Motor was pressure tested, 5 hours break in and broke in similar to forum recomendations, reeds are brand new, cant remember what head gasket was used, pipe is stock and sealed. Bike ran the same before rebuild. With fresh plugs will start first kick cold with choke and clean up and run. After it gets warm low speed trail and or short idiling will cause it to load up severly and will usually clean out and run. Other times will bog, back fire and die and its over. Plugs BR9 NGK, if there is anything I left out that might help let me know.
