Just curious. I am in the mood for a little more up top. I recently installed a cylinder works 468 kit, I know it is not much of a hop up, but it pulls a little harder thru out the gears. i love the snatch of 1rst thru 3rd, and was wondering if i replaced 4 and 5 with the WR, would it drive out a little longer from the longer gears and is the tear down be worth the effort. 5th gear tends to be a little jumpy, so i need to possibly change that one out anyway and i thought while i had it tore down......what the heck, throw some WR into the beast and see what happens. Does anyone out there have an opinion about this?, has it been done before?, and what are the pros and cons if any?. lastly- if i have a 10 yz, what year gears from the WR will work? thanks thumper buds!!
