My horn is connect to my tach!?
Ok, I've owned my '05 SP2 for about 4 months. The tach display has always jumped forward when running. So if I hold 4000rpm, the tach will jump forwards, then back to 4k, its all over the place, by 500 - 1000rpm. It never goes backwards. I've check and greased the connectors involved in this circuit. Didn't make any difference, I just assumed the tach display was dodgy. But today while riding I used the horn, and the tach display shot forward into the RED zone. So every time I activate the horn the tach display will shoot forward until I release the horn. I will not do it if the engine is not running.
I'm thinking the signal from the ECM is getting interference by a dodgy wire or connector?
The bike has been down on it's side (left hand) at some stage, and is running a PC3. It is still the same the the PC disconnected
