It is disappointing that the scooter dealers who sell these Keihin copy carbs do not give clear and precise instructions that this feed must not be left as it is, otherwise your carb will suck in air through it.

The disappointing part is that its a genuine Keihin carb and It comes with zero instructions, I have had Koso PWK copy carbs that came with instructions.
I found this guide on fitting a Keihin to a trials bike useful http://www.splatshop.co.uk/how-to-modif ... -bike.html
