I ride an 05 CRF250R and mostly ride open desert/mountain single track, whoops etc. The bike had some suspension work done to it when my buddy owned it but was mostly set up for a 6', 190 lb dude. I am not sure if he mostly set it up for the track or not. I am 5' 8" and 170-175 with gear. I consider myself an intermediate type rider. I would like a better ride in the listed conditions. 1. General suggestions for desert set-up? 2. Should I change out anything or keep what I have and change the settings? 3. If keep what I have, what should I do? 4. If change stuff out, what should I do? 2. Can I do the work or should I take to someone? If take it, any suggestions for Las Vegas area? Thanks.
