I'd sure like to know as well. Mine's a B. Why are there different ones?
A is smallest. B is bigger and so on. My b has done me well. Don't get a piston larger than your cylinder.
do you know how much of a size difference. i seized my C, if i have to hone it out could i use a D. or just stick with the C
Honing will not change the nikasil that much and you shouldn't hone it anyway
