Help with an 02 919

My 919 wouldn't start. It sat for some time just because I did not have time to ride it anyways. The dealership just checked it out and says the ECM is bad. They said that the injectors needed cleaned (which I don't doubt) but the ECM is going to be like a grand or something. Help!

You can check the dealership's story by trying a known good ECU on your bike. If it runs with your buddy's ECU, but not with yours, you need a new ECU (or a good used one). It's not a big hassle to swap ECUs with someone, if you can find another 919 owner who wants to help you out.

ECU's rarely if ever go bad...

The 919 needs a good battery that will hold a charge first & foremost and if they can't get it to start they won't know if the injectors are bad or not as I guarantee they haven't pulled one & looked at it...

Again though ECU's don't just go bad unless they tried to hook up jumper cables from a car or truck that was running etc...

ECM's typically don't go bad from sitting, unless the bike was underwater. What does it do when you try to start it?

I second that. Did you do anyting with electricity that could fry it. Jumper cables backwards, welding, use it as an ancor?

Bikebandit shows $858 for the price. Thats alot. I'd definitly try to find someone that could swap with you to be sure first. Doesn't cost anything to try, unless of coarse you fry their ECU.

Mine was sitting for 15 months after it was crashed.I put a new battery on and a gallon of fresh petrol and it started straight away and ran lovely.Seems strange that the ecu appears the cause.

I bet you a doughnut if you put in a fresh battery it will start.
