Won't run

I have a 300EX and I just can't stop it from missing @ 3/4 to full throttle. I have tried to adjust the valves and nothing happened. (one thing i could think of was jetting but I've tried 3 different jets. I ride around 6,000-10,000 Ft. I have a K&N Air filter and a FMF Mega Max pipe installed. If you know or have an idea of what jet I should be using please let me know!~!) I NEED HELP!~!~! IF anyone has any suggestions on anything your feedback is greatly appreciated thanx.

it has to be the jets, since they control 3/4 to wot, unless u use the choke to sart it, then the readin wont be right

hey i noticed the pic of ben jackson and just figured that i'd say that he lives like 2 miles from me. just thought i'd share that with ya

What size main jet is in there now, and what size jets did you try? From the sound of it you might be too fat on the main if it "blubbers" when at 3/4 to WOT (blubbering defined as how the engine runs when its too rich such as when the choke is on). BTW, riding at high altitude typically requires leaner jetting, especially on the main since this circuit can't be adjusted other than the size of the main jet. You should also do a plug chop when at WOT and see what it looks like. If the porcelain is black/sooty it's too rich, white/gray is too lean, light brown is correctly jetted.

ben jackson is kool, i would check the jets for clogged nes

Try cleaning ur carb....?

Ive cleaned the carb and i put in a 118 jet (stock is 122 and high altitude is 120) the plug is getting toward the leaner( brownish white) side. Any other suggestions?
