04 SKI DOO MXZ 600 sputters at 6000rpm

[boldmoves]

Any help would be appreciated on this. It runs nice and smooth, compression is at 130 and 132, cleaned out carbs changed coil and still spitts and sputters at 6000 rpm. Any Idea what else I could do?

How do your reeds looked all chipped?Take a quick look at your reed boots also might have small crack or delamb and taking in to much air ,running lean and ready to EXPLODE.

Sounds like a fuel problem. Dirty Carbs might be the case. Like Powderlsut says : check your boots and reeds. Is this the first you are running the sled this year?
