I have a 2 stroke snowmobile with power valves. It's an arctic cat, and they recommend their APV synthetic oil. The previous owner of the sled always ran klotz oil, so that's what I've continued to run. If nothing else, it smells good.
I cleaned the power valves when I bought it in 2014, with 1200 miles on it. The sled is getting near double that now. Power valves are working fine when it's warm, but they're starting to get just a little bit sticky when the engine is cold. I may or may not clean them again in the fall.
Obviously, I don't like cleaning the power valves. Is the klotz oil pretty good, as far as that goes, or would the artic cat APV, or Amsoil interceptor, be better?
I previously had a 1300 Yamaha triple in a waverunner. I rebuilt it and ran HP injector. Power valves got gummy quick. One broke, luckily bouncing out the exhaust without costing me an engine, and I started running Interceptor when I put it back together. I never opened it up again before I sold it, and never considered cleaning them. The actuator forced them closed on the Yamaha, though, where the arctic cat relies on a spring to close them.
