I have a 2001 YZ 426 supermoto that will not start. Before I deployed for 3 months it ran fine, but when I came back it doesn't wanna start now. I put premium fuel with stabilfuel before I left so I thought it would be good. This bike has a brand new plug, carbs been cleaned, new air filter. The spark is good, the fuel delivery is good, and the air delivery is good. Any suggestions? I'm thinking maybe something electrical, because I tweaked with the wiring a little bit because it has the baja design street legal kit that wasn't wired properly.
