Single VW Carb

Post by acruzer1000 » Mon Feb 26, 2018 4:41 pm



Hi! I presently have two 1977 GL1000's. One runs great and the other always seems to have carb issues. They have been rebuilt twice by me and I'm seriously thinking of getting one of those VW single carbs. The one which I'm thinking of is VW Type 1 EMPI34 PICT-3. By VTC Motors. My question is, does anyone recommend using one of these and if so, anyone out there with experience using it...worked...not worked...or keep dreaming, one carb setups on GL1000 suck? Thanks, appreciate any feed back. Happy riding!

I did it because of the stock carb issues. I got a new solex off brand. and fabricated a manifold. I tried for two months to get it running but finally gave up. Some people have had good success but after trying many different jets it was a no go. It would idle but would not perform on the road. Kept on fouling the plugs. After five minutes on new plugs they came out black and sooty. I went back to stock after a rebuild kit and maybe ten times on the bench I do have it running 80% good. My bike is a 75 GL1000. I do think the carb was too big. It's for a 1600cc engine. You might have better luck with the smallest VW carb. Some have had good luck with two carbs. One for each side. If money is no object having them rebuilt is a good way to go but with shipping it was about $600 for me. I only paid $750 for the bike.

Thanks biker art for the reply. I just didn't want to throw money away if I didn't need to. I'll just keep troubleshooting this thing. I was getting close to fixing the issues but just wanted to skip ahead to save time.

Hi,

I installed a single pict 34 carb and manifold, and got the bike running fairly well. As the previous reply says maybe not as good as you’ll get if you finally get the original carbs sorted, however after a lot of time and effort I unfortunately gave up.
The main point I’d like to make is I had a lot of problems with VTC. I ordered a carb and manifold from them, the carb arrived bent, and the manifold never arrived and they could not provide tracking information. I then went through weeks of hassle to try and resolve to no avail.
I ended up with another carb and nicely fabricated manifold from a guy in the US on eBay. I can share details if you ever need them.

I now have other issues (see post) but I guess it keeps us busy!

Regards,

Chris

Hi there
I just changed on my GL1000 a single carb (34 Pict-3 Carburetor for VW) and I have some problem with it, maybe somebody did the same thing and can help me with that.
Well the problem is: I dont know how and where to connect the electric choke and pilot cuotoff solenoid.
And do I need to connect the carb to be grounded?
I tried to start it but is blowing out the fuel by carb, like is getting too much fuel.
Thanks.
Any pics or information will help me.

I wired both to ignition. Cutoff isn't needed,it just shuts off fuel when not in use. It can be removed an plugged. Choke is needed . an must have power when the bike is running. Good luck,I gave up and went back to stock.
