rjmorel - Since we both have essentially the same bike manufactured by Jialing, I'd certainly be interested in how the Lifan engine works out for you. My Jialing needs major work, but I have another 163fml made by Loncin that so far, appears in good condition. If all of my current options fail, I'll also be purchasing a Lifan. The one thing I noticed is that their engine does not come with the sprocket cover. Hopefully the one off your Jialing will fit.
Keep us posted and don't forget the pics, please.
