seeing as I always ride the same place, I have the same routine. Start it up, let it sit for a few minutes running. We coast down a half mile hill from camp, hit a flat spot that's about a mile and a half long, through there I ride it slow and easy in third. From there I pick it up a bit and always hit the same short hill climb and clear it out some. By the time I get to the first long uphill, the bikes warmed up, and when I nail it she sounds like a chorus of finely tuned kazoos, and it pulls hard once on the pipe...yahooo! This to me is about a fifteen-twenty minute warm-up.
It took me some time to figure out how mine likes to run according to my set-up, but if I jump on and wind the piss out of that little motor any sooner, it has a limited and scratchy response.
