My 636 only revs out in neautral. When i hit 9k or higher rpms my bike starts bucking really bad like fuel cut when driving ot in gear. If i put my bike in neautral i can rev to red line no problem. once i put it in gear even when stopped and clutch in it will miss at 9K. Cleaned air filter,replaced plugs,cleaned injectors everything looks normal and in place under tank. any ideas?
