hi guys,
i have recently began actively enjoying my bike. the clutch is slipping terriably. intend to replace the cable, springs, fibers and metals. what is reccomended? if oem is thought the best;where can i buy items affordably? the bike is a 1976 yamaha ty250 . i have many videos and books on the subject. it is becoming something that i want to do with my family.

btw i stand 6'9' tall and weigh almost 250 lbs. any suggestions that will help me fit bike to my frame and set suspension will be appreciated.

thank you
