C'mon... I didn't mean to ridicule you... just having a little fun at your expense.. :) You're not the first cowboy showing up here with a quarter horse looking to turn it into a jackass. Nor will you be the last...

If you want do it... read up on the link I posted for you for a starter and if you want the pertinent air / fuel requirements I'll do that for you... seriously I will :cheer:

What the hell... succeed with it and the hand out salt shakers with the crow drum sticks you'll be giving out... we'll have to eat them :laugh:

Yes..but because you can't synch something to another if it doesn't exist...

With a single carb setup and plenum manifold you can run into uneven fuel distribution between cylinders because of the uneven pressure differentials per port. That stated you really can't claim the single carb as beneficial from that perspective.

With one unit per intake runner you help to alleviate that situation.

If carb synch difficulties is your main issue then consider this. The last years of the bike Kaws with carbs on them used CVK Keihins. The're a breeze to synch because the use a simple phillips head screw that's spring loaded...no locknut to fuss with.

A member named Bozo... put a rack on a KZ1000 and according to him, they worked great. That might be and alternative project but with more promising end results and less modifications. You will most probably have to re rack the carbs though.... But as I recall the first 600 Ninjas had cam chains down the middle of the engine so perhaps ...might be a possible fit with less work than a motor with a cam chain on the end of the crank....

Look him up and send him a PM. He built a nice bike... He's NOT a hacker by any means...

Same with cars. High performance cars that used carbs nearly always had multiple carbs. In fact, I can't recall any top of the line performance cars that used a single carb. Ed

Just one example:

Did you use top of the line performance cars and a picture of a Pontiac with 3 deuces in the same post? :S :woohoo:
Ls-6 454 in the 70 chevelle/L-88 427s were mostly single 4 barrel motors from gm,the original Lt-1 370hp 350s were single 4 motors,thats just a couple off the top of my head anyway
Motorcycle motors and car motors are 2 totally different animals as far as design and lay out.


Using three deuces had the advantage of allowing running off just one carb for "normal" and then the other two kicked in as you get on it. Even the gigantic 1050 CFM Holley "double pumpers" which were supposedly one four barrel carburetor actually were two carburetors. The smaller primary side for normal running and the giant secondary when you wanted to spray raw gas out the tailpipe like a crop duster....

Ps I know I am bucking the trend. Some years ago I saw a tubo-ed kz1000 and it had only one carb, I am not going to put a tubo I just like being different


No, you're not bucking a trend....you're bucking common sense and logic... IT IS just that simple. But it's your circus so you can make the animals dance anyway you please.... The mistake is in thinking the crowd will applaud when you turn a roaring lion into an armpit scratching monkey... :)

If you want to know how much air flow the carburetor needs to meet the piston demand..I'll be happy to give you that number. But remember this... A carburetor's primary job is to deliver the appropriate fuel curve for the entire RPM range of the engine. That's the part that's going to take some experimentation. I suggest you start with an old dirt bike carb fitted with a power jet, a slection of needles and a box of jets. If you want to know how many lbs of fuel per hour you need the carb to deliver, I'll give you that number as well... Then go have fun and holler back with the results... :)

Here's some reading material you may find useful in your endeavor.

Bear in mind, that back in the old days, most car engines were severely under carbureted so you could bolt on more carb and get more power. Bike engines are set up pretty much on the optimum point for the cams and headers so that doesn't apply.

Mopar used 3 duces back in the day....they ran too. In 70 they had AAR Cuda 340 6 Packs. They build just enough to meet homologation of the Cuda and I think the Dodge Challangers for the T/A racing class.
