carb vent plug question

[allenmp]

I have a 03 chop and just put a new super g carb on and rewired the bike with a single fire ign. System and it has V & H big radius pipes and a dual runner intake 107" motor
I have seen where with a after market breather you should remove the aux vent plug
my question is in the carb tuning guide its #14 on the exploded view
looking at carb from breather side its on the outside bottom left if I am looking at it correctly a little allen wrench removes it
the reason I want to confirm is because it just seemed odd to just leave an open hole on the outside of my carb so any input is appreciated...
thanks
Mike

yep #14 in the tuning guide, but notice #8, thats the normal bowl vent path that works with the S&S tear drop cleaner. When you start jacking around with other air cleaner set ups they suggest removing #14. I guess they figure another set up may cover up #8

Ok just felt odd to have an open hole on outside of carb thats not filtered or something I dont know if it breaths in or out I took it out when it was running and didnt feel anything but put plug back in incase it was wrong one
thanks again

Not doubting anyone word just confirming
how does it not get dirt/debris in this hole and fubar the carb since its basically just an open hole on 5he outside of the carb I am just trying to grasp it I guess if it allows more air in doesnt it pull dirt also??
Thanks

I am not sure if it "sucks" air... but I know it does compensate for the atmospheric pressure inside the carb.

I´ve had it off for more than a year now and I have not found any crap inside the carb when I checked it out. If S&S recommends taking it out... I guess they know what they are saying?

Someone with more techinical acknoledge answer this one... please?

 

[allenmp]

Not doubting you by any means franco I appreciate the input I just figured I would put a pic to verify I was pulling the correct plug since it was outside a filtered area I have had my share of trouble with the dog and so called techs working on it so I am just trying to grasp what I can on my own
thanks
Mike

All good Mike, yep, that´s the one in your pic.

I am hoping someone can give us a better explanation. I am curious too.

Whoa, listen to you, atmospheric pressure, I can't compete with that, I only have a GED, you go boy. I'm impressed Franco

Ok pulled the vent plug and went up a int. Jet size ran ok but still some hesitation and poppping at low rpm I have to work so I will go through the carb and timing procedure first chance I get with the new carb and ignition setup I might just have to work with it and find the sweet spot
