Here si the real deal. 04 ZX10, with power commander (map set for MR9 fuel), full exhaust. Just got bike out of storage, treated with fuel injector cleaner. I put VP U4.2 in the tank, kranked it up and it ran for about 3 seconds before it shut down. From that point on it will only stay runnning if I stay on the throttle. Obviously a big issue. I ahve no idea why.
