Hmm OK. I thought the newer M4 would be pretty light where all parts
are titanium (except for the carbon fiber parts if you get that
option). It would be cool to get exact weights. I assume baseline
jettings would be about the same though?

Hell yeah, I'll take them! But for some reason I thought you just ran
stock gearing.

Well I am going one step at a time. :) But thanks for that advice. My
main goal is to see how light I can make the bike, but if I still have
money I'll go for power too.

I figure for now I can just change the pipe and jetting and still run
superstock until I change the subframe. Obviously right now I just
need more track time than anything else.

You coming to Barber this weekend?
