i love my rubi and she takes me almost anywhere i want to go, but lately i have seen alot of the kawasaki brute force 750's and 660 grizzly's. not that they intimidate me but they have alot more get up and go it seems like. it hasn't happened yet but i don't want to be put down by a kawasaki or yamaha. what are some things i could do that would not wear out my fourwheeler to give me a little more edge on these guys.

 

porting, pipe, tires,and bigger valves
