My '02 M2 has a habit of lunging forward in sporadic bursts in first gear until it warms up. If I accelerate too much, or let the clutch out too slow it feels like I'm pulling the clutch in and dropping it a few times. Does anyone else have this and is it a sticky clutch that needs adjusting or is it (God forbid) a sticky piston that is not lubed enough. Whatever it is it annoys the shit out of me! | ||

Isn't that what they call, slippage? How many miles are on that beast? | ||

First of all, let it warm up first. If you ride without it warming up you are running the risk of a gasket leak. Second, adjust the clutch according to the service manual and re-adjust it at every oil change. If that does not work pull the primary cover and check the status of your primary chain adjustment shoe. | ||

Is it the engine surging or the tranny doing odd stuff? Is your primary chain adjusted correctly? | ||
| Cyc02 |
Okay, here goes - It doesn't quite have 11,000kms on it. I do let it warm up although not for too long because of it being air cooled. It has just been adjusted at its 10,000km service. Sometimes it is worse than others. 1st gear only, it just leaps forward like I've pulled the clutch in half way then dumped it. It may do this once, twice or three times until I change into second cog. I hope it's just an adjustment and nothing too serious, cause the fella who owned it before me babied it to the point of ridiculous and when I got it @ 2257kms had already had its 4,000km service and it didn't get ridden much in 4 years so I'm thinking maybe all the internals are gummed up? I've put nearly 8,000kms on the clock since 2006 and I would've thought I'd have blown the cobwebs out by now! | ||
| Brinnutz |
Yup, I know exactly what you're talking about. Like when you're accelerating. But it only happens in first gear. Yeah, no idea what it was, still did it when I last rode 8 months ago...but not all the time. It's weird. | ||

If it's like a missing tooth on the belt kinda jerk, it's worn out First Gear dogs. semi common problem on old trap door trannys but easy (sorta) fix. Pull the tranny out, replace the gear, put tranny back in. There's some other posts about it here somewhere,With pictures, just do a Search. | ||
| Cyc02 |
Could a worn out first cog be due to changing down to first for slow corners? I was told that they were built to handle that sort of thing by my mechanic and he thought it might be a sticky clutch?!?! | ||

If you are in gear with the clutch let out and pulling away from a stop and it "jerks" like it's missing a tooth or two, the clutch aint stickin. It comes from what we all do on a Buell, we grab a gear and GO. The H-D gear wears out,the square surfaces on the dogs get rounded off and that's when they jump in and out of engagement. Pull the tranny, inspect, get a Andrews replacement and go grab some more gears. | ||

I had an issue that I described as feeling like I had gone over a wet man-hole-cover on full throttle. Or a mouse riding once around the belt. Replacing second gear was the solution. Between parts and labour, even with me pulling out the tranny, it was expensive. | ||
| Jc000 |
Have the same exact issue. The shop reckons that one of my clutch plates was loose which they replaced. I'm picking up today, so we'll see if that fixed it. | ||
| Buellistic |
Had the problem early on because of #13 foot abuse to transmission ... Took shifter fork and low gear replacement to correct ... MAY THE LONG LASTING BUELL BE WITH YOU !!! | ||

Sounds like worn shift dogs... but I also had a nearly bald Dunlop D220 give a similar effect. | ||
| Brinnutz |
Can anyone post the proper part numbers to replace these dogs? | ||
| Limitedx1 |
#771-97689 beagle, and #23-09273 pomeranian  | ||
| Buellistic |
Brinnutz: These pat numbers are in the FACTORY PARTS BOOK you should have for you YEAR and MODEL BUELL ... FIRST GEAR: GEAR,1st-mainshaft PN 35762-89A GEAR,1st-countershaft PN 35763-89A SHIFTER FORK: SHIFTER FORK,first and second PN 34142-89C These are the same transmission parts the are used in the EVO SPORTSTER and BUELL "BLAST" ... THEY CAN BE PURCHASED AT ANY "HARLEY-DAVIDSON" Dealer !!! MAY TH LONG LASTING BUELL BE WITH YOU !!! | ||
| Brinnutz |
Well, when you say shift dogs, I have no clue what you talk about because that's not what they are "techincally" called in the book, LOL | ||
| Hugie03flhr |
I'll go with (sloppy primary chain adjustment)for $0.00  Harley engines are not balanced very well  as you can tell and when it lumps around in 1st gear with a lose chain it is very noticable! | ||
| Brinnutz |
Hugie, I'll let you know if you're right as I had (still probably do have) the same problem as Cyc did... Mine started doing it in second gear eventually. But my motor will be up on the bench this weekend or next week and pulling stuff out. | ||
| Reepicheep |
You can see the wear on the dogs. The dogs are actually part of the gear pairs, so if you are slipping in second, you have to replace the second gear pair, one on the mainshaft and one on the counter shaft (from what I recall when I did it). Also inspect the 5th gear drive assembly while you have the tranny out... it remains captive in the case. Inspect the needle bearings. Lafeyette, how did you determine your fork was bent? Bent forks are pretty common on the imports, but I think I would have an easier time bending an I-beam with my pinkies then bending one of those sporty shift forks... those things were massive! Now I did have some gouging on them, but that cleaned right up with a small file. Mine wasn't bad... even with a trashed countershaft. Or was it mainshaft? And a 5th gear drive assembly that needed new bearings... I think I ended up under $300 out of pocket for the whole mess... cheap for a tranny rebuild (IMHO). You need some sort of mondo snap ring remover if you need to get one of the shafts out. | ||

the Dogs that are being described could be called lugs too I have the lurch too first only feels like the clutch is jerked in and then dropped, only on take off from a standing start. I used a mirror to look at the 1-4 pair the area of the dogs that I could see looked ok, go figure... | ||

LimitedX1, those are the wrong numbers, they should have started with ,,,,,,,K9....  | ||
| Hugie03flhr |
Btinnutz, The other reason I would say it is the primary chain adj. is you stated it happens when the bike is cold. That is when your Prim Chain has the most slack. | ||

My '96 S1 wasn't shifting smoothly going into second. It would engage and then "thunk" into gear. My son pulled the transmission out and found worn dogs on several gears. If you look at the pictures, you'll see rough rounded edges on the engagement "dogs."   and a couple pictures I had gotten elsewhere:   | ||

I picked up the bike today and drove her home approx 60 miles. Sure enough I was turning from a red light in 1st and it "slipped/lunged" again. So far I've had it looked at three times by two different dealers and no one seems to be able to figure it out. Buellistic gave me some advice which I'll try though I'm really not comfortable with messing around in the primary. I wonder if there is a way to bring this to Buell's attention. I don't really know if there is much they can do, but that's weird that it seems to be affecting these 3 02 m2s, and no one seems able to pinpoint it yet. Maybe they heard about this from other owners and have a fix? | ||

Thanks to all of you - the response has been overwhelming! I'm getting my mate Herb to run the spanners over my M2 in a few days time so at least I will go armed with a few different possibilities for him to explore! I can live with the "lunge" for now as long as it's not damaging the donk or anything else. I can live with a tranny rebuild providing it is going to fix the symptoms. As I've said before it's usually only for the first 10-15 mins of each ride... | ||

BUELLers: "i" find it is best to talk PART NUMBERS so everyone will be on the same page ... My intent is not to be rude or seem to know a lot !!! Those of you that can post pictures, THAT IS A REAL "PLUS" !!! MAY THE LONG LASTING BUELL BE WITH YOU !!! | ||
