If my memory serves correct that hose goes to one side of the 3 way (one way check vlave) vacuum fitting for the flapper in the intake duct. It's on the left side of the air cleaner assembly on my 92 interstate.

Ideally the shop manual says to use a graduated cylinder to actually measure the output. You have to be careful because, your pump may still put out the right volume but not not sufficient pressure. That was what got me when the original pump went bad, volume was right but it did not have enough pre...

I wish I had pictures, it would make things a lot easier. Once you take the pump assembly out of the tank you cut the wires to the old pump, then remove the pump from the clamp. Put the new pump in the supplied rubber isolator, then put it back in the clamp (don't tighten completely). You will need ...

If you search you will notice that I have posted several threads on this subject. I have not had the greatest luck with aftermarket fuel pumps. I have personally gone through several pumps which were all built by Carter. I had one Carter pump last a few months, but the rest only lasted days or weeks...

I'm short too (about 30-31 inch inseam). To make things better for me I reshaped the seat a little (with a grinder and a flap wheel) and am now able to put my feet flat on the ground now. All I did was remove some material from the horn of the seat, bringing my legs closer together. Super easy, just...

Hey everyone, I have a question for y'all, I have bled the linked brakes on my wing twice now (first time was because after sitting for 6 years they leaked down) second time was just to see if I could get a shorter range of travel. I didn't get much change when I bled them a second time, it travels ...

I know I'm a little late here but, I have to say a wing with no mufflers but has the chamber intact does not sound bad. The original owner of my wing pulled the mufflers when it was new in 92 and put straight pipes on it. Fast forward to me it still has them on it and it sounds pretty good. You can ...

Started out pulling wrenches on over the road heavy trucks (including fire trucks and ambulances), did that for 12 years. Then decided on career number 2, been a full time paid firefighter/paramedic for 5 and a half years now.

I'll chime in here too. Maybe it was bad luck, maybe bad parts but I have had issues with Carter fuel pumps. They seem to never last long for me, don't really know why. I installed each one as it should have been for our applications and then they would fail all at different times. Now I don't pull ...

I have not had a chance to balance the carburetors yet as I have not had much chance to ride recently, that is on the agenda for this week. And in reference to the vacuum lines, I have replaced 99% of all the small lines. I got all of them from Honda because of size and bends, the only ones not repl...

Good afternoon all, As many of you have read I have some issues with the carburetors on my machine, that issue has been sorted and the seem to work well now. But now I have a new issue, when I start the bike regardless of how long it has sat it seems to have a stumble until it warms up. It is subtle...

An update to this thread, After stripping the offending carb no major damage or issues could be found. It sat apart on the bench for a short time due to lack of free time to put them back together. Once I got them back together and back on I decided to adjust the "choke" cable back some where it wou...

I know that the main needle should not be providing fuel at idle, which is why I asked about the needle seat. I thought it very strange as well, and watched it intently for about 5 minutes and I can easily see fuel running up the needle and a few drops falling to the throttle plate. In all my years ...

Hey everyone, As I said in my first post I have the bike running well right now. I noted an interesting find the other day, the main jet on the right hand carb is letting fuel by. It is actually a pretty noticeable thing causing fuel to puddle up on top of the throttle plate. I cleaned and visually ...

Good evening all, I have a question for those who know these carbs well. I have finally had a chance to get back to working on the wing this week. I have it running, just not running well. It's still a head scratcher. I know they are absolutely clean, I personally cleaned them and confirmed their cl...

Hey all, I learned some things yesterday. I have my wing running better than it has in a while. After looking over the carbs I decided to readjust the throttle plates. I adjusted them to be more open than they were. After that readjustment it ran to high as it is supposed to do. I did notice that I ...

I just wanted to bring this back to the top. This morning I was able to confirm I have no vacuum line leaks on my 1500. I used my home made EVAP smoker and tied directly into both the right and left intake manifolds and I did not see any visible leaks. Are there any other base line settings for thes...

Yup have looked at and replaced those hoses.

bluthunder31 yes it is, it's the same pump and person. After I first got this bike running it always ran very rich. The plugs were black (not soot covered), but just black. It also had a surge I was trying to fix. Last September I replaced that bad pump with the one that's in it now and it seems to ...

Can someone confirm my math for me. I have been fighting with my wing the last few months. It just won't run well especially at idle, and will not high idle at all. I checked the fuel pump output twice. At the carbs the pump put out 9oz of fuel in 5 seconds. Closer to the tank like the book says it ...

Sounds a lot like the clamp that holds the cable has gotten loose. There is a clamp on the front of the carb assembly and I'm willing to bet it's loose or missing. The choke mechanism is spring loaded and naturally returns to the no choke position. In order to get to it you are going to have to get ...

Isolators are brand new and actually helped fix the idle surge that it had. It may be a vacuum leak, guess I will check all the new hoses I put on. Also does the direction of blue vacuum T under the carbs matter? There is a black fitting on the T fitting, when I took it off I did not notice what sid...

Ok everyone I'm still in need of a bit of help. I still seem to be having an issue with fuel delivery, and I'm stumped by it. Even after starting it after it sat for seven years it ran right up on high idle and ran pretty well all things considered. In September I noticed that the bike seemed very r...

Gotcha. 2 turns out should make it rich then. I'll need to run them in a little then to cut back on fuel then.

Ok, so the pilot screws control air right? If this is the case then I suspect it is much too lean right now. So I'll start walking the screws in a quarter turn at a time till the high idle improves. This jives with my memory of the screws being less than the starting 2 turns out.
