Coming down China Wall this past weekend my bike locked up. I wasnt riding it hard just cruisin down and the boom, locked up. can get the tire to move with clutch in or get the shifter to move. I can kick it about 3/4 the way and am getting compression and moving the pistons so i am to believe the problem lies in the tranny. Any other opinions or know what it just might be? if sohave a estimate on know how much it might cost to fix?
