i didnt know anyone even ran regular in these machines to begin with...i alwasy run 93 on a stock motor, and the only thing that warrents high octance fuel, is more compression, ( milled head/cool head with smaller domes)
run 93 anyway, it cant hurt

theres less water and its more regulated in the premium fuel tank ... you should use regardless of mods IMO ....and i would run a b8eg platinum plug ,dont run irridium plugs -they suck balls .you will gain 5-7 % more by running race gas instead and 10-15% by running alcohol instead of gas

i have never had a problem with regular unleaded it still makes alot of cmpressoin and alot of kick back and i think my head is shaved too not to sure have too ask my dad

i would run 93 but premium is alot of money for a gallon as it is and 93 is more money and i cant be spending money on gas all the time i got stuff to pay

well, gas doesnt make compression sorry, you run higher octane gas on a higher compression motor...if your head has been shaved you would definatly need to run at least premium...most quads even have a sticket right next to the gas tank that says premium only, and thats with low compression stock motors..premium is only liek 30 cents more a gallon... u really cant spend the extra $1 per tank of gas?
