My 1995 Kodiak 400 5 speed is hard to get into gear. seems like the clutch drags. can’t turn down the idle enough for it to not grind. the only thing that looks obviously amiss are the rubber bushings in the centrifugal clutch. they are misshapen and hard. can’t seem to find anywhere. can’t even buy new weights, must buy whole clutch assy.($$$) any ideas? Thanks.
