CJ-
That sounds just like what I need.
As for spark arrestors and registration, I live and ride in NorCal where the dirtbikes must blow cleaner and quieter than a fresh summer breeze tickling the redwoods, lest the Sierra Club extort our governor to close more Forest. Frankly, I'm on the most politically correct dirtbike (oxy?) available, a Green Sticker KTM 400EXC.
Regarding "roping me up", I thought that was a Texas thing and you Colorado'ers were a little uh, North of that kind of behavior. Having lived in NM, I know!
Thanks for the info!
