Hey guys, I've been playing with valving on the 02 cr 250 for about 2 years now, and feel that it could'nt get much better than it is now. Very well balanced and most remarkably is how the front follows the terrain. Stock the bike deflected alot almost to where a fast hit to the front would bring the rear around, and the rear would deflect on acceleration just didnt seem to track well. I revalved with racetech front and rear, but used stock springs at time they spec'd to my weight. Shock was never a problem since, but the fork still had issues. After countless valving issues heres what i found. 1. I quit smoking the day i bought the bike, +30yrs, = additional 20 lbs to my chassis. 2. resrung bike fr&rr. Racetech said Honda rated .44 was innacurate, .44 was what i needed, I purchased new .44 springs and there was a significant improvement in ride height/bottomming resistance. 3. front end still felt harsh on small bumps, changed inner chamber springs from moto-pro, big difference here guys, small bumps good bike started following terrain. 4. Bike blew through stroke after initial revalve, Racetech recommended removing mid valve, I feel this is wrong, it puts all valving on the base valve = harshness. Reinstalled stock mid valve bike had bottoming resistance back. 4. after installing mid valve revalving of base valve was done, i actually made my own base valve shimming to get it just right. 5 I revalved rear shock softer than racetech specs, I feel that the forks now work so well that the rear shock was stiffer to accomodate for the origanal mistuned forks. 6. Conclusion, verify proper springs, change inner chamber springs, revalve bike. I have gold valve specs, other valves you would have to tune and figure your own valving, just dont think oil will get you there, since i have been through this.
