Here is the video of my bike before I replaced the fuel pump. It was very flat, had no low end torque. That hiss and the flutter slides went away with the pump also. I know the bike was idling high I still had the "choke" (fuel enrichment on) but, that had no effect on the issues it was ha...

There's the catch that caught me off guard. My old original fuel pump had enough flow to barely get by on but, there was just not enough pressure behind it especially since it has to be pumped up hill against gravity. If I remember right per the factory manual (which I have a copy of) my pump had th...

I finally found the problem to be the electric fuel pump not working well enough to get the fuel up hill to the carbs. That was after doing everything that you have up to this point. Now that opens up a whole other can of worms. Thank, Travis! I'll add a fuel pump flow test to the list of things th...

Also keep in mind (if my memory serves correct) the fuel pump does not begin to flow fuel until you push the starter button. Once the the engine is running and you let the button go the pump stays running. There may be an issue in the handle bar control. It is know that these bikes can develop loose...

I know that sound and chased that exact same problem for months! My wing had no low end torque until you got rolling, launching from a stop was almost impossible. I finally found the problem to be the electric fuel pump not working well enough to get the fuel up hill to the carbs. That was after doi...

I agree it may be that the return hole my be clogged. Also to remove air and bleed the system I like to reverse bleed the system. Take the cover off the clutch master cylinder and suction some of the fluid out. Get a large syringe, rubber hose and fresh brake fluid. Pull the plunger out and fill it ...

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 wh...

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 ...
