Your the winner. Yes i found someone to fix it. Tge valves were tight. Apparently with a massimo the get tight all on their own.

I have no idea what that means. Massimo needs a Delphi code reader. The guy that was working on it is at a lose. He doesnt have a code reader and will not spend the kind of money they want for one. Now it won't start at all. It's getting to much fuel at start up. The whole throttle assembly, the injector has been changed.

Yes it is.

This is the only problem I've had with it since I bought it. Yes I talked to Massimo they said sound like the fuel pump but one shop said they tested that and it was fine. The second shop had it for 5 weeks and never called me on it or even worked on it. They wouldn't answer their phone or return calls after I left messages. But when I dropped it off the guy said it sounded like the mass air flow.

My 2013 500 will only start if I floor the gas pedal and then once it starts I have to pump the gas until it warms up a little it sounds horrible until it warms up.(around 20 seconds)and then it will stay running. The exhaust smells like raw gas for a little while. The throttle body has been changed. Someone suggested the mass air flow sensor could be the problem ( is that the MAP). It has been to 2 different shops with it not being fixed. I haven't been able to ride it since last fall.Does anyone have any suggestions?
