i need help!!! Everytime i release the clutch, my engine shifts to the left, which causes the chain to shift as well, which in turn moved (and i think bent) my rim. I noticed that the rear engine mounts were loose, so i tightened them, but the engine still shifted when i released the clutch. The chain still stays mounted on the rear sprocket. How do i keep the engine from shifting to the left even after tightening the hardware? please help. I need to know how to do this myself, since i cannot afford to pay someone to do it. Thank you
