I was very tired of the carb problems with the 750!
About a month ago I converted to a single 38mm Mikuni CV carb.
I made a manifold out of stainless tubing. Because of the angle of the head spicots, it took a while but was more than worth the effort.
The carb comes out the right side of the bike.
The bike now finally starts in seconds......no flat spots......no more decel pops...... and looks COOL!!
I can now remove or replace the carb in minutes for inspection or cleaning (which I had to do because of bad gas recently).
I used a 38mm only cause that is what I had but I know that a 36mm or even a 34mm would work as well.
Plenty of power and very smooth though-out the RPM range.
Have not checked the MPG yet and I really don't care about mileage!
I hope to sen some pictures soon.:)

Can't get through on that site anymore.
I think your freind Wolfe has blocked me from the site.
I have a freind coming over today to show me how to post a pic for you guys.
I'm still frozen in the time of tankshift-foot clutch motorcycles and $2 beers!
Hope they come out ok cause this mod is the best thing that ever happened to this bike!
I can now ride the thing knowing that it will start up again to get me home!
Even if something is needed on the road it's one screw and the carb comes off!

I'm not really happy the way the pictures came out.
They make the carb look much bigger than it really is in person!

It looks pretty much the same as a Harley set-up.
Oh well, at least you have some idea of what can be done.

Any way you could post a video of it running? I've had this idea for awhile, and right now I have the engine out to replace the stator and balancer dampers, so I was able to get some good measurements. I'm working up a design for a manifold on AutoCad, but I don't see any way to actually build it. I would most likely have to change the design. I like things simple, and there is nothing simple about the 750. But jeez whiz, it takes longer to get the carbs off than it does to pull the engine. Jerry.

Update:
The carb set-up works perfect!
It starts perfect everytime and is smooth as glass.
I don't notice any difference in power or gas mileage.
I did not even have to change the jets at all!!
I am using a 38mm but I think that a 36mm will work as well.
If you are having any problems with your carbs, I strongly suggest doing this mod.

The only change I did was to heat up and bend the rear brake pedal out so my leg does not hit the air cleaner.:)
