Just got some specs on my 138cc lifan engine.

[Mick]

The yanks on PlanetMinis are saying that lifan make a 138cc engine, And thats what mine is, Not a 125 with a 138 bore kit.

Heres some specs from the site.



Lifan 138c
54mm Bore
55.5mm Stroke
27/23 Big valve head
71mm Cam
13BHP

Sounds good to me.

the lifan 140 has 140cm3 stamped on the barrel and is a kick in gear gearbox..youve got a non start in gear gearbox which is a 125 gearbox..they made a 138 kit for that engine..genuine lifan 140 has a different clutch cover to the one you have because the clutch is more central to the engine rather than at the front...

yep i have the lifan 140 not 138. not sure the 138 is 13bhp tho

[evopitbike]

my lifan 140 say 140cm2 or summit . not 138 i heard there a fake lifan 140

[physco_nutcase_danny]

lifan didnt make a 138 engine..why would they make a 138 and a 140???no point..the 138 is just a big bore kit for the 125 bottom end...a genuine lifan 140 has 140 stamped on the barrel and a kick in gear gear box.

lifan made a 107cc 120cc 125cc 127cc 140cc 150cc
