I just rode my 2011 800 etec summit for he first time with perks spin balancing kit installed on it
"WOW" engine is amazingly smooth now no vibration in the running boards (air Frames) or handle bars
there's a slight vibe as engine is coming off of idle 1800 to 2500 but not bad at all Less than stock
once sled is moving its really smooth, watching the clutch when its running it doesn,t dance around anymore its very concentric
switched back and forth between mine and my buddy's 2010 summit x night and day difference his vibrated almost the same as mine before
I can pull 2 more grams of weight in the primary on the same clicker # just from the balancing & install was Straight forward about 3 Hrs
This is the Real deal !!! best $350 ive spent on my sled
