I need the chart that shows what displacement the motor is after a bore. I really need to fuck someone up with some truth.

.010= 64.25mm .020=64.50 .030=64.75 .040=65.00 .050=65.25 .060=65.50 .070=65.75 .080=66.00 .090=66.25 .100=66.50

Not that chart. Thanks

you could just be smart and do a simple calculation.

 

(Bore/2)^2 * Pi * Stroke * 2

 

 

so a .020 bore engine with a stock stroke would be

 

(3.225)^2 * Pi * 5.4 * 2 = 353cc.

If I had any idea what the fuck he was talking about I would. I think he said his .020 over bike is a 370 now. He is just slamming 10 cc into every bore
