what octane gas is best for my 2002 CR125? i dont want racing fuel but i do want to get the best performance possible im mixing this gas with Honda HP2 racing oil please give me some advice
Yeah premium should be fine. I mix my fuel at 40:1. Thats what the Honda dealer suggested for maximum performance without too much friction. And i use Motul im mine, it is running rich cause the previous owner just changed the filter,pipe,reeds,and silencer without changing the jetting. But it only pings when the fuel is like 4 weeks old, but only at low RPM's.
