90cc clutch spring help

[jaketruck]

I have an arctic cat 90 two stroke atv. My kids ride in the hills and trails and I ride with the littlest one on this quad. I am trying to learn the ins and outs of clutch and clutch spring modifications to make the atv better in the hills. It is sluggish up the hills and also lacks "out of the hole" power. We have a 50 with a 70bbk and it smokes out of the hole. How can I help this 90 out?

Lightening the clutch or stiffer springs may help with the holeshot. The link is about lightening the stock clutch shoes, the vid shoes spring installs and a little more info for getting the best takeoff.

Lighter rollers or sliders would keep the revs up more and may help with the hills once you're moving.
