i was wondering what kind of pump fuel i should be using? what type of oil should i be using? also i don't like the way the rear tires are so big compared to the fronts, so what is a good combo of tires for grass, dirt, rocks, ruts, and of course mud? please include sizes too please. finally what r some MUST upgrades to get my fourwheeler running nice and ready for riding? thanks alot!

 

anyone?
