In any other motor, it's a good way to explore the wonderful world of pre-ignition.
The bike is noticeably faster. better response, better top speed. top speed the before the switch 35, its now 40.(speeds off the speedometer) We made the same change on another bike with similar results.
Rotating the head so the Spark Plug is on the front (nearer to the front tire.) is the only change we made.
I don't know why it works, but it did for me.
