Haynes makes a pretty good manual on SUs. Just don't admit to anybody that you bought one
Now, if you could come up with a trio of Weber DCOEs....

I measured my throttle bores and they are only 1.37. So yes, kinda small, but maybe good for cruising down the street in the 4th of July parade at 3 mph. A YF 1V has a 1.65 bore, but these SUs dont have a small venturi. I'm thinking they have about 40% bigger throttle area.

I built this intake last week for them. It usually takes me about two hundred hours to fabricate an intake manifold using hammerform dies. This time I decided to make it out of flat aluminum stock. It only took about 40 hours to get this far. I still have to make throttle linkage and an equilizer tube, plus polish it all up, but you get the general idea. Does it look old fashioned? I did zero calculations on it - just grabbed a pencil and sketched the runners kinda seat-of-the-pants like.
The carbs shown in the photos are HS3s that I had acquired earlier, along with the bolt up balance tube assembly. They were used for mock-up but it is now my intention to use the HS6s. Or try both sets at some point.addo":34zabz1w said:What are the tag codes, or what're they off?
