Enrichment v choke

[Tom R]

Since the cv carbs have an enrichment system instead of an actual choke, regardless of what the cable says, what effect would it have to keep it open a bit around 1/4 throttle and up? Obviously with a choke it would run richer throughout; but from what I could tell, the enrichment system gets all it's fuel from the pilot circuit. Would it prevent the slide from opening fully?

Personally, I prefer to let the carbs function as designed, so I can fiddle with other things. Sure, you can let it run rich, but it might foul plugs when it warmed up. The vacuum operated slide will be able to open as much as it wants, but the rich condition will interfere will its response.

Hi,

Once you actuate the throttle it defeats the enrichment circuit, the "choke" no longer has any effect.


Thank you for your indulgence,

I'm relatively new to this bike and this type of carb but when I bought my bike last year the carbs were very messed up. When riding at highway speeds (topping out at 65ish mph) I found that adding a little choke would give me just a few miles per hour faster. That being said understand the carbs were very badly setup, one of the mixture screws was broken off in the carb, and if I stayed at speed I would loose vacuum to operate the fuel petcock.
So for me opening the choke helped but it may have just been the way the carbs happened to be working.
