so just normal wear and tear huh.... i got someone replacing it with a polaris clutch i believe
how many miles did you have on each before you noticed cracks ?

what do u think about using a polaris clutch on it
i thought i read you cant beat yamaha clutches .....i coould be wrong .......never herd of polaris clutch on yamaha ....seen some commet clutches on them ...
the polaris p-85 works well on yamahas. you need a different bolt to hold it on, and someone who can lead you in the right direction for set-up.
