Dual Carbs?

[Harp]

Hello I have been thinking about this for awhile but never had the
time to do this idea. I'm not sure if there is a thread already about this
but I was wondering if it would work out
if I put on
"Dual Carbs on the bike".
If I somehow spit the inlet and have two stock carbs attached.
And split the Throttle cable and have that split aswell.

I'm thinking I would increase my revs/touque due to the increase of
gas and air intake but not sure how everything else
would turn out.
Is it worth going with this idea and testing it out?
Or would it just be a No go type of project

Harp,

Howard at peddling motors flipped the jug 180 degrees and mounted 2 carbs on a siamese manifold out front.

He has a video of it running...I'll see if I can find the link.

Harp,

Here it is, it's cool.

I only see one throttle cable and one fuel line to one carb...am I missing something?

Yeah, You're right...I never looked at it that good. I'll have to call Howard and ask him if it worked.

The video was to show-off the engine test stand, so I don't know if they were just running on one carb to try out the stand or if they have ever run it on both carbs.

Knowing Howard he has probably ran it on both carbs...how well it worked...who knows.

I am wondering myself how well that would work...cool set up thats for sure.

Cool, perhaps but why? Our carbs run pretty rich anyway with stock jetting and idle mixture.

Along the same line as doubling up, I wondered if there would be any advantage in modifying the head to take 2 spark plugs. Some bikes, like BMW, have dual spark plugs.

I thought it might, for example better ensure complete fuel burn.

Say, I know just the guy who could machine such a cylinder head . . . (Jim?)

I know most of you folks are mad scientists of the highest order but I have to ask again, Why? We've got single cylinder 2-cycle engines here most of which are made with questionable QA standards. For what you spend modifying these engines so you can blow them up you could buy a motorcycle with more power than you'll ever get out of these things. Yeah I know I'm being a wet blanket but I just don't see the point. I'm all for accessories that make them safer or easier to mount and use but going for excessive power seems kind of pointless to me.

Not so much a wet blanket. Jus' helping us keep things in perspective, Fin.
