What's the difference between CA & Non-CA carbs?

[dannymax]

I really don't see any difference except the brass spigot (similar to a sync spigot) that comes out of the throat of #2 carb and goes, I believe, to some sort of canister.

I think there is a difference in main jet sizes on CA Ventures, but I'm not sure if this is true with the V Max.

Are there any internal differences? Can the CA carbs be used on a Non-CA engine by simply removing the rubber hose and plugging that spigot on #2?

Yep, that's the only difference. I've seen some US49 bikes with that little spigot on it too.

Thanks Mark-o. Doesn't look like any issues (except maybe minor jet changes) in using CA carbs on a 49 stater then....great!

Thanks Dave, I knew about the needles and Pilot jets but didn't know PAJ1 was different.

I have Cal carbs on my non Cal, Pinnwall motor.Had to take off that (fuel vapor return canister)and hose.Left the vent open on the left front carb.set the pilot screws at 2 1/2 turns out.Never had a problem:biglaugh:

No kidding Rusty!....I thought it would pull vacum through the brass spigot. That's good to know, I won't even need a cap!

Thanks! :worthy:
