That guy is most certainly an expert but following his stuff does not guarantee perfect running if not all of it is done at the SAME TIME. These carbs throw most people for loops who until they ran into them thought they were pretty good at carbs, these show you otherwise.
They however can be made to run for long periods of time with zero issues but the first thing you must have is a 100% rock solid engine as the carbs will not run at 100% without that. CV carbs rely on the engine draw to open fully, and these are the worst as they are solid slide operated, they do not respond as quick as normal CV slides with rubber diaphragms.
Nobody ever sets the valves because they require shims and then the engines just slack off in performance when the valves begin to burn and most people then blame the carbs, which can be an issue but lots of times are not. Bike then sits and THEN the carbs become a major issue.
The primary jet circuit is positively linked to the idle or pilot circuit on these and the primary relies on the idle circuit to lean out a certain extent to make the primary jetting correct, when the idle fuel feed clogs the IDLE leans out but as soon as you transition from idle to PRIMARY flow the flow goes RICH as the plugged up idle restriction kills the idle leaning out the primary, what I mean about one circuit seesawing the other, they both work at the others expense. The engine typically is super lean at idle then goes super rich just above idle, why everybody goes nuts trying to figure out what the h-ll is going on.
