Keihin PWK 28 Quad Vent
Posted: Fri Feb 26, 2010 3:08 pm
I just bought a second hand PWK 28 that appears to be a quad vent.


The needle shroud ,don't know if that's the right term, is cast and has a cutaway at the front.
What is the point of this style of shroud?
As a bonus these come with a chrome slide


I read somewhere that the quad vents might help with bogging on low throttle.
Can anyone shed some more light on this?
