I'm rebuilding a 400ex motor and got to the new rings/piston. Piston kit install sheet calls for .019 gap on rings. I had .015 on the top and .009 on the bottom ring. I filed bottom ring to exactly .019 without issue but went a little too much on the top ring ( ended up with .021 gap).
Is this OK to go ahead and assemble? It's not even mine, I'm just rebuilding it for some kid but I want it right. Please let me know if you have experience in this area. I really want to rap this job up today but all the stores are closed.
