Well got the ole girl out of the garage Saturday washed her down & tried to take a ride. Started off good but seemed weak(not normal!) about a mile from my house bike stopped dead in the road. Soon figured out rear wheel was locked down ! After sitting a few minutes I headed back home with a bad drag on rear wheel . Locked again in drive way but got her back in garage. I think clutch got a little overheated. Played with it a little today. Bike will roll free as long as I don't touch rear pedal ,as soon as I do wheel locks again. Loosened the bleeder & they unlocked. Do I need parts or try changing fluid ,master cylinder ? This could have went bad really fast, NEVER had this with any previous bike!
