Really good to see someone with a nice, original bike do a conversion on it.
I hope your ride goes well. You should find the conversion acceptable I would think.
Again, very nice bike and Welcome!

Just an update: After struggling with low end torque and cold weather idle (no, I didn't solution the heated plenum requirement or choke that must me removed for the single carb to fit inside the frame) I finally lashed out and send the original carbs (which came in a box with the bike) to Pistol Pete for a complete rebuild. Took me about 5 hours to undo the damage (who ever the mechanic was) created by Frankensteining the single carb in there and install the originals. End result? No comparison, the originals are vastly superior. I now have greatly increased torque throughout the RPM range but which is especially noticeable at lower RPM, use of the choke and a smoother running engine. I really wanted to get the single carb to work, but honestly, the original is just better.

I was considering a single carb conversion too but Randakk thinks not a good idea and I asked Stu Oltman for his opinion which was the same as Randal's. So I stuck with the originals. Still not right but getting there.

I actually tried two different solution: I bought the bike with a Webber progressive 32/36 carb already fitted, which ran rough. I rebuilt that carb, which improved performance, but still not right. I then bought a progressive 32/32 Webber, which was a match for the 1000cc engine, but again, was weak at lower RPM and didn't like the cold. Pistol Pete uses the Randakk rebuild kit and it seems to have done the trick. Kind of wish I had bit the bullet originally and gone this way, rather than a year's messing around.

To Paultired,sorry you had to go through all the experiments to achieve your goal of running right, it can be a pain. I hope the best on your conquest. In any dealings with these bikes, whither single/double or Oem be patient never giving up. What you experienced was just the opposite for me but took time to get the 32/36 dialled in.Good luck

The 32/32 people refer to is a Weber licensed Holley used on several US cars. New carbs for about $100 are available from stovebolt, tom langdon??. Others have used 32/36 or 32/34 with success however most who like them and stick with them use a 2 into one adapter which funnels the 2 barrels of the carb into a single opening for a one barrel. It seems lots of people who try and set them up as straight 2 barrel progressive using the VW TYPE III OR IV manifold report more success.

You would think it would choke down too much, but the reports of success are there. Another used pretty small runners (1") with reported good ride-ability.

This comment doesn't really prove anything, but the YouTube vids sure make them sound like there is more of a jolt of power when the second barrel comes in. I want to try one, but time and money are scarce.

I have a gl1200. I bought the single carb kit on ebay from Juan in ca. It came with a 34pict3 Empi.Never could make it work right.I complained to Juan and he is sending me another like I already had. Can anyone give me a source to get a different carb that will work right outta the box and fit my 1 barrel intake? I am getting pretty well fed up with what I have and feel a little screwed.Any help would be greatly appreciated. Thanks Dave

it can be done, but it is sometimes hard to better than engineering of many many hours and time the people that put time in to building these to start with. just my 2 cents. i even modify my ball caps. my wife once said you modify EVERYTHING.i said if they had have built it right the first time i would not have to. some times carbs can be NOT the trouble. again just my 2 cents.

life is good.
