Mate bought a 2010 c50 a couple of weeks ago with 20000k on it. We went for a 4 day ride and on 3rd day it lost power but idled ok the lower muffler got red hot in one spot near the rear end that it melted the baffle. Thought a baffle collapsed so drilled holes in front of it to allow exhaust to get out but no change. No oil smoke and both exhaust ports good clean grey to mild black colours . Tried to limp to a town and it eventually stopped and won't start. I am thinking ecu has shit itself. Looking for ideas as dealer is unlikely to be helpful as no warranty on second hand bikes in qld. Feel sorry for the poor bugger as it's his first bike for 25years and this happens.
