Cleaning power valves too often

Just got a 02 zr 800 and but on about 75 miles and it started runnin horrible could only go 30-45 so i took it home and cleaned the power valves put in new plugs and it ran great. took it out again after another 60 or so miles maybe a few more bam same thing happened so i rode it home again going 30-45 miles and hour cleaned the power valves and got to thinking that maybe they put bad oil in it so i drained the tank of all the old oil and put in a quart of amsoil intercepter but haven't run it since being theres barely enough oil in it.

Is there anything else that should be done or would be causing this problem? any comments would be helpful and if you need anymore info i may be able to give it to you.

What did the Valves looks like when you pulled them after cleaning ? Whas there an essesive amount of oil ? Lots of carbon Build up on the valves ? Also must make sure they are perfectly clean or the valves will stick.

While I noticed a big difference between Arctics APV oil and the
Interceptor oil, I would think there has to be something else going on if they need cleaned that often. Didn't some of those power valved ZR's have wear issues?

well the second time i cleaned them when i took them out there was some oil on them but i'm not sure what excessive is being its my first power valved sled there was a little carbon on them but not as much as the first time i had to clean them.

as far as oil our arctic cat dealer told my dad that the intercepter oil is better and cleaner than the arctic cat ( just what the dealer said i don't want to start an argument on it) and as far as wear issues i'm not sure on that

but i have no idea what kind of oil was ran in this sled before i purchased it or what was in the tank and it doesn't seem to be burning to much oil

Thats what I am thinking. Those Cable have to Be perfectly adjusted to the correct lenth and Both the same. Not sure on the measurement for the cables on the 800.

but when it is running good for those few miles that i have gotten out of it it runs like a top, keeps up with my dads crossfire 800 H.O. (keeps up doesn't beat it) but it does have some clutching and speedwerx head with the trail inserts not the domed inserts. thats why i wonder how the cables would be out of adjustment but i'm not an expert on these power valves

does anyone have more info on what cat-sass is saying about the wear problems? or if there is a common place for them to be hanging up? also if the sled would run so good if the cables are out of adjustment?

Sorry I don't have any specifics for you, I'm just seem to remember seeing a post or two regarding problems with some sleds of that era.

Does the performance seem to get progressively worse? or does it come on all at once?
Are you working on it in a heated shop? Any chance there is water in carbs/filter/tank that thaws while sled is in shop, then freezes after a time out in the weather? The first time it happened, you changed the plugs, how did they look? Black, brown, white?

The wear problems are on the pin holding the valve. But if you had problems with that, your rings would be hitting the valve and take out the piston...

I too will guess either a servo or adjustment issue. Use a micrometer to measure the length of exposed cable on the servo end. It should be between 1.17 and 1.24".
