You'll also be pleased to note that they are actually stroker cranks which are +3mm increasing your cc's if you have a 44mm Piston its
3.1416 x (44/2) x (44/2) x 36 then divide by 1000 = 54.7cc
Smokin!

Being stroked will that raise my compression ratio aswell?

I would if you didn't lift the barrel :lol:
Fitting a full circle crank is not a job for a novice.
You need to space the barrel to suit
There is little to gain if you don't port it and run a real reed cage etc.
:wink:
