02 cr250 STRANGE PROBLEM????

Recommended Posts

well my bike when riding home from the mountain today started to get very poor acceleration to the powerband.it would literally take me 5 seconds to get the powerband in 4th or 5th. so i pulled over and told the guy i was with what was happining and i started again and it was fine. the bike wasnt loading up or blowing smoke when this happened just very power power delevery. i was thinking maybe the RC valve was the culperate. i also move the air screw out a turn or so prior to this. any suggestions????? thanks!!!!!!

Could be the clutch. Check and make sure the powervalve is operating correctly as well.

yea the clutch is great ive been there to when i adjusted the clutch to tight one time. is it possible for the powervalve to stick for a minute. maybe dirty powervalve or somthing. man i hope its not my servo motor that runs the powervalve. i jus replaced that part. anyways thanks.

take the cover off the powervalve and see if its opening and closing fully, if so your good... also check that the cables are not too loose
