I have a 2002 Banshee thats due for a rebuild. I'm thinking of modding while i'm at it. I dont wanna go for a big bore kit so im thinking how high i can go on the stock.

i was riding my banshee today and it was running Chevron gas 89 octane. i was smoking a Raptor 700r a LTR450 and a Baja 650. then I put ARCO gas 91 octane and then all those quads smoked me. does gas make that much of a difference? by quality I mean.

thanks that really helped. I'm just gonna clean my carbs and run abgas since it runs better with that.

i put 110 octane race fuel in my banshee. I never tried it before. I ran it 40:1 with 2R yamalube and it ran like crap. when i got home I noticed that there was a lot of oil build up in my carbs. does anyone think it was the fuel or something else?
