I THINK THAT I can only go to 1 1/4 because I have to come up tires the triple backbone. So I might go at it again or I can just leave it alone. I am sitting on the bike where the passenger would sit and the front fork tubes are 4 inches up threw the triple tree. So the handle ling had to take...

This is the finished process, I had made carburetor changes many times, I went from a ford escort weber to a ford 2 bbl to a 140 cid 6 cyl holley 1904 1bbl, and now finally a 1920 holley 1 bbl from a 223cid jeep from 1965. The 1904 holley worked good but the venturi was smaller than an inch and...

Got it on the road, had to replace the 2100 autolite carb with a holley 1904. I have the plenum heated and when the bike was up to temperature the 2100 could not be dialed in. The 1904 is off a industrial 144 cubic inch Ford 6 cylinder. The venturi is realy small but if works good. A bit of...

The autolite 2100 or motorcraft 2100 and 2150 were used on ford v8s from 221 cubic inch to the 390 and 400. It was made from 1957 to early 80s They had the venturi written on the side of the carburetor .98 1.01 1.02 1.08 1.12 1,21. The one I,m using is a .98 venturi 190cfm from a 1962 221...

Well I am on stage 3. I,m a big guy and didn't fit, So the vw plenum had to go, I made a 5 inch by 5 inch by 1.5 inch plenum with the runners coming up from the bottom. What I did different is that I linked 1 and 4 together and 2 and 3. I put a divider in the plenum and had to turn the autolite...

It runs, had a hard time dealing with vacuum leaks. the rubber boots are old and hard, anyway Got them sealed up. The idle is very good and responds to throttle very quickly. Starting is almost instant when shut off warm. Have a bit of fuel puddling in the rear of the vw manifold, as I,m only...

I have a hard time leaving things alone

Here are some pictures of my slow progress, the hose I used is pretty close to what gas pumps use, To get it to bend I had to bring it in the house and soak it in hot water to get it to bend a bit.I have to get it moved forward about an inch so I have a lot of trimming and maneuvering so I have...

Still at it with the second revision,I,m now using a two into one approach, pairing one and two and coming up threw the triple backbone, same with 3 and 4 on the right side much neater. I have to make two block offs for the other two outlets on the vw plenum, was using copper pipe with silver...

ok will do that, thanks

Ok how do I disable it, I was watching andrews wennstorms video, about taking out the spring, maybe thats all my problems

Here are a few pics of the setup I used an electric fuel pump that is good tp 5.5lbs I ordered a 45 and 50 idle jet and a 90 and 95 main. I used the carb holders that attach the 4 carbs to head, now with the holders off the 1 and 2 are angled in to the center 30 degree with a slight upward tilt...

Redline is 9500rpm so its probably low vacuum at 1300. and after the power valve spring was disconected it was better.so I guess the power valve was open at idle or closs to idle. I guess I need a smaller idle jet. I did notice a difference going from 105 to 100 on the main. I have a motorcraft...

I,m sorry to post this, on a goldwing forum but I don't know where to get information, I used this forum to help me with this mod, not much info on this type of modification on a inline four, but the firing order and piston pairs up and down seem the same. Anyway I used the vw manifold and had...
