Default Driver to small for 7” Driven

I thought I would add a 7” driven to the Kart for increased torque because of the big 22” tires and heavy frame. It works great however I am limited to about 3,000 rpm because the belt will climb above the small primary clutch. I should have thought about this considering an ATV clutch uses the same size driver and driven so they as the belt transitions between the sheaves it is taken up by the opposing side.

So, is there a bigger drive clutch? Has anyone used a 7” before on a 30 series’s day had the same issue? Even with the 6” why would they not make both sheaves the same size?
