Sure is...What supplier did you buy your kit from. First time I've seen one included, but then again I've only bought 3 engines from two suppliers. The second and third included a wheel puller.
Yes put locktitie on everything you can. I drilled my bike and the chain alignment from motor torque is right on. I put a hose clamp around my frame and muffler to realign till i get my new motor mount. Heck the new motor kits im buying come with the larger hole in the motor to accept larger frame bikes.
