For those of you who have been thinking of doing this kit should do it. I just installed it and wow the bike has so much low end it's crazy. I have stock gearing I think it's 13 36. My buddy has the 88 kit with the 20mm carb and mine with the 108 and 24mm carb it pulls down low like crazy. It's almost scary to be honest with u all. First gear crack the throttle and it wheelies. If anyone is thinking of doing this kit do it. It's worth every penny. Any questions just ask.

Best thing ever. Carb was tight I had to bang in the tank a little. A 24mm carb is huge, they sell this kit with a 26mm that's just nuts

Only fun in the pits, ice racing or on the tar. There is nothing like 3rd gear power slides on wet tar with a atc70

How would it compare to the Lifan racing engines?

I don,t know I have never built a lifan motor, I have built yx, zs, and a couple of Zhongshan motors. I would love to have the opportunity to build a lifan 140

I have seen the 250r vid before and that is what I am talking about. Is the trike yours? Tblumber.
Hay I'm just kidding. I ride a stock Xmas special most of the time. The 184 is too much to ride and not as much fun as most people would think.

I like it when people build there own motors instead of buying a off the shelf 124 conversion bolt in. Fannitti keep it up!!
