Some of you might recall my issues with the left and right acerbis petcock levers pointing the opposite way when off or reserve. http://www.advrider.com/forums/showthread.php?t=550703 Well I decided that the problem could be fixed. 1st unthread the plastic strainer from the left valve body, grasp it with your fingers next to the body. Then pull the long tube out of the body and insert it to the other hole. The front opposite of the barbed fitting. Ok now the easy part is done. Now remove the two screws which hold the lever retaining ring. Pull out the guts. Sorry for the lack of pictures next, but take the valve guts and use a dremel tool to cut a grove in the body this new grove will allow you relocate the lever 180 degrees. You can see where the old grove was. It's the area with the filled in epoxy. I cut the new grove first, also roughen the original grove to give the epoxy something the bite to. Once filled in and allowed to harden overnite the valve was sanded with 220 dry sandpaper and worked down to 600 grit. Place paper on a flat surface and sand the back side of the body. Make sure surface is free of any voids or scratches. Before putting petcock back together sand off the "OFF" and "RES" letters from lever retaining ring. Then w/ a dremel engrave "OFF" and "RES" in the new locations. Put valve in body, then spring, and place lever on valve 180 degrees out, place a little blue loctight on the two screws for the lever retaining ring. Then tighten up the lever retaning ring.
