WE-1200-KIT. This kit is for all 3 valves!! WaveEater-Wave Eater. Designed as an added measure of security when retaining the OEM Powervalves in Yamaha engines. Fitted clip prevents pin for moving and valve from dropping to low into valve guide. Special couplers better synchronize valve actuation through tighter tolerances and improved design. Instructions: 1. To remove the original couplers pull the black plastic clip off of the power valve shaft. We will not use the black clip when installing WaveEater couplers. 2. Push the coupler forward and pull up and off. 3. Install new WaveEater Coupler Slide on the small end of the spring then the stainless washer. The washer keeps the slotted shaft from spreading apart. Push the washer and spring on as far as it will go. Next, angle the coupler and slide on the flat end of the coupler over the long slot in the power valve shaft. 4. Line up the pin with the mating shaft and slide the WaveEater Coupler back into place. This will be a very tight fit and may take a little force to lock into place. The spring holds it on.
