I just put an V&H pipe on my 2002 m2. 1st of all it was very difficult to get the stock pipe off. I basically had to lay the bike almost on its side to get it out. 2nd, I had to force the new pipe in place because it did not fit/ lie where it was supposed to. I then had to drill a new hole so the front mount could fit in. I still don't think I have the rear mount tightened enough because I just cannot get tools in there to thighten the bolt and hold the nut at the same time. How did you guys do this? Sure is a cool sound though. I have a 195 jet and a 45 jet, are these the correct ones. I have heard to put a 48 pilot and add that washer to the needle. Will this give me more power? Do I need a forcewinder or k&N air filter?? The bike seems to almost be a bit slower than before!! Is this normal or is it just the jetting problem. sean | ||

Did you remove the stock Z braket? I see that left on many bikes and it makes the pipe hang low. It sounds wierd that you had trouble getting the pipe off did you remove the header? | ||

Good point on the Z bracket, common mistake. Also, '98 2.5" collectors (S1W/S3) are in a different location that '99 and later. Mixing and matching mufflers across these headers will result in the front mounting hole not lining up. Is it possible you got the wrong muffler? 1/4" drive + a combination wrench is the ticket for those rear upper bolts. | ||

Yes I removed the rear Z bracket where the stock muffler was attached. All I removed in the fromt was the clamp holding the pipe onto the exhaust and the bolt holding the pipe to the front bracket. That front bracket just hangs down so low that I had a difficult time getting the pipe off because it would either hit the front mounting bracket or the ground. Do I need a 48 pilot or is a 45 ok. Is it worth the effort to put the washer on to raise the needle a bit?? Thanks for the help, sean | ||

Sean: I think his point was that if you loosen the four nuts that hold the header to the motor, the muffler will come off without having to lay the bike on it's side. Jetting advice on the internet is all pure speculation. People can tell you what works for them, but that may or may not work for you, every motor is different. If at all possible, get it to a dyno, preferably one with a sniffer. | ||

I use a adjustable needle so i do not have to shim. I also run a 48 pilot jet it makes it run a tad rich on idle. But when you get on it from a smooth crusing speed she goes. | ||

Aaron, I apoligize for being such an amateur, but what 4 nuts hold the header to the motor. Where/ what is the header? I ask because I am think ing about putting the stock pipe back on to regain the power I lost. sean | ||

Sean, Follow the pipes up where they each attach to the heads. Two nuts on each pipe. By loosening them up a bit you can get enough wiggle out of the header assembly to manipulate the muffler into and out of place. At least that's what works for me. MikeJ. (That post reads funny somehow.) Oh well, it's just nuts and bolts and such. | ||

Sean, no problem. The header is that set of pipes that come from each head down to the collector, where they join together, and where your muffler attaches to them. There's 2 nuts at each head, going over studs, that attach the header to the motor. If you loosen these nuts, it's much easier to get the stock muffler in or out. The studs like to break, BTW, and they can be a pain to fix. My personal theory is they break when too much movement is allowed in the whole system, i.e. worn front muffler bushings and the like, that flexes the studs and fatigues them. Your '02 has a new improved front mount that stiffens the whole assembly up, though, so hopefully you won't have a problem. Also, you want to make sure bolts slide in and everything fits without being forced into position. Your V&H should perform somewhat better than the stock piece, particularly through the midrange where the stock pipe generates some reversion. Not tremendously better, as the stock Cyclone cams don't have enough overlap to abdicate much control of the powerband to the pipe, but somewhat better. You probably just don't have it tuned right yet. Like I said, get it to a dyno, preferably one with an a/f meter. I'm still curious about your front bracket and having to drill another hole. Are you *sure* that V&H is made for a '99 and later? And not a '98? That would explain it. | ||

Aaron and Mikej, Thanks for the info! I am sure it is for an '02 M2 and not the earlier version. I did not have to drill an entire new hole but just had to make the original one a bit larger as it just did not match up with the mount. I'll bet if I loosened the header and then let everything lay where it wants, the hole should match up. I seem to be slower than stock, so do you think I should go the a 48 pilot as it seems to be running lean? (I think it is running lean because it seems to run better when I have the choke out a little bit) Should my main be a 195-which I think it is now? I really need to know the answer to this to help save time and energy. I absolutely hate being slower than before and might get nervious if that Japper pulls up next to me and wants to see what I am made of!! Thanks again, sean | ||

Marlboro man, did you change the intake at all? | ||
| Archer |
what size slow jet comes stock in the M2. Any body know???? | ||

Sean hasen't changed the intake yet. I've got a K&N we are going to install in the stock luggage airbox. I want to put in the velocity ring also but we are having problems finding one locally. It would be fun to experiment around a bit with the stock snorkle tube and a cone filter aka Force. Just leave everything inside the stock box. I guess both work fairly well. So Sean, when you going to be up and round again? Brad | ||

O.K., here's what's going on now. My bike is now in the dealer for a leaky fork fix. I told the tech. there this story about poor performance and he said it needs a 48 jet for sure. This guy is even going to do it for free! So, I'll have to let you guys know the outcome in a few days when I get it back. Brad, thanks for the offer to do the jetting, but I still need that K&N. I go in for surgery next thursday to push my intestines back in where they are supposed to be  | ||

Cool, you are a gutsy guy eh?  Best wishes for a quick and painless visit to the hospital. | ||

Marlboro, Good luck with the bike and the surgery. I had a double hernia. Fun does not describe it. | ||
| Marlboro |
Got my bike back on Saturday and am very impressed with the outcome! It is almost like riding a completely different bike. The combo of the V&H pipe and the 48 jet makes the bike about as fun as it can be, though I have not messed with the intake yet. Still not as fast down low, but it is quicker mid and high, much quicker. It seems to warm up faster and just ride smoother overall. I am pissed though because I set the appointment about 3 weeks ago for the fork fix and I go there to pick it up and the guy says he had to order some gaskets or seals for it. Don't you think they could plan ahead a bit?? I also put those Buell grips on which were a very wise investment. They take away some vibration and give the bike a much more sturdy feel when riding. Thanks for the thoughts on my surgery. I am crossing my legs, I mean my fingers  . sean | ||

Bluzm2 and Marlboro, "I want to put in the velocity ring also but we are having problems finding one locally." I actually ended up with an extra - when I put the K&N filter in the stock breadbox, then I decided to just bag that and put on the race intake which came with one too. I would be thrilled to get rid of it, I can't see needing a spare(velocity ring), ya know? It just sits there on the shelf and mocks me... That reminds me, anyone want a K&N airbox filter with a couple hundred miles on it? Not using that either- just tell me where to mail them... -Mike | ||
| Bluzm2 |
Sean, I'll let you decide but the filter/velocity ring route is very inexpensive and works well. Plus you get to keep you "luggage" I'll let you work out the details with Mike. I'll help you with the install/mods if you want. No heavy lifting now OK? Good luck on Thursday, let me know how things go...  Brad |
