I put my 04 1300 up for most of the winter, rode a few times through the winter. Before it got cold it was running great, now I am having some issues out of it. It is having issues running when it's cold. Start to spi, sputter and cough. Now today it started to have a continuous popping and backfire until it got warm. I was thinking it might have some water in the tank because after running a tank of ethanol free fuel and some sea foam it ran great up until about 60 miles then went back to acting up again. So now I am lost. I have replaced the plugs and cleaned the air filter. Anyone have any thoughts?
