go with sand sharks more of an everything tire .. .. the tires you are looking at are more designed for strait line ,
also you have a fourstroke so i would go with a little taller tire , you have the low end to turn them !!
guys what do you think ?
also the higher octaine fuel dont keep it cooler, it just keeps you from blowing up your engine , due to the under sea level and the 10 % humidity !!
you have to rejet it fat ...........
