it could be any of several could be an intake leak, problem with the charging system, problem with the fuel system or a problem with the electrical system.I would recommend the following:- measure the battery voltage under the following conditions:ignition OFFignition ONwith the start button depressedwith the engine at around 2,000 RPM (fast idle).....let me know what you find and I can help you diagnose any issues with your charging system and battery.- check for intake leaks by spraying carb cleaner on your intake seals with the engine at idle. you will know right away if you have a leak........replace any leaking seals.- check the electrical wiring for pinched or damaged wires.- if nothing is found up to this point I would take the bike in for a fuel pressure check.....correct any low pressure issues. let me know if you need more help.Steve
