Has anybody had any luck curing the lean running condition these have? Ive got a 2016 dominator x4 800 and have had a lean running condition pretty much from the get go. Its all stock other than removing the catalyst in an effort to bring exhaust temps down a little with no luck. After even a short trip at 3/4 throttle or above the exhaust pipes will be glowing from the heads down for several inches. Condition improved slightly with removing the cat but obviously was not the problem. Im gonna slide a new fuel filter on and see if that helps any. fuel pressure is sitting a little over 50 psi which seems to be the proper pressure. Any other tricks out there?
