You prolly have 4 rollers in there now.
Clutch mods don't work w/o a motor to turn them (For the most part, keep reading).
With no motor work you will go in the direction of gearing up to get speed. This is where the 4 rollers thing will help. The other thing would be to lower the weight of the 3 rear clutch shoes from 210 grams to 180 grams (each).
I'm guessing that you'll want a 12/13 front sprocket to go with the 22 rear.
"flat spots every 6 mo."
That's a lil funny. It tells me that your maint. schedule is non existant. This may work for a pure stock yard ride but not a dune/racer. I service my clutchs before every race or big ride.
I can do it in 10 minutes, you can too after doing it a few times.
