What knd of times are u guys turning and what mods are done? I turn 4.8s in 300ft on dirt. Cpi inframes, ported, stock carbs bored to 28, +4 swingarm. Maybe some 4.7 or 4.6 with some v-force reeds, 34 carbs, and a little bit of fuel testing ;)

I have ran a best of 4.41 @ 72 mph on sand and 4.50's on dirt in 300 ft. I have a GRR 350 stock stroke, stock bore, no welded transfers, no triple exhaust, 34 mm mikuni's with GRR drag pipes.I run alcohol. It is a GRR chromoly chassis with a plus 10 arm. The bike really hauls ass in the sand. For the coming season I will be adding NOS. I hope with some tuning to run 4.teens or so.
