Im thinking about putting my stock can back on when I do my next oil change. The elbow on my vh pipe is rusty and looks like crap and Id like to try the bike with the stock one any way. I think the carb was adjusted when the previous owner had the dealer put the after market pipe on, will that matter when the stock goes back on? | ||

Yesterday I finished putting a stock muffler back on my 2000 M2. I took off the Vance & Hines that came on it when I bought the bike used. It always seemed a little loud to me, I thought about re-packing it, but the Repack stuff is $30 and a whole stock muffler was $50, so I went for the stocker. Turned out the V&H had almost no packing left in it. I have a Force intake, and Race ignition, and no idea what the carburator jets are. It was running great before, but I didn't rev it much because it was so freaking loud. After putting on the stock, the bike is transformed. It's so much more pleasant, and just FUN. I rev it a lot more, and even use the tranmission much better. I don't get all the stares from other drivers, pedestrians and people standing in their yard, like I did before. I just cruised past a cop doing 40 in a 30 and he didn't even look up. With the V&H he might have come after me... This is the single greatest "improvement" I've made to this bike. I can't feel that I lost any power, it still pulls from low rpm up to 5000 rpm. That's as high as I ever went... There's no noticable 'flat spot' so I'm thinking the jetting is pretty darn close, whatever it is. There's plenty of power still. I can hear all kinds of engine noises now, and brake disk rattle, all sorts of things going on I couldn't even hear before. Still sounds OK, a little more like a Ducati than a Harley now though. And NEVER needs re-packing! I'm sold... (Message edited by jayvee on August 14, 2006) | ||

I'm really suprised that your bike is running smoothly. With the mods your bike has, it should need the extra airflow that the aftermarket supplied. But if it is running good go with it. If you do end up having a rough ride I would adjust your carb. It is easy to do and there is plenty of knowledge in the KV. | ||

I put my stock exhaust back on my M2 and i've got a Forcewinder, Cams and (at least i used to) a V&H. I thought it pulled pretty hard and didn't mind the volume at all. Now with the stock exhaust back on the bike feels weak. I'm working on getting the full D&D kit and a race ignition. Hopefully that will make me happy again. -Barge | ||

Jayvee, From what you describe, I wouldn't be surprised to find that you're running a #45 low speed jet and the stock main jet. That was pretty much a perfect setup for a good running M2 with smooth power delivery. If you decide its time to replace your intake manifold seals, it is real simple to check the jets on the CV-40 and the general cleaning will do it good. If the screw that is part #9 here does not have a metal cap over it, there is a good chance that your carb has already had the low speed jet mod described there. Just doing the #45 jet and the mixture screw adjustment made my M2 run perfect. I didn't drill the slide or change the main jet or needle. And, like you, I thought the exhaust note and sound levels on the M2 stock muffler were pretty close to perfect too. Some of your happiness with it might relate to having recovered a little lower and midrange torque that may have gone away with the V&H's packing. I have this Dyna FXD now and it came with a Screaming Eagle II 16 Guage Shotgun exhaust. It was making me crazy because it was too loud (and it had not been modified either). I found a set of Custom Chrome baffles that slipped right in and solved the problem, I like it now. Jack | ||

You know, anytime it feels like "more power" is needed I just twist that thing on the handlebar, and before you know it, I'm going faster than I wanted too.  Seriously I don't notice any decrease in power, but maybe it's because I'm much more willing to rev it up, now that I can do it without waking/annoying the whole town. I have a little practice stretch with two 90 degree turns separated by about couple hundred yards (and no traffic.) But there's a farm house right by one, I had to take it easy before; now I can downshift twice and hit the curve in the powerband. (I'm practicing on touching down the pegs, haven't done it yet.) I just put in my CCP Idle Air Mixture screw with the little thumb screw into the carb last night. Started it up only, didn't have time to warm it up or adjust it, but at least it ran. The metal plug had been removed, so somebody adjusted something before. I still have to replace the choke cable, from when I broke it during replacing the intake seals few months back. I don't know why I didn't look at the jets then, but I will when I take it off this time. At least need to know what I got in there. | ||

What does the mounting bracket look like for the stock muffler? I have the muffler with a strap that tightens around the end of the muffler but it seems like I need some sort of bracket to bolt up to the bike, the one on the bike for the v&h definately wont bolt up to the stock can. | ||

"Freeflyer" Start asking around for a "Z" bracket. I looked for quite a while before I found one. | ||
| Jayvee |
I think there's a Z bracket on eBay right now, but they didn't call it that. See Item number: 300017592392 it ends in four days. I bought a used muffler and it very thoughtfully came with the Z bracket included, saved me a lot of grief. The V&H rear bracket is completely different. Oh yeah, I tried fiddling with the CCP Idle Air Mixture screw, and I couldn't tell any difference, whether it's 1/2 turn or 4 turns. Either I don't know what to look for or it doesn't work. To be fair, I should mention, I dropped the CCP screw on my concrete garage floor before I installed it, so no surprise if it doesn't work right now. I'll have to put the stock one back in there and test it, it was two turns out. I guess I don't adjust my idle air that often anyway, so I won't bother buying another one ($22).

Jayvee does that bracket look like the right one to you? | ||
| Freeflyer |
Wow what a difference. That V&H pipe was totally empty except for a piece of screen rolling around in there. The engine seems smoother and more solid with a little back pressure. I like that I can get on it a little more without being quite as paranoid, also I dont have to wear earplugs under my helmet anymore, it was weird with the other exhaust it wasnt bad with no helmet but with a helmet on it got really loud its like the helmet acts like a speaker box or something. On the other hand I wouldnt mind just a tad more volume on the stock pipe, but hey good enough for now | ||

Freeflyer: Well done. The stock pipe is one of the best flowing pipes. Not beloved by some, because of its modest sound. Hans | ||

Freeflyer: You can modify your stock muffler if you find that you want a little more sound. A few of us have described how to do it in various threads. I like to adjust the sound level to where I don't hear the exhaust at 70 MPH cruising. Right now I have a modified stock muffler on my S3T and a Wileyco on my M2. Mark | ||

I cut thru the weld on the back end of the muffler. Then cut the connecting tube that went between the core of the muff and the exhaust snout [tailpipe]. Re-welded it back up, painted it and went riding. So basically, the exhaust dumps into the rear chamber and out the snout [like a straight pipe?] Only, it isn't straight, it still has all the tubing and chambers still "in the system" that maybe act like a "shock" absorber? My opinion is it sounds good, like an inboard motorboat. It seemed to lose a little top end, but it seemed to pick up some "off the line" grunt. It is maybe a little easier to ride in terms of sound and usable power in a street situation. I think the power pulses are not as well dampened at low speeds as they were with a freshly repacked glasspack V&H, but the trade off is no repack. I may just need to replace the isolators, but at 65-90 mph, it is smooooth... |
