Was curious as to what jets came in my 07 Vector Mtn. Got the carbs off and apart and found the mains. I am sure the number on the main jet, 142 is the size. Seems to be about right for what I am riding at, 7-10000 and usually between 10-30 degrees.

Why do only 2 of thhe 3 carbs have a vacuum hose attached and the third capped off. Also since I broke into the cooling system with the heated carbs would it be a good idea too bleed the system even if I ride with the carb heat off?
 
Another thing, where can I find some information on these carbs? Can't seem to find any information on the Keihin website.

2 vacuum signal to drive the fuel pumps.
Only 2 pumps, thus mag carb tap is capped.
