Here are the specs that came with our Lifan WIN138.

1P55FMJ-2E10
Displacement: 140ml
Bore×Stroke: 55mm×59mm
Max.Power & Rotating Speed: 8.0kw/7500r/min
Max.Torpue & Rotating Speed: 9.5N.m/5000r/min
Min.Fuel Consumption: ≤367g/kw.h
idling Speed: 1500r/min
Ignition: CDI
Lubrication: Pressure/splash
Transmission: 4 speed
Not sure how to read their power ratings and convert it to HP , and TQ figures that make sense ?
I will try and get a picture of it.

about a year ago I started to do some comparison testing and get info, but not alot of people were helping and the threadcrapping just wore me out.
The obivious differences are the piston pin, 13 gpx or 14 lifan for off the shelf pistons.
Cylinder lenght, I think it is 68 and 78.
The lenght of the rod is 100mm for most.
Stroke are 54,55.5,57, and 59 and you can use offset pins also.

Here are some pic of some model testing that I was doing, it represents my lifan 120 monster, 55.5 stroke, 100mm rod and 14 pin. Some claimed they had big bore kits and pistons for the 14mm pin, but when I plugged the numbers in piston pin center to deck height showed problems.

I hope akunar has some pistons for my sons motor.

FYI, Coolster and SSR use Zongshen for their 125s. The new 150cc Motor that OGM, Pitster, Killer, and SSR use YX Factory Motor. Apollo (used to be orion) uses the Ducar for their 125s (they are switching to ZongShen for one bike and Lifan for another). VIVA (Nitro) uses Loncin.

A little added info on the TRUE 140 Lifans: The 59mm stroke motors use a 15mm piston pin (the rest use a 14mm pin), and Akunar has excellent knowldge and parts for all of these motors - email "Ben" at Akunar...
I'm currently building a 'square' 59mm stroke Lifan with a 59mm bore hi-comp. piston from Akunar and a 'special' head from same with 24/28 valves. Ought to be a beast. These heads come with really nice ports stock, and a decent cam, but I opted for their 7mm lift A2 grind cam just for fun. I'll try both with 26 and 28 Mikunis and with/without IRK/slinger, and let ya'll know what the dyno says before we mount it up in my perimiter frame 14/12 roller with FastAce AS-02 and BS-66RC suspension...
Prolly gonna go Motard with this bike on 12x2.15 and 12x2.50 rims and some Brembo calipers I found (radial 4 pot in front and super little 2 pot in back - gotta make some mount brackets up soon....). Opinions ???
