Broken Clock

[Major Softie]

While on the heating aspect - what's the drill for using a Twinmax or other carb balancer? Put a box fan in front or do you do it while riding?

At idle you're fine. At fast idle, yes, a box fan - or better yet, one pointed at each cylinder. OTOH, I've only used a Twinmax on an Oilhead, and I find the greatest advantage of that tool is the ability to check balance under load (while riding). Airheads aren't as sensitive to intake balance as the R1100, so few bother with such things on these. I did my /2 by ear.
