hey people...just got a 02 954 about 2 weeks ago...there was a chain sound of slappin and we figured my cam chain tensioner was bad....took it out and it was all locked up. ..so glad that was done...but now riding in first gear....i have a weird sound coming from the back....my friend told me my cush drive rubbers looked like they were worn out or looked pretty beat up....you think i need to replace the rubber pieces? what damage could be caused from it? what could happen from those rubber peices going bad? should i replace those 5 or 6 rubber peices or go and buy the rubber pieces and a cush drive sprocket?
