I'm new to this forum, I bought a 2000 scram 400 4x4 for cheap. Doing a tear down and rebuilding the top end. I'm getting confused with Piston and ring sizes. I believe it is all stock but what identifying stamps are stock? I have Piston that's stamped 82.94. 83 is stock bore size. It's a project quad for me and my kids. While I have it torn apart I am going through everything I can. What's some upgrades y'all would recommend? I want to pipe it and jet also, but this is a "weekend" project, gonna outsource what I can't do. But I want to make it fun.
