Not really. It was above zero degrees, machine doesn't have DPM and Dyno-Port says to run stock jetting. According to the jet chart we were right on. Many dealers have no issue with pipe's as long as jetted. Remember machine didn't fail due to leaned out, but something messing up the skirt.oldslowsledder said:You post up about BRP reliability when your engine goes down, then after it's fixed ( by the way was it warranty?) inform us you made jetting changes and installed an aftermarket can and pipe. Seems unfair to call manufacturers problem, doesn't it???
