I have a GTech Pro meter which I use to play with when I had my REX. My current Subbie is not worthy using this instrument . Its a tool you can use to measure certain performance data. Below is a pic of the data it can collect. [img:640:429:404658fcb0]http://img291.imageshack.us/img291/817/4waycomparo30aug03lc5.jpg[/img:404658fcb0] Has anyone tried it on their bike ? I think I found myself a weekend project ! To wire up the GTech to my VTR and do some performance runs. Hmmmm, makes some interesting coffee night comparisons. If I figure out how to tap into my bikes electrical system to get an RPM output - i'll post up the data. And if someone can let me borrow an R1, lets see if they can do 0-100 in 3s !
