Got any charts? Where did you get it?!?!?!

I think you should take it off and sell it to me !

I should probably do this in the "test" area, oh well - here goes

Well, it's not pretty but you can kinda sorta read it. If you can make heads & tails of those numbers, then this set/chart will get you a top speed of 201mph with your tranny gearing + 29 tooth rear sprocket and a 15 tooth front.

A 17/33 should get you 201 also. Sorry about the first one. And in case you couldn't read the post above this one the top MPH for the 17/38 was 174.
