it means your clutch plates are wearing out.
not necessary to change immediately. but if you want, can get the
full set at FJT/eversuccess for less than $130. get both metal and
fibre plates. the last fibre plate must have the rubber thingy
around the teeth. remember that. very important.
clutch plates very easy to change.
take out the mid fairing, loosen the bottom fairing. take out the
clutch cover, unscrew the 5 nuts u see there, take out the clutch
springs, take out the metal cover. then slowly take the plates out
1 by 1, those inside use a flat screw driver to dig out, but dun
apply too much force or you'll damage the housing.
