Anyone run a single carb?

I don't get it. What's the reference to? That they are all equal length? Or that he should buy one of those cast iron manifolds for his bike?

O man, ur a piece of work. Those designs are what i wanted to make originally, just in appropriate lengths for my bike.

"Yea, I was thinking that Ford manifold would bolt right up...."

You should do it before Billy Lane steals your idea.


Your reference to inlet location doene't really mean anything. If you have a plenum, it doesen't matter where the inlet is (to a point). That's why you use a plenum. There is a charged mixture in the plenum waiting to be pulsed in to the next available tract. As you increase plenum size, you lose throttle response. The rule of thumb is twice the engine volume (not the gospel).

I you want them, I can give you the formulae for this application.

you may want to consider something like this. Note the lengths....

This appears to be a very well designed single carb setup.
You said in your first post that "ease of tuning" was the main reason for fitting up a sigle carb.
Those cast manifolds that have been shown will work ok. However, you must expect to loose some performance from your existing 4 carb setup.
Those cast manifolds are manufactured that way to keep the costs down for the manufacturer. They are a no nonsense, average performance solution which Jo Public generally accepts.
Whenever you introduce right angle kinks into a gas flow, you create resistance to flow (drag). This is why most serious race engines have the inlet tracks aligned as close as possible to the valve pocket/seat areas. This is also true of the manifold tracks.
If ease of tuning is your only concern, go for it.

Are you always this sensitive when someone isn't clear about what it is you're tlaking about or possibly even disagrees? It may be time to stop taking yourself so seriously.

LMFAO!!!

I thought it was already covered. You know, like a parrot, repeats what you say.... LOL
