Maybe this already exists but I was thinking it would be awesome to start a running list and then maybe move it to the technical section of how people's carbs and exhaust and all that are set up. I can't do it properly because I can't remember my jet size (doh!) but I think this might help a lot of people get a good starting point for themselves.

Answer these questions.

Is your bike well tuned?

(thanks guys we're building a good list!)
Any thing else relevant?

Okay, I'll jump in

Air Filter: K&N stock replacement
Petcock: stock
Main Jet: 152.5
Pilot Jet: 52.5 with bleed holes
White Spacer Mod: filed down to 2/3
# Turns on air/fuel mixture screw: approximately 1 3/4
Exhaust: free-flowing (baffle-less) Dyna

I like the way it's running right now.
