1. xr200r is not a desert bike.
2. high altitude messes with your front forks. bleed/check pressure, when changing altitude. maybe I'll take out the valve cores the next time I have to take the bike over a pass.
3. high altitude messes with your tire pressure. check pressure. it was way too high in the high desert.
4. deep whoops in sand suck, see #1
5. steep hills with sandy soil suck, see #1
6. have fun, don't worry about the sweep riding behind you.
7. having an old style seat (i.e. nut crusher), allows you to tape the route sheet to the tank.
BTW, I managed to lose one of the sweeps in one of the canyons. I ended up going off course to follow the creek bed a little higher to avoid the sandy hill, before cutting over, and he must have gone back when he didn't see me on the course anymore. at the next check, they were asking me whether I had seen the sweep, me being the last rider on the course and all...
I wish it was easier to post photos on here.
