Thanks for the info. Still appears I would have to get my hands on one to truly know whether a direct bolt in swap (seems unlikely at this point) would be possible. That CG125 engine is interesting to me ( from an engineering standpoint) as it was not used in the US, performance potential seems limited, but article about it touts its reliability. Talked to somebody at Skyteam Headquarters on the phone and he said the Ace125 should be here in the US around June.
