how do i increase top end

just fyi top end isnt the same as top speed...top end is how much power you have at higher revs....bigger tires and gearing changes how much torque you have at the wheels....for top end get a hot cam stage 2 and a sparks x-6

Correct, if you were road racing the gearing mods would make a difference, but that has litle bearing in off-road.........about the cam........read my reply in the "few questions" thread
