Well i have a 2000 polaris xcsp 600 that has about 2500 miles on it and i havent cleaned the exhaust valves yet. It runs good but has lost a little response , but how do I take these out and clean them i see there are 4 bolts holding a plastic cover on but below that there are 2 bolts that may need to go also well any help will be appreciated

 

Not sure about Polaris, but on a Cat you remove the 4 bolts and pull the valve up out....clean with steel wool and brake clean. Mine start to stick after about 500mi.

 

Snowest forums are as good for snowmobilers as this site is for Dodge trucks.

I used to pull the bolts out and scrape the carbon build up with a razor blade. The gaskets are made to be reused.
