i just built a new bike. i got the carb tuned somewhat and it idles great but im chasing another problem. the engine fires like a champ easy start and idles well but at the top end the engine bogs down i have moved the little retainer pin on the needle to several different positions and nothing seems to change i thought maybe it was eletrical like the plug wire was vibrating off at higher rpms so replaced all that but still bogging down. im kind of lost on this one so any suggestions would be greatly apprecicated thanks in advance
