Pulled Weber dfta and replaced it with 32/36 off of a Chevy LUV pick-up....The bike idles at 1000 to 1100 rpm now, and purrrrssssssss up the road, with two on the bike it performs great,need to put a stronger spring on throttle,but all in all the "frankencycle" runs great...charlie g.

The manifold is one I made..I'm rather happy with myself because the darn thing works...I put a drawing on the 1 to 4 conv. thread....Charlie G.

I have some material left over from making the first two intakes,steel,I may build a few more. One will be going on the '77 I have that I'm building for my older brother. Now that I know the thing works and what carbs to get, the rest they say is easy. Charlie G.

I just picked up a Solex 30 Pict 2 and Solex 34 Pict 3 with a manifold that bolts to the 34 Pict 3 all for $30. Anyone use either of those carbs on a goldwing? I was hoping he would have a 30 Pict 1, but these were all he had. The manifold will only bolt to the 34 Pict 3, which is a little larger. That would probably be the easiest to mount up. But maybe theres an adapter to mount the other carb to it as well. Both have electric chokes. Any advice on these carbs would be great. Hopefully one of them will work. When I decide which to use, I'll get a rebuild kit for it. I'll get some pics later.

  As you can see, the 34 Pict 3 is a bit larger. Maybe better? I think they can be a bit more difficult to tune. I've heard some rivet close the hole in the throttle plate..So maybe I would do that when I rebuild it. Since it bolts to the intake, I'm leaning towards that one. Obviously I'll have to cut off the exhaust tubes from the intake, and trim the tubes down an inch or so.. Still a bit larger, will be interesting to see if I can make it bolt up.. The intake also needs to be sandblasted out. A good amount of rust - but I think it's still solid. Actually..Heres an adapter so I could run either carb on the Solex 34 manifold: http://cgi.ebay.com/ebaymotors/VW-Solex-Carb-Adaptor-30-34-pict-_W0QQcmdZViewItemQQhashZitem35aaef7ba3QQitemZ230501088163QQptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories Maybe I'll grab it in case the 34 carb doesn't work out..

Are you familiar with the Solex carbs? A great place to hunt Solex stuff is: http://www.thesamba.com/vw/ ...good prices, but you got a good deal if the butterfly shafts are tight and carbs are complete. The type-3 manifold may be less of a headache for you in the end. Just type "solex" into the searchbox. Adapters, carbs, manifolds, linkage, etc...

I've spent the evening googling them and been learning.. Advance Auto will have the rebuild kit for the 34 Pict 3 tomorrow. $18 From what I've read - I've decided to fill in the throttle plate hole, and leave the jet stock for an initial fire up. That will make it slightly richer and should allow for a smoother idle, less of idle stumble. Check the plugs as I go..I can always very slightly drill it out. The choke and throttle are both free and snap return quickly. Hopefully its not too gunky inside. I'll sodablast it out. Test the float, etc.. One question I do have is, do I need a 12V supply to the electromagnetic cut off valve? Not sure what that is exactly..Never seen one on another carb. Other than lawn mowers where when you close the throttle, it grounds your spark. Edit: I think I understand now...I think it is required as a 12V key on +. I guess it shuts off fuel to the motor to prevent "dieseling" or running after turning off the key. Last edited on Sun Jul 25th, 2010 03:18 am by Tom2 |

Yes.. 12V+ key on. It shuts the idle circuit completely down. It's actually a jet set-up in a flow/no flow kind of fashion. PICT-1 = one carb circuit PICT-2 = two carb circuits PICT-3 = three carb circuits The new repro H30/31's are knock-offs of the Solex 30 PICT-3... I would use the PICT-3 between the choices you've shown. You can search the Samba like you can search here. There is enormous information on Solex carbs there. Many knowledgeable Solex fellas here too though. Old Bug-heads.

Yea, I am simpyl amazed how much info there is out there about these carbs. I certainly don't need to buy any type of manual! lol Everything you'd ever want to know is online.. Hopefully I can get some garage time in tomorrow and see how far I get. I'll probably try to get the manifold mocked up first, then go ahead and rebuild the carb.

PS - You're "filling in" the throttle plate. Make sure that doesn't affect a circuit. It's there for a reason. And I retract the PICT-3 useage. I thought it was the 30 that was a PICT-3 and not the 34. You may find the 34 to be hard to get a decent idle from, so I would go with the 30mm PICT-2 instead.Sorry if I confused you in any way. I've benn out most of the day and am just now finding my dinner.

Yea, I think I'm still gonna try the 34 Pict 3..If it doesn't work out, I'll get the throttle plate adapater, and use the 30 pict 2. Supposedly filling in the throttle plate hole helps with idle, otherwise the hole is so big, it just ends up not wanting to idle low with that much air leaking in. Also causing a lean idle/off idle condition. I'll be happy just to get the bike running with a single carb..Anything is progress at this point. I can always revert to my 30 pict 2, or find a 30 pict 1 if needed. Wouldn't be much more work or money.

Ok. Keep us filled-in on what you experience with it. Slowing the air and lowering the volume may or may not load the carb up, I never tried it. The higher the PICT number, the more the circuits, the more efficient the carb will be. I like efficiency. It equals power output in my book. I 've tried a handful of Solex carbs, from 28's up to the H30/31. They can all be tuned to run a GL, and each will have its own characteristics with idle, response and overall performance. Fuel mileage will vary drastically depending on where you set your tune. I have a set of 35PDSI2/3's that I haven't tried yet. A left and right carb set that will be a tuning challenge I expect, but may be worth it. I don't know yet. I'd really like to know how that 34 works out for you. I stayed away from it because I thought it was too big. Good luck with it.

The DGAV/EV 32/36 Weber is working great on my GL1100,still have to figure out a manuel choke,wired mine open for now. Put new Dunlap Touring tires on last night,the old ones were weather checked and had been on there for 10+ years,a bear to get them off. We're going to take the "frankencycle" out and see what kinda mileage I'll get and proformance is there on the hills with two up...Enjoy the day,Charlie G.

Hmm..Well, it looks like the intake is gonna be too long to work. I don't think theres enough room to put a 2-1 Y splitter in there. I wonder if theres exhaust flanges that are the same size/bolt pattern as the Solex 30 or 34 carbs?

....don't tell anyone I showed you that.  When you get it all tuned and squared away, run this under it: Attachment: 0903_hbkp_21_z+power_adders_for_the_street+radial_discharge.jpg (Downloaded 158 times) Last edited on Mon Jul 26th, 2010 12:41 am by CaptainMidnight85 ____________________ "They're gonna make it look like suicide."

That would be sweet! If I was looking to blow this sucker up! lol Which I may want to someday, who knows lol I think I'll be able to make the manifold work. I was able to cut off the excess metal, and break it off. Then I trimmed the pipes back. I also grabbed some PVC from Lowes. Need to replace the rubber coupler with a 2 1/4 to 2in adapter for a tighter fit..But otherwise looks like this should work good. Only bought enough parts for one side, can get the rest tomorrow. I really dont feel comfortable using the PVC and rubber..but, without a pipe bender and welder..This might be the best I can do. Maybe once I get it mocked up, I can take it into a good welder and have them make me a metal version with exhaust pipe. Theres also a hole in the top of the manifold that was probably used for an EGR valve or something. I tried to tap and put a bolt in it, but the steel is too strong. I can just have a shop weld it for like $5. Also have to bend or notch the bracket that goes across the frame. You can see it highlighted in red. I think I can just bent it back slightly for enough clearance.
