Yesterday rpms would not get above 4800, normally motor turns 5600,
Got home and found the top cylinder on the port side was not firing, Swapped a coil from a working cylinder as well as the plug from another cylinder, Still no fire on that top cylinder, So that eliminates coil or plug problem. Showing absolutely noting with my volt meter. I don't mind spending the money to have the Yamaha place fix it, Problem is it's 4-5 weeks before they can even get to it. Anybody got any ideals what else I could check. Thanks
