Bike Carbs & Bogg Bros Manifold

[craig_007 1]

I have the above set up on my MI.

 

I've been out lowering the rad to tonight to try and get some cool air into this and for some reason or other I lifted the slides on the carbs and opened throttle fully.

 

Am I right in saying that the mating of the manifold to the carb should be smooth as if it were one so to speak,On mine where the carb mates the manifold (with silicone pipe & jubilee clips ) There is a difference where it mates,I.E it creates a small ledge where fuel could likely get caught !! (this happens on all 4 carb intakes)

 

Quite hard to describe a picture would likely be better but thought I would ask the question ??

a smooth intake path without steps is always preferable, and will give you the best results. However, if you look at a lot of standard engines, there's normally a fair overlap on a lot of mating joins so it wont cause a big issue, just it's not optimal for performance.
