Hey everyone. Im helping a friend get his bike going again. He was at the sand dunes and it started knocking really bad, but it was only ideling when it occured. Took it to a large dealership and they said the timing jumped and it would be $2,000 to fix due to "evidence of wear" on the lower timing chain gear on the crank. We picked up the bike and decided to have a look and the gear is fine. We removed the head and had a machine shop check the valves and do a leak down to ensure valves were ok. Everything check out with flying colors. We got a head gasket, timing chain, and tensioner and put it back together per the manual (not my first valve/top end job). The bike wont fire at all. It has spark (pulled plug and can see a good blue spark), disconnected the fuel line and kicked it and fuel is pumping. We cant smell fuel and i tried to look/feel inside the throttle body to see if the injector is working and it does not appear to be doing anything. After kicking it 50 times i would assume that the plug would be soaked with fuel, but its dry every time. We attached some power to the injector and can hear it "click". Im at a loss as to what is the problem. Any suggestions? Thanks.
