Benefits of adjustable timing plate

My high school shop teacher explained it like this. If your buddy is across the street walking down the sidewalk and you want to hit him with a baseball, you have to throw the ball in front of him to hit him. Now if he's running down the sidewalk, you have to throw it farther in front of him to hit him. Same principal applies to ignition timing. Light the fuel before the piston gets to the top so that by the time it starts really making pressure, the piston is just past top dead center. That's why you have an advance curve with more advance at higher RPMs.

 

Yamaha set up the timing and compression very conservative so that any shit gas anywhere in the world could be dumped in it and they wouldn't be replacing a motor under warranty.
