Robin,
The problem I had with the VM was very similar...sensitivity to
changes. Which leads me to believe they could be an excellent carb
that would achieve the best power if carefully tuned for each
situation. I needed more of a broad spectrum of performance. The
Keihins while possibly down on max power compared to the VM's are
very forgiving and easy to find that 90% point.
When you get the VMs dialed in on the dyno I'd appreciate you
shooting me and email with what you ended up with for settings and
some details on the engine/pipe you are running....good data for the
database.

Race 1: Day 1: DNS due to a "funny noise" that ended up being a piece
of valve spring I broke last year that found a bad place to hide.
Race 1: Day 2: Rain...crashed twice....in the same race.

Race 2: 200gp...1st place. ULWSV 2nd...finished behind one of MY
BIKES that I loaned to a club hotshoe who then proceeded to beat me
with it :) Learned a ton from following him around the track though.

way lean! The more I richen it up the better the plugs look and the
worse the bike runs. I will through it on the dyno with a speed tune
and figure it out. It was running so good with the other pipe. I
know I can get it back there. I think it will be faster with this new
pipe.
