What kind of rpm are you turning with .8mm?
Have a Harley, spent lots of money on it, thought I had a fast motorcycle, bought a Busa, realized all I had was a fast Harley, not a fast motorcycle!

One time i used 0.7mm with stock rods, i had Wiseco pistons, part number printed on top of piston,
when taking the engine apart later, i could read the number from the head, backwards
