Anyone out there who knows if is it better to breakin in a new piston and sleeve kit before you try to modify it or after you modify it? I read a really nice article on engine mods here http://www.rcuniverse.com/forum/m_5226191/tm.htm so I worked on my crank while i had my engine apart. I think it came out pretty good. this is what it looks like after I got finished. Any suggestions? Right now it is very polished, does it need to roughend up any?
