Hello, new to forum. Got a 08 that is stock. Ran like a bat out of he'll for the weekend. Brought it out few days later and while riding I experienced loss of power, but of back fire and it died. Let it sit for a minute amd it started up and idled fine. As soon as I started to give it some gas and release the clutch an it died. Changed oil and oil filter. Flushed coolant and gas and am currently waiting on a fuel filter conversion kit to come in. In the mean time, I have run it (resting lifted on atv jack) on 5 occasions and each time it sputter and dies at the 10 minute mark. Anyone know what might be causing this?
