Leave the variator alone but be able to go up hills, and whatever other functions that I don't fully understand yet. Had to deepen one of the holes, drill press then matched the hex pattern using a dremel. Then bolts right onto to stock case set up.

It's pretty nice for super takeoff, but fitting it was a little bit of a pain. I had to get longer case bolts to make it fit, and my exhaust mounting got in the way of it too.
Makes my bike do wheelies when I pop it into second though, and that's always a good thing.

you put your foot on it. and blast off. you hold it down and the motor stays unvariated, ripping up to killer rpms. then you can either let it out slow, and pretend you have a cool variator w/ light weights, or, my faaavorite, pop it and shift like an angry twospeed.
Win the uphill battle
