aprox 2 miles from home last night at aprox 5000rpm i heard a bachfire i believe through my exhaust , only once. immediately lost almost all power and revs went way down, in order to keep momentum up to get to nearest road i increased throttle with no results,the orange warning light to the right of high beam blue light began flashing ( this is not oil , or water temp light, i think it is computer or firing circut light?? i made it to the road after aprox 1 minute of this condition. the instand i let off the throttle and allowed the engine come back to idle the problem fixed itself. no abnormal engine noise at idle , i pulled away and everything worked as normal for the last 1.5 miles home. my guess is the spark circut , or throttle position sensor acted up. does the on board computer record when the orange light comes on? anyone ever experienced this condition?
sled felt like it was firing on 1 of the 3 cylinders ??
