here you go that motor is only 145.1ccs



Take the bore x bore x .7854 x the stroke and you will get cubic inches which comes out to be 8.86ci. Now take the ci 8.86 and times it by 16.386 and you will get ccs 145.1 not 150ccs

You should check your calculator







Input Parameters Are the Following:

Number of Cylinders are = 1 to 1

Piston Diameter = 2.283 Inches

Piston Oversize = 0.000 Inches

Engine Stroke = 2.165 Inches

Computation Results:

Computed Engine Displacement (CID) is 9

Computed Engine Displacement (Litres) is 0.1

Computed Engine Displacement (CC) is 145.2



Still not 150ccs

maybe we should check piston sizes.



138cc kit = 59mm piston (correct?)

134cc kit = 58mm piston

Wow you guys seem to know your stuff about this. I just put it together and haul A$$. It looks like its only a 150cc. So how can I get more juice out of this motor? Thanks guys.
