Thanks to all for the input. It seems that while the EGT gauge is not the
end all, it can be used as a protection against too lean conditions and this
was my main concern. With the progressive nature of the Weber, it tends to
lean out at high rpms and the gauge should show it. I do not want to pull
the motor to go to a dyno. Thanks again.

I have used EGT on a dual Weber equipped Honda S-800 and have found it
helpful. If you have two Webers, you will need at least two sensors to
evaluate the performance of a cylinder from both carbs. In general, the idea
seems to be to go for the highest temps and then back off one jet size to
avoid a mixture too lean. On my engine, the temps I tried to get were
1200-1300 degrees. If you have access to a dyno, it may be worth the time
and money to find your optimum range before going to the track.
