebar), until I could figure out where the air mixture screw was.

Forward of it is a brass screw that is the drain screw for that carb. If you turn that screw counterclockwise to unscrew it, fuel will start dribbling out of the little nipple right below it.

SO DON'T DO THAT, I'M JUST POINTING IT OUT.

Anyway, I got a small drill bit, about 1/16" (I think), and carefully drilled a hole in the center of the plug. Don't push too hard or it will go through the plug and hit the screw behind it. Use just a little pressure. After drilling, get a sheet metal screw that has threads a little bigger than the hole you just drilled and start to screw it in the hole. When it gets tight, get a pair of pliers and grab hold of the screw (vice-grips would work good here) and carefully tug on the screw. Eventually the screw with the plug attached to it will pop out. Look into the hole the plug came out of.
There you will see the holy grail, the brass AIR MIXTURE SCREW!

Use the other allen in your kit to remove these, or a ratchet with a 10 mm socket. The heads are about 1/2". You can't miss them.
Then, look behind the airbox on the forward side near the top. There is a steel band that is tightened around the tube that leads from the airbox in the top of the carbs. Loosen the screw on the band. Now just pull the airbox toward you and down and out she'll come.

These screws adjust the amount of fuel that the pilot jets (idle jets) squirt into the carbs. Carefully screw each one in until it lightly seats closed, and count the number of turns. This will tell you the number of turns each was open and give you a new starting point for adjustment. Now carefully screw out (open) each one to 3 1/4 turns open (1 full turn beyond the factory setting).
If you're picky, like me, take each plug you removed and drill the hole just large enough for the tip of your little tiny screwdriver to get through, then reinsert the plugs. Or, you can stick a little dab of silicone sealant in each hole. It sets up, hold the screw, and comes out easy if you want to "fiddle" later on.
That's all there is to it! It's actually pretty simple, just need someone to tell you where stuff is. And pictures are always helpful.
If you have any more questions about this, just let me know (blacktop@sa750.com).

Thanks for your comments. I talked with her again and she said that she just did wanted to make sure that i am not hurt if i told someone because it was very important information.

Thanks again

I have read some guys not being able to get 2 1/8" hole saw in, I tried last night too and found that the 2 1/8" one is the exact size of the exhaust hole on my 2007 750 C2. So, I will have to go down to a 2" as well... what year were other people having trouble getting the 2 1/8" to fit?

Oh, and FUCK OFF ME (Noob)!!!

Just took my 1st baby steps as a noob...

Removed the reflectors from the radiator. Total 1 minute and no cost!

Removed the Honda sticker from the rear fender. Total 10 minutes and no cost!!
Damn glue they use is a bitch to remove.!!!

And removed the resonators from my stock exhaust. Total 5 minutes and no cost!!!!!!! woot

Absolutely LOVE the way she sounds now!!!!! Can't wait for my buddy with his 2010 (tinny sewing machine sounding $11k) Triumph Thruxton to HEAR HER :grin:

Today's the day hopefully. On average it sounds like most are getting away without having to adjust jets? This is my only hesitation. Don't want to fiddle too much with engine tuning. How many are having backfiring/performance issues?

How many are having backfiring/performance issues? do it dude, you won't be sorry. You won't have to rejet for this mod, you might have to adjust the a/f screws but that takes a small flat head and one min on each side. Alot of people don't have to even do that. it only needs to be done if you get alot of backfire on decel.

OK, you want it to flow a little better still? see those screens in there...you can try to cut it out but thats a pain in the ass. take rebar or a long pipe and punch holes it the screens. start in the middle and punch a big ass hole the go to the outside edges and do the same thing. it'll be a little louder and flow a little better.

[SolCalSpark]

Thanks bros for all the great info.

Really need a set of forward controls first!!!

Looking to do the Bean Box Mod after that and then the 4 deg. timing mod.

That will cover everything from oil change to tune-up and carb work!!!

