I have a 1988 zilla that is stock except for fmf pipe and silencer, v-force delta reeds, and a 39 pwk carb, I am trying to figure out what size and how many paddles a guy should use for sand drags and hill climbing. Skat trak says to use a 20 inch tall tire with 8 or 9 paddles. someone out there must have a good tire combination figured out. I used to have a honda 250-r and it didn't like to pull 20 inch haulers in six'th gear to well. Has anyone ran 22 inch haulers or tried the new extremes?Any help would be apprecieated.
