Hello,
Sorry if I am asking a dumb question. I am not smart enough to know what I am asking here, but did you mean 89.47 (+0.50)? Also, flat top or piano (which compression range)?
Thanks in advance,
Stephen

Did you mean 3rd oversize Euro pistons?

+0.50 is second oversize

I always wondered about that second size (0.08mm over). Is that just for a non-bored fitment (maybe just honed)?
