My godfather gave me his 2006 Yamaha FZ6 and it had been sitting out in the weather for years. I drained all of the old gas and replaced it with new gas. I did an oil change and changed the filter. I replaced the fuel pump, all 4 spark plugs, ignition switch, and ignition relay. I did a compression test and there all reading between 120-125. I added fuel injector cleaner to the gas at the correct ratio mixture. I also set the cam timing to where it needed to be. The bike will turn over but will only fire if I use starter spray but it dies in the matter of seconds. What could be the issue?

sounds like something is gumming up the works if it starts with starter spray and then isnt getting the new gas. Did you ever find solution?

Yea the fuel pump I bought was a dud

Im glad you figured out the problem! Where did you buy fuel pump from? just curious because I bought a used one on eBay today.
