Here's another bike I did recently....another bike with a muffler change that would
barely run. Ever see a vacuum operated, constant velocity, twin carb set-up on a
V-twin engine ?....probably not. This one had a $85.00 "jet kit installed with the pipes.

I had to remove the jet kit and re-do it myself....I nailed it on the first try.

Like I said....I'm a "carb Guy".

FBD.
