Took a ride on interstate for about 30 miles on a 90degree day and rode about 80mph mostly in overdrive. Exiting the ramp the bike just dies. It restarted fine but would instantly die. It almost acted as if it was on choke (if it were an old carb engine) It wasn't missing or running rough at all at speed. I could be doing 60mph and pull in on the clutch and it would die instantly. After reaching my destination and parking it in the garage I rode back home 2 hours later and can not duplicate the problem. It also seems to want to do this when I leave work after the bike has been sitting all day in the hot sun on very hot days. Starts but will not idle and sputters until you get going. Any ideas? It has good gas, Techron regularly, is tuned up and runs great otherwise.
