Bike went away last fall totally fine. This year getting ready for the season and I have no injector pulse to cylinder 4. Checked everything and there is no signal coming out of the computer to fire the injector. If anyone has a spare ecu that I could even barrow just to prove it before dropping big money on a new computer or if anyone has a spare ecu that I can have for not huge money. If anyone can help me out I will forever be greatful. Thank you guys again!
