Hey guys, great forum. I recently purchased a 2008 crf250r. I put in a new piston and replaced the valves with stainless. Finally got my timing set correctly, thanks to everyone's help. Now I just need to get the carb. problems worked out.

Right around 1/8 to 1/4 throttle the engine runs horribly. It runs great at lower than 1/8th throttle It runs great at greater than 1/4 throttle. There just one spot that if I hold the throttle in this position, it blubbers and runs like crap. Any suggestions.
