Working on a friends 07 420 rancher. It has set for along time. We have cleaned the tank replaced fuel pump fuel injector and fuel filter. Im getting fire with the a new plug and getting a good spray out of the injector. It will hit it just wont keep running if it does start. When i replaced the fuel pump we cleaned the canister and filled it half way with gas so it wouldnt have to work so hard on pumping full of fuel. I have never worked on a fuel injected bike before. So any suggestions or help is appreciated! Im learning about these things!
