So I recently went and picked up a 06 ltr450. Took it to the dunes this last weekend and I had nothing but problems. Would start to go and it just felt gutless. It also would spit and sputter almost like it was changing the throttle position by itself, I'd be almost full and it just cut everything and act like I wasn't even on the throttle. It got to the point where I couldn't even get going to get it back to my trailer. It got hot pretty quick so I was assuming maybe it's running lean? I'm just looking for suggestions I've already replaced the swirl filter with an inline filter because mime started leaking after this ride. It also has a pim and fimak and idk much about those so could maybe the map it's on be funky? Any suggestions would be amazing.
