piston change
HI gyus ,i opened my engine to clean a power valve ,and i decided to change a piston .My cylinder is size A ,but my piston is vertex size B-71.95 .My question is what size to be a new piston .If i put a next size 71.96 ,the clearance will be only 4/100mm ,which is too small .What is the size of A cylinder i think is 72.00mm ?And second question ,why wiseco pistons are only in one size ?

An "A piston" is smaller than a "B piston." Put in another B piston.

I don't understand your question..
Though, I will say the same thing. Run a B piston. Pro X makes A, B and C sizes. Here are the part numbers: 01.7300.A 01.7300.B 01.7300.C |

Your cylinder was probably worn a little and a previous owner installed the B piston to account for the wear. I'd put the Wossner B piston in it, if it were mine.

What do you think about the condition of my current piston is there still life in it or better not to risk and to put new one .Thank you !
