Where Can You Get Lifan Stroker Cranks

[rough Nut]

Hey Guys,

Just wondering where you might be able to get Lifan stroker cranks, I've heard of them, but do not know where to find them.

Any help on this subject is appreciated.

Cheers

I guess you've already gone to (or aiming for) maximum practical bore size for the head gasket, and found yourself a good hi-comp piston.

Since by today's standards, isn't a stock Lifan 150 already a stroker?

I know it's only a 2 valve engine so it wont breath properly if too over square, but to compare against something, the Lifan 150 std crank stroke is only 4mm less than that in a modern 250F.

Lifan 150 std bore = 125% of the stroke.
Modern 4-stroke bore = about 155% of the stroke.

Not trying to be a smart arse here! Just curious about the upper displacement/rev/breathing limits of these little scooter engines. I believe that peak piston speed is a key variable for when these engines will blow up.

As if, and why make a motor with a wacked c/rod angle anyway??
