Side drafts

I can tell you as a motorcyclist, the headache of a 4 cylinder carbed motorcycle is irritating. Add syncing carbs with a rack of 4 vacuum guages to your list of maintenance.

Jetting was always a constant once sorted, but on a slant six, 6 carbs, with six mains, 6 floats, 6 pilot jets and 6 pilot screws to tune, then make sure they dont crud up.....6 vacuum guages

I wouldnt go back from my newer efi bikes...
