Changed Final Drive Gearing 2013

[CIP57_imp]

In physics, to cover your butt and to make sure other folks can do the same experiment to see if they get similar results you need a measure coarse, accurate clocks/timers, a means of accurately weighing the bike and a record of atmospherics. All variables have to be taken into account and the more runs you can do so you can average the results the better.

Unfortunately, and I don't want to sound mean here, but those videos are no better than hearsay. No attempt to show a measured distance nor any timing device. They neither support nor dispute your claim or Bob's.

Now it you two could meet at a drag strip, make several passes, swap sprockets and repeat more runs, then we'd have some real data. Plus the opportunity to sling mud in person. In good jest of course.

Robe, i have been documenting runs since the bike was stock to see what gains are made with certain mods. It gives me a real good idea of whats happening. I'm not challenging anyone my post was just for information which i think i presented in an honest fashion.

I'm just a normal self employed guy, my son is a mechanical engineer and teaches night school. He read through these post with a grin. He said he may give this project to his senior class next year, his comments where there are to many factors to consider to make a decision based on physics alone.
