well you have to take the bolts off of the cover and you can pull the p-valves out. if there is carbon build up you need to remove it. I have used everything from oven cleaner to a dremall tool. hope this helps.

yeah you have to clean all power valves. at least you should. if you have an owners manual it tells how to adjust the cables. If it doesnt move easy inside then its not clean enough

I cleaned mine the last 2 years and it didn't need it at all, they were sliding with out any drag at all. You have to take off the covers and then there are 2 metric allen head bolts, remove those and pull the valves out. I used carb cleaner when i did mine.

You also need to shim the valves so they do not contact the pistons. Check on arcticchat, there is a post pinned in regards to this.

They stick which will give poor perfomance and makes it a pain to get them out.

Mine is kind off the same way, it takes till about 20 mph for the thing to start tearing. Mine is an efi but when it is really cold out it has a bad bog till it warms up. Also these clutches are in need of rebuilding around 3500 miles i've been told.
