I have a 94 KX250, I have been running Klotz R50 since the current rebuild (Super M for the breakin period). I mix 40:1 w/ 91 Octane Premium, I love the smell of this oil and haven't had any problems, no fouled plugs, and it doesn't smoke very much. However, I have heard plenty of horror storys about people experiencing a lot of carbon and rust with this oil? What is your experience with it?
I usually ride medium trail speed, where I usually don't rev it that hard, But sometimes I really rev it a lot (racing buddys, sand, etc.) and that is where I feel I need the extra protection.
Your input and advice would be greatly appreciated!
