Topic: Airbleed needle K6 750

[Markcb750]

I am trying to make sure the low speed circuit of my carbs are correct, have a black plug issue on my STD D8EA plugs driven by stock coils and a Dyna point replacement unit.


The low speed adjustment needles are very ineffective and I wonder if the hole just above the taper of needle is standard?


Just seems counter productive, none of the rebuild kits I have viewed on the net show this clearly enough for me to know if they are different.


thanks

I couldn't tell ya but I will be watching cause I have a 750 k6 also.... My plugs turn black eventually. Probably self induced though gettin on it too much....On top of being a little rich.

The hole is OEM.  TT will explain all about the boundry layer flow and inertia of the gasses.

Thanks King, this is what I needed to know, the physics of gas(mass) inertia is "less" important in these situations then what the engineers at Honda iintended, experience trumps theory!
