Hi, I have a 2002 yz250f and its a mutha er to kick over. I was told that installing a '03 or '04 cam and a valve adjustment will solve the problem right up. Sooooo any feedback or know of a place where I can get a Stock cam for this year ASAP. E-bay is not helping me. I live in Los Angeles and am anxious to get back on the trails! Thank you.
