However, there’s no valves that you have to check periodically on a 2 stroke. For example, you might get 150 hours of trail riding on a 2 stroke top end, but a 4 stroke ridden the same way might get 250-300 hours before needing a rebuild.For 4-st it’s fairly linear with rpm, more rpm, more advance. 2-st are not. If you look at most 2-st timing curves they start out advanced and then it’s reduced at higher rpm. Small changes at high rpm can make differences is power. The only real way to verify what is needed is to do dyno runs at different timing.
