Clunky gears help
 
Hi guys I have a 2009 xt660r in excellent condition only 7500 miles give it a full service around February runs well my only niggle is the gears are very clunky going in is this normal or is something wrong it goes in gear ok butt ust feels clunky going in

A clunky gearchange can be because of a poorly adjusted chain (too slack).

I'm not sure why, but simply adjusting the chain improves the gearchange. You may also want to check the amount slop in the cush drives.

Old oil, wrong oil, contaminated oil, oil too viscous - sticky/swollen friction plates and/or clutch drag?

Too much freeplay in the clutch cable - plates not fully disengaging?

Missadjusted clutch - lever arm in the wrong position? Do the punch marks line up on the arm and casing?

Thanks for reply it's got new oil in I put 5000 motul in new filter new chain and sprockets which has right adjustment . I think it could be the clutch needs adjusting when I start bike put it in gear it wants to jump forward

Your clutch not slipping at all Ohlins ? I've heard of them slipping with fully synthetic as opposed to semi-synthetic ? Maybe its the ambient temperature that makes it Ok in your bike.

My clunk was all but gone for doing the Kev's Cush drive, & Twist grip Mod's.I also found riding like you stole it made for smoother changes rather than being a bit tentative. Not sure if its just me but it also feels a lot happier on the rough stuff than tarmac.

Thats the trick with all big singles..... to easy to use to lower revs
really they don't like it.. they are torquey but NOT flexable...
big singles are not nice motors...
