I just picked up a 03' with an estimated 20 hours. I believe the guy as the frame and everything looks great, but I'd like to get a compression reading for the helluvit. My 06 YZ250 pulled a 215lb reading after a fresh top end, which is great compression for a 250 and shows my gauge is in the ballpark. With that in mind what should I expect from each cylinder?
Stock motor, stock carbs, FMF fatty's and K&N's (no airbox) are the only mods. I'm at 300ft ASL.
Lastly, should the reading be taken on a motor at operating temp or stone cold? My YZ blew a 215 at operating temp and lower when cold.
