I took the bike out of winter hibernation yesterday it has always idled at 1000 rpm. when I started it went to about 1200 rpm and as it was sitting there it was slowly climbing. I thought it was because it was cold. I got it in the garage by now I could feel the heat coming off the engine. I gave the throttle a quick twist. nothing. I shut it down for a bit then starter it again and the same thing at about 2300 rpm's I shut it down. can anyone give me a starting point of what to look for?
