I had to bend the muffler to clear the front motor mount and pedals and add a tensioner/chain guide but now its a fully functional bike. I still have to add the drive chain/tensioner, gas tank, cables, throttle, speedo, oh and trim the chain guard to clear the motor. I know I'm probably forgetting something but I'll remember cause right now it's all mock up cause I want to paint all the silver mounts and brackets so it look like it came from the factory motorized.
