I have looked into the O2 sensor thing; on the web, and have found wide band kits [they call them fuel/air ratio guages] that range in price from $190 to $350, plus shipping. some have provisions for data logging and narrow O2 sensors for indevidual cylinder monitoring etc.
What is the advantage of a narrow band sensor over a wide band sensor?
What does a narrow band kit cost?

I looked at the link for cv carbs, however I have never had a need to adjust any cv carb I have owned. I have adjusted the carb on a XR100 that I used to mini road race. In that case it was because of modifications to the engine that provided more air flow through the engine which resulted in White spark plug electrode, Indicating leaness! i changed the main jet two sizes bigger and the plug came back to a nice light tan colour and we did quit well in the 3hr endurance race without any damage to the motor.
