So, I got 46 miles on my 15 XP1K. Just been plowing and doing ditch riding with it and haven’t had any problems. Today I took it up on the road and gave it her the nuts to see how fast I could go. Well, at 50-60 mph the engine surges/misses. It’s inconsistent and kind of feels like fuel starvation. It only does it when I’m on the road under WOT. If I’m in the ditch riding through the snow at WOT it doesn’t do it.

Anyone else have this issue?
