When I first tried to start it I would pedal and sometimes I would get good compression and it sounded like it would start, and sometimes it had nothing
I put it on a stand and pedaled by hand with the clutch engaged
Half a sprocket worth of turning had compression and half did not
Any ideas, or am I looking at the wrong thing
You sir...have a long road ahead of you! From reading your post, it is impossible to diagnose what is going on!
Once a bike is run-in a bit, I can stand beside it, lift the rear wheel, and kick start it with the pedals...by hand, not a chance!
