I have a 2012 super 8 50 2t and at the moment it's my primary mode of transportation. It stalled a couple times while driving it full throttle and now I cannot start it. It "cranks over"....but won't start. The gas is good, fill the tank every week with ethanol free gasoline. I changed the spark plug and cleaned the air filter. My next step is to check fuses than check to see if I have spark. Any suggestions/advise? Thanks!
