Starting immediately after the mandatory 600 mile service check by an authorized KTM dealer, this vehicle started experiencing prolonged cold start failures. It went from starting 100% of the time after three or less start attempts to requiring approximately ten failed start attempts before starting and running. Until 10/20/21, this motorcycle has always been fueled with either 93 octane gasoline with 10% alcohol or 90 octane fuel with no alcohol (only 2-3 times) as recommended by the manufacturer. On 10/20/21, I filled the nearly empty fuel tank with 87 octane, 10% alcohol. On the next overnight cold-soak starting attempt, and every cold start following, the vehicle started immediately on the first start attempt and settled immediately into a normal fast idle until warmed-up. This vehicle was purchased new with 0 miles on June 11, 2021. It received it's 600 mile manufacturer-required service at approximately 680 miles in September, 2021. It currently has, as of 10/24/2021, approximately 1300 miles on the odometer.
