I am getting raped by yfz's and the like. my cousin has a 04 yfz 450 with a pipe, jets and k&n. he is on the stock tires and i am on maxxis razors. He simply destroys me even from a roll. He admits my banshee should beat his 450.
Specs:
Rebuilt motor with maybe 30 hours on it.
Trinity Powerflow Intake Kit
Trinity Stage IV Exhaust System
V-Force Reeds
Trinity Stage IV Standard Head
Dual Aftermarket Flatslide carbs (dont remember the exact size but bigger than stock)
no airbox lid
The plugs look great! Do i need different gearing? I am thinking of an adjustible timing plate for sure.
