Clutch shudder, shutter, stutter, or shake occurs on some as you let the clutch out. It's like the clutch is rapidly engaging and disengaging, which shakes the heck out of the bike. Some do it bad enough that it looks like they jump up and down. It usually doesn't do it between gears, just taking off.
If you compare how a badly warped brake rotor on a car makes it feel when you are braking, and multiply that several times over, it's a reaction similar to that.
:agree: Zoom exactly how you said !!, I moved off on mine the other day and lightly feathered the clutch as i knew it would be there!, and f%ck, The thing started to jump in and out of drive as if you were dumping the clutch real hard!!!:cus: and you re right about lack of oil also!, if i park mine on the side stand overnight its worse, but when i park it on the centre jack straight up level, it seems to be a bit better, but laying it on its side with the clutch pulled and waiting at lights with the clutch pulled is a wast of time, the fix is a wavy washer, ( seems to have been put in back to front on production ) :edit: waiting until it warms up also is a waste of time!! , Damn thing has done it from new!!.its only in first gear when you take off, it selects perfect on the move and also when getting neutral!, as i said before on earlier posts i will try and get some pics of the offending parts and part no`s when i pick mike bike back up from the dealers tomorrow!.
