I have a 00 Yamaha XL800. Bought it at the first of last summer, rode all summer, no problems. The very last time I took it out, i lost all power and it would not start back. It will crank, both cylinders are showing "blue arc", the fuse is good, and the fuel filter is filling up. It sounds like it is "trying like crazy" to start, but it is just simply not starting. What is the deal guys?
