Whats up guys! New to MX bikes. Only been riding for about a year. Broke my heel last Halloween at Ocotillo on my 04 CRF450R (now gone) New to the forum, I now have a 04 RMZ250 "race" prepped bike I got less than a year ago. By race, I mean it has some suspension work done, and apparently it had some mild engine work done at the end of last year (new top end: piston,rings,hone, clean up (polish)head/valves,rejetting) Has a FMF factory 4 pipe. The bike runs great when its running, but I've been having some issues with it on hard starting. Reading some of the threads on here, it looks like I need to check the valve adjustments (dont think it was ever rechecked after the rebuild, it had only been ridden once before I got it) Its to the point it is almost impossible to kick start it, but it will bump start after a few tries. Its ALOT better after its warmed up, but if it cools down, its a pain again! I'm going to pull the carb and check the jetting/adjustments. And I want to check the valve adjustments. Sound like a good place to start? The bike used run real warm, found it was extremely low on coolant so I put in EngineIce (works awesome!) Has a Boyesen waterpump kit also. Any tips/suggestions on jetting and maintenance will be greatly appreciated. Thanks!
