Adding plenum volume attempts to compensate for unequal runner tract lengths by slowing the charge down. Raising the carburetors throttle blade from the plenum floor, in conjunction with a now slower charge from the added volume, allows more time for the atomized fuel to make the turn to the runner after exiting the venturi and through the throttle blade. Speed of the charge is unaffected since runner length hasn't canged and internal volume of runners is unchanged. The charge is first condensed a bit ay the base of the adapter and the distance is altered some to allow the fuel charge to arrive at the valves at a more opportune time.
It is my view that he sees results with his conversion, yes. But he does not know why he is seeing them and must formulate some reasoning before conveying it. Your reasoning won't hold water.

...nor do I have the issue. Of course not westgl is so nusy revising he hasn't refined a version yet.
Quality construction practices are important.
I equalize distribution by port tuning my individual fuel tracts.
Equalized distribution via increased plenum volume and "centering" the input charge into a intake manifolds plenum chamber is smoke and mirrors as the actual problem still exists. He will find this out once he actually gets time on the bike in.
You will if you ever ride yours.

I suppose they will speak on it for themselves. I don't see them contributing to this thread.
Hott's manifold needed something to mount a two-barrel carburetor to what is normally considerd a single-barrel manifold. I suppose he found it in the adaptor.
Joe doesn't have a stock engine and admits to knowing very little of one as it relates to this particular conversion. Whatever he is doing to his bike pertains to Joes interpretation of his results just as Dans pertains to his. Others may see my view differently.
Finally some truth!

Oh, just a new thread boasting of Tom's carburetor over there. It's good to see people having a easier time in getting a conversion completed in short order, even of ot takes two Forums to make it happen.
I'm happy that others are finally seeing the benefits in heating their conversion manifold.
We've a decent NEW carburetor for a conversion now and most are seeimg the benefits of heating their manifolds as a regular process of converting. :headscratch:
Many have contributed.
