FRM sleeve problem.
Going to install some type s piston 87mm bore. Notice i have scars/scratches on my walls. Its not deep enough to put your fingernail in it though. I also notice my old piston has also scars/scratches on them. Whats going on?
Thanks in advance for the help!
Edit: Where can I also buy rigid stones from? Thanks!
