Hi all
My bike is a k7 twin spark 650 model.
I have the f1 warning light coming up showing C 40 which is the ISC,idle speed control valve.
When the bike has been stood for a few days without been started the bike starts and runs rough I turn the engine off after a minute and back on and the problem has dissapeared and I can go out for the day on it without further problems.
I would be grateful for your ideas and thoughts, could it be the plugs need changing? they haven't been done for a long time maybe 18,000 m !
Also can someone tell me if I need four of the same spark plugs or are the top ones different to the bottom ones?
