the statement that gets me is, "were done! switching to bikes! selling our quads."
why???
you spent the money, have the quad, have the spare parts, why sell out? then why complain about how much money you lost? keep the dang thing and race it locally, heck, it's been stated several times that the base starts at the local track. bikes are cheaper to buy, so even for a working class guy it's not that big a deal to keep the quad and pick up a used dirt bike and race both at your local track. trust me, I'm not a rich man and have been able to keep a fleet of quads and bikes.
as far as cvt versus shifters, again, I paid for my cvt's and I'm gonna race them until we age out. I also run a shifter. yes, we all know at some point you have to shift, so it's not that big a deal to pick up a used shifter and race them both. again, I'm not a wealthy person. the wife and I both work and give up on things for our selves so as the kid can race.
racing of any kind aint cheap so stop griping about cost. heck, have you ever priced a top of the line BMX pedal bike? it will blow your mind.

and if you are a quitter, so be it, but no need to be a loud mouth and distract any possible new comers to our sport.
nothing worse than hearing, "we love it, but screw it, were out"
shut up and race or shut up and stay home, either way, unless your promoting the sport, just shut up.

and one last thing, for you guys who think you can switch to dirt bikes and lay around in the pits instead of working on cvt's. just wait, those little ktm's and cobra's are just as big a pain in the butt and will still cost you a bunch of money. been there done that.
