Ok so my son started racing last year so my bike has seen little action. I pulled it out this month and it will not start. Has spark . I took to local dealer and they found the same thing has spark. Told me to start with replacing fuel pump then injector if fuel pump doesn't solve it so I took the bike home. Fuel ump $400 after taxes expensive test. I was thinking that when I take it to a Yamaha dealer they would have the proper tools to diagnose my bike so I am 145 out of pocket and back to square one..
