Thanks cxman hows the sound also?cxman said:i have a single on one of my cb750dohc when it warms up a bit i will go see if i can get the side covers off to take a pic

Thats cool didnt know it was growing in popularity. So loke a 4to2 carb setup I assume its stronger on the low end?cxman said:well since the experts have spoken i dont need to go take pics lol
how ever not to worry info on new single carb kits will be seen in abundance buy several manufacturers this year
that are centered in new manifold ideas and rotate around mikunis new hsr pumper 4 stroke specific carbs
i run a hsr42 on my 750
xb33bsa said:trying to put a single carb on a 4 cylinder machine is a fool's game dude, there is nothing wrong with the stock carbs if you can't tune the bike with stock carbs, which is actually very easy to do, what makes you think you could with 1 ?
1 carb will never work RIGHT on the 550 4 the motor..it is cammed totally wrong for a single carb,you would need a cam that basically cuts the horsepower by 2/3rds or more , moving the peak down to 3600 rpm's like an industrial power unit
mydlyfkryzis said:They are also looking at removing 3 cylinders to simplify everything. Oh, never mind, Suzuki already did that....One Carb, One cylinder, One sparkplug.... Much easier.....

jamesbekman said:If you ask me the way to go would be doing an upgraded alternator to provide the proper voltage at idle to run FI. Then you can decide if throttle body injection or direct injection is what you want.
Sonreir said:Yup. The Holy Grail modification for vintage bikes.
if a single carb was better for more hp then you would have seen it used in racingAlphaDogChoppers said:The thing about a single carburetor vs 4 carburetors is that with the 4 carbs, the span of time between intake pulses brings flow through the carb to a halt between pulses until you get to fairly high RPM. With a single carb, there is pretty much a continuous stream of intake pulses at a much lower RPM. Powerband comes on MUCH sooner. The fuel/air charge coming into the manifold through the carb has momentum, and when the next intake valve opens, the charge is already there, and may even have a little bit of positive pressure to blast into the combustion chamber just as the piston is starting to draw in more charge. At the end of the intake stroke, that cylinder has set the charge in motion for the next cylinder. Each cylinder enhances the flow for the next cylinder after it.
Much like the exhaust pressure pulses in a 4-into-1 exhaust makes each cylinder benefit from the scavenging energy of the other cylinders, a 1-into-4 intake could do a remarkable job of ramming more fuel/air into the cylinders if designed properly.
I am really looking forward to what Murray come up with.

the cam is designed for individual tuned length intake and the harmonics gained from that, it is all lost with a single manifold so no you aren't solving any problems just creating themTune-A-Fish said:4 Into 1 intake with a Harley FI throttle body, ecu and rheostat type throttle. problem solved.
Now just need Sparky to figure out how to wire and power the thing, where to put corrected ox and crank (epoxy magnet to stator?) sensors and dial in the gui and software flash.
