Some pics on how to setup the exhaust valves of your vj22 engine. 1) Turn the ignition "on". 2) Turn the kill switch to "on". 3) Find the "grey" wire that is located near the battery and most probably it's under the fuse box. Uncover the brass fitment and touch it to the ground terminal (-) of the battery. You should immediately hear the servo mechanism moving. While you are still keeping the grey wire on the earth terminal... 4) Turn the kill switch to "OFF". 5) Now, it's time to setup the powervalves. You should align the mark on the servo pulley to the second mark (there are three marks in total) on the cylinder. Keep enough slack on both servo cables (about 2-3mm) and you're done! Cheers!
