Power valves

[sledneck_03]

Sled has 1300 miles on. Pump is turned up and with lack of snow has came lack of drive and maintenance.

Wouldnt move with gravity. They were dirrrty.

Ahhh thats better.

Sleds only real hick ups a varying wot rpm. Did the doo thermostat and no real improvement. Hoping this as well as a primary service will solve it.

Thats new clean. What do you use to get them that clean

 

[sledneck_03]

-Orange engine cleaner.
-Utility knife
-1000 grit paper
-Gloves
-Drain pail
-Paper towel

Spray all down into pail. Scrape off with knife. Wipe down with paper towel. Scrape more. Wipe. Then use the sand paper. Then i sprayed them again and dried off with towel and what you see there is what i got.

Took longer to get them out of the sled.

That is one dirrrrty Valve-
I generally pull the valve and hit it with a wire wheel- clean in secondas and get the heavey's burnd oil odd in the areas where you generally have to scratch at.
I do mine twice a year- just for grins ( Stupid steering post anyway)makes it a bit more harder than it should....
I do not have my oiler turned up 1400 miles and waiting for the knife edge to make it a summer project for the "KIT"

We just cleaned our 2013 800 for the first time. Oiler is turned up 3 turns and the sled now has 3000 miles on it. Turned out it was a waste of time pulling them out. They were just fine. As far as cleaning, in the past I have use Dawn dish soap, oven cleaner and brake cleaner. Not all at the same time. Another trick, when scraping the valves off or scraping the old gaskets off I use an old plastic light switch cover. Can't damage the metal surface. The newer light switch covers are vinyl and don't work as well. $.02

Make sure the pressure port to the cylinder is good and clean too.
