2wheeln Posted April 11, 2012 Report Share Posted April 11, 2012 Help! I recently got a 2011 Sherco 2.9 and am having problems with shifting the bike. When moving, everything shifts fine, and it also shifts good with the motor not running. When at an idle with the clutch pulled in, I can't shift at all. I cleaned the clutch basket and installed new steel and fiber plates, and still have the same result. I did notice that the clutch basket had some lateral movement. Could there be too much clearance in the bearing causing a drag? This is my 3rd Sherco, and never ran across this problem. Thanks! Quote Link to comment Share on other sites More sharing options...
copemech Posted April 12, 2012 Report Share Posted April 12, 2012 If the bike has been ridden hard in the past, it may have some warped clutch plates. There is allways a bit of clutch drag even on a new bike, but it should not creep forward on its own with the clutch pulled in, possibly a slight drop in idle speed when placed into gear. Fresh oil in the box is usually best, and a light oil like Dex ATF does work, yet if the lever adjustment and pressure feel ok through its stroke, I doubt the issue is related to the hydroulic side and I would consider slight movement in the basket normal mechanically, the plates may not be able to separate properly if there is any warpage.

neo Posted April 13, 2012 Report Share Posted April 13, 2012 Are you sure that the right centre single ball bearing (the one inside the roller bearing thingy) is in place? Best of luck. Neo Quote Link to comment Share on other sites More sharing options...
2wheeln Posted April 14, 2012 Author Report Share Posted April 14, 2012 Bike does not creep forward with clutch engaged. The rod lifts the pressure plate as much distance as my other bike, and it is also is lifting evenly. The bearing in the centre of the basket has never been replaced, so it should be the right one. I have some time tomorrow to clean up the tangs on the fiber plates, maybe they are dragging on the basket not allowing separation. Quote Link to comment Share on other sites More sharing options...

Sorry, I mis read your original post where you stated you had installed new plates. As you did not state if this bike were used or newish, I would still think you are on the right track, May need to smooth the fingers of the outer basket if grooved.

I have the same problem with my 2010 290, I can take the plates out, clean them up change the oil and it works perfectly, leave it overnight and the clutch is suck until the engine gets warm or I bonce the bike back and forth in gear to free it off. Take the plates out put them back and its fine again even when cold ?? Quote Link to comment Share on other sites More sharing options...

Take the plates out put them back and its fine again even when cold ?? That's normal (usual). Try one of these oils and give it a couple of days to soak into the plates before your problem stops. Castrol 5w30 Edge Sport - Synthetic Nulon 5w30 Long Life Diesel and Petrol Oil - Synthetic 450ml for a refill ... no more than this. All the best.

tony27 Posted April 22, 2012 Report Share Posted April 22, 2012 Might have to try that Neo, couldn't get my clutch to release at all today until I resorted to removing the clutch cover & seperating the outside plates with a screwdriver with the lever pulled in. Never had that happen before. Riding around standing on the brake trying to unstick the plates may have contributed to me blowing the primary seal in the brake master cylinder today Quote Link to comment Share on other sites More sharing options...
neo Posted April 22, 2012 Report Share Posted April 22, 2012 Nulon is the best of the two. But if they're sticking that bad I'm guessing there's a tacky residue on the plates. Might be worth cleaning them in petrol first, then filing up with Nulon / Castrol. Let us know how you get on. Best of luck. Neo Quote Link to comment Share on other sites More sharing options...
