am wanting to install some hi comp pistons on my 07 warrior. current mods are
cIII, vance & hines pro pipes, k & n filters. want to know if i will have any problems after i install the pistons due to the 10.2:1 rated comp. i have tried 87 oct. fuel but runs better with 93 oct. i have raced a 1200cc sportster with the screaming eagle package and had to ease off the throttle in between gears so he could keep up but was disappointed once i reached 4th gear. i did pull away but not like the 1st 3 gears.....
