How often do you clean rave valves?
valves is not a big deal and should be done at least every 1000 miles (I prefer every 500 miles). Once you get the hang of it, you’ll find that this takes very little time. By doing it often you will also find that it will not only keep your sled running at its peek, but also aids in the cleaning the next time.

How often should you clean power valves?
I’d recommend cleaning after the first season; then either once a year or every 3000 miles or so. While in most cases you can get away with neglecting that, there are possible issues in doing so.