Got a part # for the spark plugs JayT???

[Mz Green Eyes]

Thank you Menace that gives a even pic descrip for pipe mod than I found. I will be doing this week!!!!!

[MPeG]

I just did it on my (02) Spirit 750 last week. Worked great, no A/F tuning needed, overall worth doing to give it a little grunt but it doesn't sound like a performance exhaust by any means..... when going 60mph or so the exhaust actually sounds a little retarded.

I would recommend this mod though. Its free (was for me since I didn't have to buy anything to do it). I used a Dewalt XPS drill and WD-40 with a ridgid bi-metal bit. I went slow and it took less than 1min per a pipe.

[Mz Green Eyes]

Hey Mpeg congrats. It took a minute for my engine to blow out build up but it sounds better as I ride it. Also there is a second mod if you want it to sound louder but I was happy with the improvement. :jamming:

[MPeG]

Thanks bro!

[MotorDonkey]

I did this mod based on the good reviews here and it sounds ok I guess. Except while holding a steady speed.... Sounds like a dry fart! I kinda wish I hadn't done it now.
Oh well, live and learn I guess.

[MPeG]

^^^^ Yea, for a freebie its a great mod. When my wife was riding with me she said the bike sounds really odd when holding a steady pace (much like you're stating). I am looking forward to getting a V&H exhaust when money prevails..... but for now this is a great mod to hold you over.

[Shadow Bagger]

Man if I took the bike to the kitchen I would be divorced the next day! I made it, super easy and it sounds great! used the oil as sugested and it was very easy it took me 15 minutes and done! It still raining but I was riding all weekend on the rain makin noise!!! thanks for the help and comments I would post picture but have to ask for the camera, besides it is the same bike with bigger... pipe holes??? Got to work!


Divorce is a great sacrafice when it comes to the bike

Any y'all ever bother to just drill a few holes around the central "butthole" of the resonator?

:spank me
In either this forum, or another, can't remember, I think there was someone that did that, and mentioned that you do get better sound than stock, but I don't know if it would be as loud or deep, as fully removing the resonator?
I think some have also wondered about getting a long drill bit and drilling straight up the center with a 1 inch bit, or whatever diameter it is, to open the inside end of the resonator. Here it is: http://www.shadowriders.net/forums/showpost.php?p=202821&postcount=332

[UnSub]

Thanks dude. I was curious about it because I live in Cali and we all know how that goes...well maybe we all don't. Basically, they've been quietly moving toward smog checks for bikes for several years now, in which case all the aftermarket pipes go out the window. As it is now, you "can't" remove the baffles here. I gotta get outta this place!!!

But remember, you are not removing the baffles, you are removing the resonators. More for sound, not emissions control. Aftermarket pipes also have removable/replaceable baffles, so depending on the rating they receive for emissions, you might still be able to get away with it. Plus, in such a huge market (California), I am sure that aftermarket providers are going to ensure that they manufacture exhaust that will meet the standards.
Lastly, by simply drilling holes around the "butthole", or drilling out the 1" back end plate inside, even though it will look stock, an emissions test would pick up, if it was releasing any more than the norm.

thanks guys, I'm giving this a go tomorrow on my 07 Spirit C2. Just to be clear, it is a 2" bit correct, and not 2 1/8"

I have an 07 C2 as well and the 2" is the one to use. It will seem like it's slightly too big, but just start out slow, pushing the drill gently and pulsing the trigger, until it locks in. That is what I did, at first I went too fast and it skipped slightly and off to the side. Once it catches, a little WD40 and constant pressure, letting the bit do the work and you're through in about 30 seconds.

Just a word of warning for those who have done the exhaust mod on a stock bike.

I followed the instructions as provided in this post and I'm definetely glad I did it.
Love the growl she makes now not to loud and no longer sounds like a moped.

My girl popped when lifting off the throttle after this mod!!! I assumed my factory a/f mixture screw settings where correct...

Wrong!!!

