Hi everyone, been reading these forums for a long time but have never really needed to join up. Great information all round.

I have been having some troubles with my 2011 Yamaha FX HO. It was running a bit rough so changed up the spark plugs and checked the fuel.

Was still running rough and have now found the throttle body remains closed all the time when riding. I plugged in a spare throttle body and the same thing happened..just wouldn't do anything.

Has anyone had this problem before? Any particular sensors to check before i invest in a new ECU?
