Sometimes when i'm rolling hard on the throttle I miss the shift into 2nd. This means im then in neutral and twisting the throttle and accidentaly revving the bejesus out of the thing. Im pulling up pretty hard on the shift lever and it doesnt engage. Anybody else ever have this issue? Thanks | ||

This is likely caused by worn/rounded dogs in the transmission gears. There are other things it could be. The shift detent plate can be out of alignment, have a worn or broken retainer clip, the pins behind the shift detent plate can work their way out causing miss-alignment. You could have a bent shifter fork. | ||

I forgot to mention that many of us have had this problem. I believe the rounded dogs are due to sloppy assembly of the transmissions, where they used a one spacer fits all philosophy for the assembly. If you do have worn dogs you should measure tolerances between gears and use custom spacers to perfect the spacing of the gears to obtain better shifting and prevent the wearing of the dogs. | ||

I had a similar issue with my S2 years ago and found I had a bad shifter drum and two bent shifter forks and that took out the second gear. I replaced all the part and up graded second to the Andrews "s" ratio gears and I made a world of difference. | ||

The worn dogs usually manifest as the bike going into gear, but when you hit the throttle, it feels like a belt jumped a tooth and slams home. | ||

Thanks for all the info, ill have to have them inspected. No slipping or grinding or anything like that, just simply doesnt go into 2nd. As soon as i let off and try again it slips right in like normal. | ||

Try checking and adjusting primary chain tension and clutch to rule out out of adj clutch causing shifting problems yet? A 2002 model year bike could potentially have the issues mentioned above, I know mine does, and 2nd gear seems to be where worn dogs traditionally become a problem. I can post links to useful threads on that later today from my home pc if you want to check that stuff out yourself. ...come to think of it, might be a thread by Reepicheep that I've got the link saved for (I'm planning to pull tranny and replace gears next week).

ALWAYS make sure your primary is adjusted properly. It is the cause of most 2nd gear issues. A mal-adjusted primary will cause poor shifting in all gears. My S1W right now is having a hard 3-4 shift when I'm cranking it, but I'm about 500 miles from service due so I know what's going on. It's just time. Most of the issues manifest first in the 1-2 shift, though, because that's where the most torque multiplication is due to the gear ratios. Check the primary adjustment first, and make sure its in spec. If it won't go into spec, pull the cover and check the shoe. Start easy, don't assume the worst right off the bat. | ||

Hey guys, I'm having a similar issue with my 2000 m2 cyclone with almost 20,000 miles. When the bike is still not warmed up and I engage first gear it makes kinda of a loud clank as it goes into first from neutral. I tried shifting to second from neutral. Same type of noise. It's much less noticeable after the engine is at operating temp hot. Thanks. I'm planning on removing the timing cover for paint and wondering if there is any worn parts I might be able to replace while its open. Thanks. | ||

A clunk going into first isn't that unusual or problematic. The timing cover just covers the cam position sensor, nothing there that wears out (though it can fail). At 20k on a 2000 M2, you should inspect that anyway. You can do that though the oil pump hole if you drop the oil pump. If you pull the cam cover (the larger cover the timing cover is set into), you have to remove one or both rocker boxes to put it back on. But that also lets you inspect the cams (which can wear) and the cam bushings. That cover has to come off to replace the oil pump drive gear as well, on a 2000 M2, it's not a bad idea to replace that anyway (use the new XB part that looks gold). | ||

Myclone2, I read your profile, sorry about your friend. See Ratbuell post above yours. Do the adjustments first and see if that will cure your problem. |