Plugs where still in so I know she came from the factory the way I found her.

Left side was 1 1/2 turns out?!?! wtf.

Right side 2 turns out?!?! close but no cigar!

Stock should be 2 1/4 turns out.

I followed the instructions on this website http://whytlash.powweb.com/ to adjust my mixture screw 3 1/4 turns out and what a difference!!! No popping and more power. Will need to check plugs this weekend and make any final adjustments.
I recommend you check your mixture screws even if you haven't made any changes you never know if the factory got it right in the first place!!!

[SolCalSpark]

And if it saves mine then you can call me whatever the FUCK YOU want!!!!

Im sure my wife and boys wont mind either


Jeff:biker:

I'm with SoCal on this one, since we both live in SoCal where nobody pays a-fuckin-tention on the road and we have to get noticed somehow...I don't have aftermarkets yet though, so I usually use the shit out my horn and finger.:flipa:

[ahjort]

Any y'all ever bother to just drill a few holes around the central "butthole" of the resonator?
:spank me
I did this on the wife's spirit...3 holes in each pipe, 1/2" diameter. The difference is pretty subtle but it does give it a bit more sound and had no affect on the A/F mixture. She never even noticed it!!!

[UnSub]

Cool man...I had a Kawie rider buddy of mine tell me about that a while ago...thought it might be worth the debate, but I don't think I'll end up doing it...I'll go all out and get some real deal pipes when the budget allows.

[Easyrider Gary]

I did the mod tonight and am very pleased. I should have done it right away. I'm uploading some video's on youtube now.

Hey Gary, you need to either put it in as a link or post the complete URL as what you have doesn't work...

As it is now, you "can't" remove the baffles here. I gotta get outta this place!!!

I did the 1" drill (actually I used a 15/16" drill) through the end of the resonator, plus I also drilled a 1/2" hole through the last baffle plate, it gave an increase in sound especially low down in gear when accelerating.
I was more than happy with the amount of increase noise, but not enough to piss off my neighbors...
The bonus to doing it this way is if you have problems with the local constabulary about changing exhaust or just modifying them, this will look box stock as it comes from the factory...

As for emissions, this mod will not change anything and if they did start checking, it would pass...:thumbsup:

2 into 1, 4 into 2 it's all the same........your removing the restriction (muffeling effect), yeah it'll still be 2 into 1 with a more or less open/unrestricted exhaust flow, which translates into unmuffled exhaust sound. i.e. louder pipes. Or in your case pipe.

For the intent here, though, it's not the same, removing the resonators on the 2 into 1, is a slightly different process with the same result. I think there is a thread on the Aero exhaust.

[durandal]

I did this mod today and I'm overall, very pleased with the sound... as most all agree, it's a temporary thing while a get real pipes. Just one question: I'm seeing/smelling a LOT of smoke coming out of the pipes. Could it just be the excess WD40 I used to cool it down evaporating?
Thanks!

[soxOZ]

OK, after riding with the mod I had previously done (This link (Post 335 (http://www.shadowriders.net/forums/showpost.php?p=209021&postcount=335)) has a photo of what was done) I decide to go the all the way with the holesaw mod.
The only difference I did though was drill with a 1-3/4" holesaw as by doing this I could if I wanted to take it bake to standard or do another mod which I'll show a little later when I've finished doing it.

What do I think, well it's definitely is louder, but not so much to be a pain the the ass. What I do like is when cruzin at 60mph or above it's very quiet from where I'm sitting but roll the throttle open and you can hear that it's a V-Twin and not a sewing machine... :pleased:...

I had a tiny bit of smoke, I think partially the WD40 and possibly a little extra carbon coming out, but it goes away, take er for a good ride, crack the throttle open and let her yell... I had no smoke or smell at all within minutes of riding the first time after doing the mod.

Ya I had a bunch of smoke after start-up also due to wd40! But 10 mins and all burned up, sounds pretty good too!
