Carb Fustration ... Wondering what to do

hmmmmm there are many here who have the dft 32-32 carb setup and type 4 vw manifold set up ...i have this set up on hooch but with a slightly bigger carb ...it is a monster of power ....this carb works like a four barrel muscle car of the 60s... id say it has the best potencial of power

there is also vw single barrel set ups ... i have some experience with them but not much ... the little i do have seemed like they will work good too as the one i set up on a 1100 fire up instantly ...after cranking away first with gas valve off and then again with kill switch on ...LOL just a wee bit to much beer in the mix.......

one thing for sure is it works good if one stays with it ..to get it right ... much better than stock carbs period in my book ....but others think differently .....personally ive never been on a oldwing that is as fast as mine is ...dkl has a thread here on a quite cheap and doable pvc manifold ...thats quite well thought out ...as the dft is too ...time to read some threads ... others will chime in i am sure...LOL there also faster typers :smilie_happy: :smilie_happy:

Yes I'm going to switch to this weber carb when time and money permits for more top end, the reason I didn't go that route in the first place was because the manifold cost more, and re- jetting required and drilling and tapping the vw plenum. Not complicated stuff but I had neither the tools nor money. Vw /pvc setup was half the cost too.

I already have my weber carb and its rebuild kit, need the buy manifold parts and figure out jetting and buy a tap and die set. Then I'll have both setups, vw carb can be my backup... What you give up with the vw carb is top end at 85+ or high rpm acceleration. Vw carb is more of a low end torque monster cruising setup, the weber a high speed whiplash machine.

As of now I'm not looking for the fastest or most powerful just the quickest set up that has the best chances of being a plug and play.

If you are going to the trouble to change your carburation set up I believe that you are better off starting with a brand new weber carburettor otherwise you may as well stick with the original carbs reconditioned. The weber 2 barrel has the ease of serviceability and with a little tweaking ( correct jetting) it will be perfect. Unfortunately atm these carburettors are set up for a different vehicle than the GW and need the necessary changes to make them perfect. Maybe in the future you will be able to buy them jetted correctly for a GW application but as with anything that is plug and play you pay the price for that convenience.

On eBay what manifold should I stay away from if I go that route?

 

[dan filipi]

Agreed, go with a new Weber from Stovebolt.
$95 plus shipping I think.
This way your not dealing with a used worn out carb that was probably someone else's headache before it was removed from whatever it was on.

 

[mespock]

How much plug and play and how much modifications?

I wouldn't have spent that kind of money to put on a vw carb, so even though I seem to be the only person that likes the vw carb I'd suggest stay away from all of them. Too much money, not worth it.

If you won't diy a PVC manifold and arent willing to try a chinese copy of a vw carb or rebuild a used one go the new weber route.

I did have a lot of little issues because I used a used carb and rebuilt it, but even after all those issues I chose a used weber also. Both my carbs were less than $20 shipped.

Pretty much every variation seems to work but if you have doubts on one you find. Post a link to it and get some feedback from the guys here.

I only suggested buying new based on just about every used and rebuilt carb I've used in the past which were already worn out and leaking vacuum at the throttle shafts.
That's not always the case but for under $100 to be assured this won't be the case, is a steal.
I'm not saying don't go used, just know the potential for problems is higher just like a worn out stock rack.

$90 for new carb, $50 for vw manifold, $25 for grab bars, some tubing, some clamps, Your done for under $200. Sell your carbs, maybe $100-$125. Several good write-ups here. Mine are still stock, but as soon as they give me grief, that's what I'm doing.

You leave out air filter and some type of throttle hookup...somewhat expensive new jet costs unless soldering and drilling or the cost of drill bits and solder and propane to solder with if you don't have those things, and the reccomended 2-1 barrel adapter to center the fuel charge in the manifold. These little things all add up too.

My costs were less than half that, under $100 total, and I sold my 83 rack for $240 shipped so made money switching.. I put the extra money I made switching over into a gasket kit and newer water pump and a couple other things.

I didn't put an air cleaner on the vw carb yet but its 50mm and round which means any 5$ ebay pod filter fits. The weber will require some customized air cleaner modded to fit and a means of attaching it, more like 25$ and some more work.

Its more work and money to actually do the weber than mine was by far. Then again long term I didn't save anything since I'm headed down the weber path too.

sounds to me ,like some one should make a full, ready to go, bolt on single carb setup. and sell it as a kit. it would need to be a proven setup, that works. for myself, i am a bit of a stock fan. i kind of like playing with lots of carbs..... :smilie_happy: sort of. but i do have an idea (in the future) for a single carb , turbo or supercharged unit. :moped:

I don't have problems going with a new carb and that's what I figure I'd do. I just would like the well maybe at this point what would be the easiest and less trouble some solution. I just want to ride this thing for a season then do some more tweaking and have more fun.

mespock, what is wrong with your stock carbs?
Maybe you can get buy with just a cleaning?

 

[joedrum]

there both good alternatives over stock rack ... this is not to discount stock racks ...its more to to discount extreme lack of parts and high cost of parts that are availible ...and the failure rate of rebuilding stock racks to be reliable

 

[slabghost]

Since it has been running well with the rack you have. I was wondering if you've tried ATF in the fuel and turning the fuel off before shut down as suggested earlier?

He had leaks and is looking at a full rebuild kit to get the stock rack going.
I had considered trying some kind of liquid gasket on mine to fix leaks without a big investment but I wasn't sure if there was any that would last for gas.

I understand the read thing and I have been going through a few threads. But as I'm learning I am also asking questions to those who are willing to share and answer some questions that I still have. I apologizes to those who's skills are far above mine but I am green when it comes to some carb things and I learn better when I am in conversation. So please bare with my questions.

I have run some sea foam through them. I believe they had been running fine until I flooded the engine about a month ago. This is when I noticed the leak. Since this time the leak has gotten worse.

Bike ran great from early June to Mid August. I haven't used any ATF as I was also told that sea foam was as good as ATF.

I do appreciate the conversation and suggestions. I am just trying to find the best solution that fits my bank account and my mechanical ability. As I said I am not afraid to turn a wrench. Just want to make the best choice for me.

Last year I fitted a set of GSXR carbs to my 79 750K. Project worked great. Had a fantastic online coach and some good reading from the CB1100 forum.

There seems to be a lot of discussion on the single carb here and finding the right thread and getting through all the in between talk for me gets a bit confusing. But I'm muddling through it. I am also in the mean time responding to post and asking questions as it seems we have a nice conversation going here.
