this is a down and dirty (sorry no tripod this time) of how to do a valve adjust on a genesis 16v yamaha. found in yzf600-yzf600s fzrs. similar to many other bikes. but this will be identical to all 95-07 yzf600 USA bikes. I start the video with the tank, plastics, airbox and carbs off. see other tutorials at yzf600r dot com forums for that and more info. you might want to check out my other videos relating to valves that might show more detail. this is done motor in frame as per manual
