I have a 1974 TX500A as the title says, and the clutch wont disengage. It happened while riding a few years ago. Shifted to first at a light with the lever pulled and it stalled. Ever since that day the clutch wont disengage the tranny. Have inspected the plates and measured everything seems to be in spec. The basket moves upon pulling the lever, however when its adjusted to allow that to happen, the kick start wont engage the motor. I have alot of car and small engine experience, but little with these old wet clutch's. Have put everything together according to the yamaha service manual for the bike and still wont disengage. The basket cover of the clutch separates from the plates, but have not been able to see if they separate when running. Basket does have some marks from plates, but nothing major and sanded down and small ledges it did have. Have two bikes, may swap this top end onto the other bottom end, but would like to figure this out. Any help would be greatly appreciated
