Re: what did you do to your motor bike today? Lol Happy! I wasn't raptured either, so I guess we're all sinners, of the 2/4-stroke... Cowboy, these engines don't like not having any back-pressure, they tend to over-rev and disintegrate stuff... like bearings. My father always told me, "An engine will always run better just before it dies" take heed, brother.
