Interesting...

I contacted them earlier about how this setup performed, this is his reply.

Dear mralex714,

"Hi there, best thing you get is gas mileage and easy, really easy maintance, and inexpensive parts. Bike will perform as good as with the 4 carbs and you will get same top speed. But you gonna loose the torkiness and fast response in the lower speed taht the 4 carbs give you. Please let me know if you have more questions.

Hi Michel,

Soon for a ride.

Salut Michel,

A bientôt pour une balade

Chris

You know, get this manifold, get a TBI (carb based fuel injection system) off a similarly size car engine, and volia! you got FI! Ok, might have to increase fuel pressure, but my Astro has a TBI and it is running between 9 and 13 PSI, so not by much.

It' s just what I want to know.......... thanks

On the net I have found video of gold wing with the " kit ", but nothing for venture............ if someone have pictures or vidéo it' s will be nice to see that on a venture

Mich.

I wonder how much gain in mpg and also, aside from occasionally syncing, is the four carb set up a problem, reliablility etc?......

I wonder if the setup would even fit under the gas tank,...?

I asked about that also and his reply was.

"Dear mralex714,

Hi there, this is 8 by 6 by 11 tall! I will be posting few pictures of the King in the bike in 2 days. Theres no need to keep the air box cause its remplaces by the filter provided. And it all fits under the fake tank!!!

With all those welds to make up the manifold, I wonder how clean the airflow is?

If it is rough inside, some of that low end might come back by cleaning it up some.

According to typical engine design, Torque should go up with a longer intake runner. Anywho you can send me those gummed up, tired, unsynced, leaky carbs and I will pay postage.

According to typical engine design, Torque should go up with a longer intake.

Low rpm torque should go up, but in the 2,200-3,500 rpm range. Off-idle response (900-1,800 rpm) will go down from the 4-carb setup due to low air velocity in each of the intake runners not fully charging each cylinder with fresh fuel/air.

I like the idea, but think I'd want to know someone else's experience first for torque and mpg. For that trouble and expense though, I'd hope to be going a long way towards full fuel injection.

the simple reason the ONE carb set up is not have the torquey feeling and the seller said. It is a car carb the has fixed jets and the ONLY moving part is the butterfly for throttle...which always results in some lag. Similar to the performance of carbed bikes in the 70's before the CV design. UNLESS there is an accelorator pump on it...which I DO NOT SEE. But accel pumps really cannot fix the lag totally.

Did anyone ever try one of these single carb. units?--

Does anyone have a phone number to the supplier?==

The unit says thru 1988- I have a 1989 = Wonder if it would fit?

Thanks, Hushpuppy

There is no physical difference in the block up through the air box in an 83-93 V4.

Venture 83-85 carbs are smaller venturi's, but same mounting dimensions.

If it fits an 87 it will fit rest the of them.

Saw one of these at Ashville few years ago. Didn't get to talk to him enough but it sure looked interesting. I'm thinking it was a 2 barrel?? A small 4 would be the way to go??

I've been thinking......PVC Intake?? More ABS plastic???? 650 Duel Pumper??Thinking gonna get me in trouble again!!!

Unless you add a blower I don't think you could get enough air thru a 650 to make it work.

but then maybe a 390 double pumper.......... and a blower........ sounds like trouble to me.

OR if you are going to do all of that work. use a throttle body fuel injection.

How does that European Money covert to dollars ???

ie: how much does it cost in dollars???

Thanks for the info.= Hushpuppy

I know it may sound neat to have a single carb but we really need to ask is what is the benefits of the switch, risk Vs reward scenario.

Unless we can use a FI unit, I doubt if it has a great benefit.

My worth.

Seems like you guys wanna duplicate whats already been done to the Corvair back in the day.....

A 4 bbl in place of the 4 carbs.....

Cain't find the daggone pic....
