If you’ve been putting off cleaning your Rave Valves (power valves for the former Yami converts), wait no more! Swiping a few tricks from Rev Baron and Gman, here is a way that is SO easy that anyone that can hold a screwdriver in their hand can do it. No parts to replace if you are nice to Mr. Gasket. This write-up is for the standard and HO engines, (slightly more work if you have a Powertek or SDI).

Step 1 - Using a 5mm ball end allen wrench loosen the two side screws that hold the Rave to the cylinder.

Step 2- Carefully scrap the green gasket off the cylinder with a plastic putty knife. It helps to start the gasket on the edge using your fingernail, then gently slide the putty knife under the gasket while pulling up on the gasket with your other hand.

Step 4 - For easy cleaning without a bunch of scraping and cussing, use oven cleaner on the Rave valves and let the cleaner do the work. I cut a slit in the bottom of a sandwich bag then slide the Rave in, valve first. Push only the valve portion out thru the slit. (Everything else is in the bag.) Put both valves in a small container, spray LARGE amounts of Oven Cleaner (lemon scented makes my wife the happiest) in the container covering the exposed portion of the valve. Now wait…several hours if they are not too bad…overnight if the are real bad. Wipe clean with a paper towel and a light rub with a scotch brite pad.

Step 5 - Reinstall valve and tighten screws until tight with your allen wrench ( shop manual spec is 7 foot pounds) DONE. Go ride and feel the power when those clean Rave valves open WIDE.
