Bill, your class structure makes way too much sense! Simple, clear rules, a reasonable weight break for the motos, I can’t find a single reason not to adopt it.
I’m giving serious thought to puting together a stock moto package for Greg. I think we can get an honest 38hp out of one that will just last all year long and with a well set up kart, we could give many of the S1 karts a good run.
