How do you find out what a cylinder had been bored out to? Or if it has been. And if it needs to what size pistons do i get? etc etc?

When people say they bored there cylinders 2 hundrits over that means the bore size is increased by 2/100's of an inch. Usually inches. Thats why you see sizes in the Wiseco Catalouge

STD=Standard

0.020=2/100" over bore

0.030=3/100" over bore

ETC

People may also say... "i got mine bored out Twenty Thousants." But if you remember elementary

20/1000 also = 2/100

Do dis make any cent :huh:

Lechicharon, the reason they say thousandths is because that is what you measure you piston and cylinder specs to. If you measure to the hundreth you will not meet clearance specs.
