It has been bugging me for a while and i cant figure it out at all, i bought a new carb, new CDI, new coil and it still acts up. PLEASE HELP!!!!

Did you ever properly adjust your rocker arms? They go out of adjustment in about 500 miles. Also the jam nuts can work loose and the adjusting rods start backing out. If they get really loose the motor will idle but dies when throttle is opened. Check that out and post your results.
