Ok Friday night we started riding the grizzly and road it all weekend long with no problems at all. Sunday morning it decided to loose power, spit and sputter, and backfire. I wasn’t able to get above 15mph. Normally we run non-ethanol fuel in all our bikes, but I was unable to find it so I got 93 octane. Could it be the fuel? Does it have a limp mode if so how do I get it ou?
