Oh No, I did it again! Final(?) update post #43

Looking at data, Carter YF was rated, depending on version, from 170 to 220 CFM. That should be enough to give you back some or all of the punch you lost with the little Holley.

Looking forward to hearing how it comes together!
 
I finished the heat shields yesterday and will install them today. I'm pretty sure they will stay in place without any issues. If not, I'll have to re-engineer them.

This is it with the little Holley 1940 mounted in place. As you can see, it is a bit tight in there, but I am 84.369% sure the Carter will fit.

New carb has arrived, been modified and installed. This is what I wanted when I bought this thing. While the single carb may not deliver the same HP as the multi carb stock arrangement, it pulls pretty hard with smooth and liner power. I think the stock carbs that have been fighting me have something wrong with them that I am no longer interested in trying to sort out.

The new Carter YF clone:

The difference in throat size between the old Holley 1940 and the Carter YF. By my calculations, it is 38% larger in area:

Everything on this side has to go away or be modified to fit the application:

I took a moment and painted the top of the motor while I had the carb(s) off:

I cut off the hot air choke and repurposed the choke arm from an old set of Goldwing carbs. I had to make a bushing to reduce it to fit the carter choke shaft. I also used the throttle quadrant and cable holder from my parts carb set.

It tucks up under there nicely.

I realize this is moot now, but I'm curious... did the manifold as supplied have a large enough bore to incorporate the Carter or did you have to open it up?

Based on the photos of the manifold and the Carter base gasket, it looks like it is large enough, but just wondered?

At the end of the day, I love what you've done with this bike!
 
One last post on this thread:

I have put about 150 miles on it over the last few days, still working on a few bugs, but basically, it is done. I have had a fairly steep learning curve on this bike and I don't think that I have ever had a more stubborn resurrection. I have had to do several things two or three times (in, in the case of the original carbs, I had them out five times. Heck I even had to replace the gas tank due to a leak that didn't show up until I had put a few miles on it.

But the good is that this is a very nice bike to ride. For my 6' frame and 32 inch inseam, it is a nice roomy ride. It is rather heavy, about 650(ish) pounds. Even though it is a chunky beast, it's a nice pleasant ride as long as you remember that it has 50 year old brake technology and you need to ride it accordingly. I am going to keep upgrading it as time goes by. I have another project about to launch, so I probably won't do anything to extensive on it until next year.

Finished exhaust. I'm so happy with my choice of mufflers as the sound is much more inspiring than the stockers.

Sorry for the cluttered background.

Well, that's it. If there are any updates to the Goldwing saga, I'll just go ahead and start another thread. It's sunny outside and I think I am going to take a little putt around the neighborhood.
