I got a motor from a guy that said it had a gytr clutch in it and when i put the motor in my frame and hooked everything up got it running and with the rear jacked off the ground i could not get the clutch to disengage adjusted everywhere i could and still no go i took it apart and using the manual i downloaded from here put it back together along with the cushion spring every looked fine so i didnt worry. Fired it up again and still the same issue so i removed the cushion spring and now it works perfectly. So my question now is I just put a gytr clucth kit in and didnt put the cushion spring back in. What does that thing do? Do i need it? I couldnt get the clutch to disengage with it installed. any input in greatly appreciated.
