I have a 92 3VD as well. Are you running stock pipes? I have #142.5 mains installed and have no issues on the top end, but do run an aftermarket pipe.

You could reuse your old #140's after a quick cleaning. It's really just the needle and emulsion tubes that wear out.
Â
Top end issues = Main jet
Midrange         = Needle clip position
Low end          = Float height
Â
Factory pro is expensive, but I don't regret spending the cash on it. Getting 48mpg-52mpg pending on the day and how I ride.
