Looks good. Two small tips though:
-I would run a disc brake on the back, chinese mags don't like rim brake setups and there have been numerous failures where the sidewall of the rim gets thin and bursts.
- Careful with that engine mount, they are known to crack right at the frame - especially your model without the reinforcements they added later on. Correct fix is to chop it off and run a CNC mount on the front, but you can make it live longer by properly shimming the engine so it sits flush both on the seat post and the front mount before tightening.
