I have a 1991 K100RS with 36K miles. Living in Oklahoma I don’t ride it in the winter due to the ice. I keep it garaged with a float charger on it and start it up about once a week. Well, I tried to start it yesterday and it wouldn’t. It usually starts right up but it wouldn’t even fire….I opened the gas cap and the gasoline smells like it has gone bad. I siphoned all the bad gas out but there are still tiny gooey particles in the tank bottom. Short of taking it to the dealer, what exactly do I need to do to get it up and running again? Any help would be greatly appreciated!
