Put a big socket or a crescent wrench on the comp. sprocket nut and turn the engine over by hand several times with the bike in neutral, skip all the gorilla **** pushing it around. Your so busy pushing and breathing hard you can't tell whats going on with the motor. If you have engine problems you'll feel it through the wrench or hear it doing it by hand.

 

you said you load tested the battery, have you cleaned all the connections between battery posts and starter? By the looks of things you picked up a hell of a good deal, congrats. I love my shovel to death. Good luck and let us know!

 

yes I cleaned all the connection, I even bought all new battery cables and everything and I took and sand paper and sanded all the metal down so I know it's all making a good connection lol. Yes for what I paid and for what it has in it I love it, I upgraded all the rubber mounts, and what not so there is no vibration when riding.
