I have 1 coming for next bike. I was looking at using a cvt, but then I'd have to go with a jack shaft too or a HUGE rear sprocket to get an acceptable gear ratio. a chain drive for 79cc predator will fit. everyone is making Honda clones, but the bore and stroke are slightly bigger than the 79, 99cc cousins. other than shrouds and tank, it looks like so many others
LifanPowerUSA has some tech pdf's if you poke around their site a bit, incl a lot of dimensions and stuff ads don't mention. mine is LF160F-AQ
I'm gonna love the low end pull the 118cc will give. 2x more than HS 49cc haha.
Home Depot is where I got mine for, $139 +tax. I'll update as I piece it into my frame
