Grant, We were talking about this at the track- This excerpt is from the 2002 online F-RD rules. I think in previous years RZ boots were not allowed. IMO, the RZ boots and crossover do such a good job getting rid of the stutter spot in the carburetion, they should almost be required as a safety item. They keep people from wanting to lean out the bike too much to aleviate the stumble. Therefore the correct main can be used on top end for good power and some safety margin against seizures. REED VALVES: Stock cages. Aftermarket petals permitted, openings may not be enlarged. Rubber boots may be substituted with RZ boots. No spacers allowed.
