Mine are almost new Sprockets. Stock is 13/50 I am running a 14/53, same ratio but should improve life. I guess my question on sprocket would be isolated to this area. Should I drop a tooth or 2 for a desert scrambles. and should I stick to a 19/90/110 rear tire. Also air pressure issues. I run 12 pounds in both. Local set up issues and such. Also what to expect on race day. Maybe I can email a local motorcycle club.RidingTheRockiesNeed to change sprockets? Guess that depend on how yours look. If the teeth are worn might be a good ideal. How bad are yours? If you do change spockets change the chain as well.
Thanks sully and Rockies. I got a copy of the rules and left an email for the captain of the250 class for district 38. Any tips you can pick up on the 11th ,tire size etc would be appreciated.csullyi don't know where you'd find info on them, other than the AMA site...although, my brothers and I are checking one out on Jan. 11th in Spangler (near Red Mountain in the Mojave Desert...District 37)....maybe i can figure some stuff out for you...haha
i'm not sure the best tires to run out there for a scramble...but in the desert we keep the pressure pretty low 12-13psi; and use heavy duty tubes...some people don't like them because they make the tired heavier...i'm not really sure if they're beneficial in a scramble or not...but for the longer races, definitely.


You can do one of those Tonya Harding tricks.csullyyuck yuck yuck. so funny woodsy ;)yzwoodsJust don't try it on a quad Court lol :)
hahaha.....who knows...we'll see


Hey Dag have fun! The sprocket thing doesn't really matter at this point in your racing career. Once you race your first time, you will know if you needed more speed or not. If you can go 75 mph (top speed) you're fast enough for now. Some-times the hare scrambles have some gnarly hills to climb, with lots of rocks. If you geared for speed you'll regret it in the technical sections. Court is dead on about the heavy duty inner tube. Your chances of getting a flat are greatly diminished with one. Go over your bike really good! Tighten all your nuts and bolts. Of course your air filter should be clean! I bought a second air filter I keep handy for race day, because you'll be riding a lot on Saturday (I assume). If you go out on Saturday, you can fine tune your bikes jetting. I like to run my bike slightly rich on the main jet during a race.daggitMy bike can't compete with the 4 strokes in MotoX (neither can the pilot), And desert racing ffor 100s of miles is also not the bikes strong point. So Desert Scrambles seem to be a match. How do i get information on hare scrambles, Is there a site. I have been to AMA district38 site,but I want a idiots guide to hare scrambles. That covers prep to finish. The bike is a cr250
Wow, if your doing 70ish at 1/4 throttle you're plenty fast! Yeah, stock gearing is where I go for the desert. My top speed with stock gearing is 92 mph. Tire size, I don't know. I just like to have good tires. If it's rocky, put a little extra air in your tires, or you might get a flat or ding your rims (like mine). I run 12 lbs in the front and 14 lbs in the rear. If it's sandy I run 9 lbs in front, 11 lbs in the rear. The most important thing you can do in the desert is run the heavy duty tube. What area are you riding in? I've ridden just about every inch of the Mojave desert, and there is such a wide variety of terrain, but maybe I can help you out...daggitPaul That was great Thanks, What about tire size and pressure? Also I have taken my bike to a dirt road and really reved out each gear, I didn't get past 1/4 throttle. lol It is a 5 speed and in fifth gear it was flying ( I would guess 70ish) and had more to give when I let off. Still about 1/4 throttle. So for me the top speed is there, so the sprockets at stock work fine.
