Bikes an '08 GSA. Strange issue yesterday - started bike up and rode 15 miles to refuel. Then a 50 mile motorway run to my parents - all good so far. But when I restarted the bike after a couple of hours, the throttle was surging independently of the twist grip. The idle was high and the revs would go up and down between 2K and 4K. Had an interesting time getting to the local hospital (not for me - just visiting) having to feather the throttle using the clutch and rear brake. After leaving the hospital the engine was still cold and the surging was continuing however, once the bike had got to normal temps the problem went away and was running as per normal.
My first thought is the splitter box and a sticking cable but can't understand why it would disappear when warm. I haven't had the tank off for a while and the cables are routed OK at the throttle bodies. I haven't been inside the splitter box yet - should there be a need to lubricate at all?
