what altitude?

double check tomake sure the slide spring isnt cocked and not allowing the slide to fully lift.

spring is good im getting full throttle just seems to sort of spudder in mid range.i should be around sea level or a bit above, like a big hill would be 1000 feet here.

How long has it been since you put a new spark plug in the bike? Some times the plug can load up and not clean out until you crack it wide open. If that doesn't change anything try moving clip to 2nd position. That will lean it a little in the mid range rpms. Sounds like its running rich in the mid rpms.
