boghopper350 Posted September 4, 2013 Report Share Posted September 4, 2013 What plug are you running in it? Quote Link to comment Share on other sites More sharing options...
axulsuv Posted September 4, 2013 Report Share Posted September 4, 2013 Start with the basics .... Clean your air filter !!!! Quote Link to comment Share on other sites More sharing options...
mokwepa Posted September 4, 2013 Report Share Posted September 4, 2013 (edited) Clean air filter first as said above and keep it clean. What plug, gas/oil ratio and what 2stroke oil are you using? FYI: if your airfilter is dirty, your engine cant suck through enough air and will compensate by trying to suck more gas out of your carb, causing it to run rich. Too much oil will also run rich and fowl plugs. Cr@py oil will also burn bad and fowl the plug. I clean my filter every second ride (I ride abour 2 hour every day). I use Belray H1R oil at a 60:1 ratio (150ml to 10l gas). Plug im using is a NGK BP6ES (this will vary according to location and temp).

dan williams Posted September 5, 2013 Report Share Posted September 5, 2013 I run BelRay H1R at 100:1. If you tend to ride hard 80:1 is fine. Quote Link to comment Share on other sites More sharing options...
