Motorcycle Fuel Pump Testing: Honda VT1100

[@letmwhirl]

Thanks a million. I was searching for a manual, found one, then searching for the wiring to the pump and relay. After much frustration, i pulled up your video, then reached the section where you jumped the wires to the pump. The pump is working fine. So now I can ck the ground to the relay, and if it's good, then order a relay. I am working on a vt750dc black widow for my niece. This bike has been sitting for over 3 years. I just installed kits in the carbs and found that the pump was not kicking on with the key activated.

[@albertpfaff6686]

I like the knowledge you have on the subject of Honda motorcycles !!! You are straight forward… humorous at times and enjoy watching your videos… I always get something out of all your videos !!! Big Thanks for information that no Honda dealership would ever share with anyone !!! Thank you for your time and have a blessed day.

After a bad driver tore the front end off my Dyna putting me in the hospital with a broken leg I bought a 2002 Honda Spirit 1100. Had it delivered much to the delight of my wife.😮 Still on a cane. Got lucky, it's a hot rod gem. Well, after I massaged the engine a bit 😅

[@Spool77]

The fuel pump on my 1100 died at about 32k miles at about 10 years old. At that time I was having a hard time actually even finding a factory replacement that wasn't "refurbished" and also under $200. I ended up buying a Facet cube style pump and mounting it under the right hand side cover. It's been working great for the last 7 years and the bike now has just over 50k on it. If it ever does fail, it's a $50 pump and will literally take 5 minutes to replace. Facet is a well known quality brand though so I doubt I will have any issues.

[@gittyupalice96]

Just ordered the pump and filter for my VT750DCB from (bikebandit) the pump was about $110 and the filter was around $10. For what looks like the same exact pump and filter in this video. Thanks for the advice, I knew something was off.. but that just nailed it down for me. Mainly because I didn't know the bike had a fuel pump until just now lol, so I wasn't sure why it was doing what it was doing but now makes perfect sense to me.

[@fxrmike5145]

Can you just bypass the fuel pump for carbureted bikes? Running fuel line straight to that splitter?

[@davidsolomon9085]

Good job explaining how fuel pumps on these bikes work , not on easy job replacing them , just bought a vt1100 for my son for his birthday, it's a surprise, so I am going thru the whole bike , carbs , spark plugs etc ,I think I will test the fuel pump since it's a 2003 , keep up the good work , your earn a subscribe 👍

[@jimthvac100]

You suggested the old fuel filter was most likely the original. I wonder if you had just replaced the fuel filter if this would of pumped enough fuel. On the second test you installed a new fuel filter along with a new expensive fuel pump. I guess the only way to tell would be to run that old fuel pump by itself with no filter.

[@EnterpriseXI]

This vid is of great help. My bike (04 Spirit 1100) is dying every 2 or 3 minutes on highway speeds. I’m doing this as soon as I get home. I’ll update when I can

[@jtbasic]

Within the first minute you describe the exact issue on my bike, bogging down. I just ordered a new filter. Gonna try that first. Thanks for the advice for buying cheap amazon parts

[@TheMotorcycleMD]

Hope it digs up a solution!

[@Cpennington57]

I can attest that the Amazon pumps aren’t a forever fix. In October 2020, I replaced the pump, filter, lines, and rebuilt the carb. It ran great for a year. Only use ethanol free premium. I got married and life happened so I didn’t drive it for a year. October 2022 I was ready to ride again and wouldn’t start. Towed it to my new house and left it in the garage. This week, 3 years since fuel system replacement, I got back in there. Rebuilt the carb again, which appeared to have had some corrosion on the float needle which made it stick and I thought I found the problem. Just installed it and no start. I replaced the fuel filter, Amazon 2 for 1. First one leaked like a sieve! Immediately put the second filter on, good. No start. I listened for the fuel pump and there’s nothing. I’m pretty sure it’s been crapped out since October of 21, which means it lasted a whole year. Now I’m back at it! I need my bike running for a group ride on Friday, so I did just order an Amazon special pump for a quick 2 day fix. I have an OEM pump on the way. Needless to say I’ll be a master at pump replacement lol Your video was awesome btw!

[@RobertRemillet]

And thank you for the comments on chinese-made fuel pumps. I did just order one on Amazon for like you said 20-23 bucks. I'm going to return it. It's a pain to get to and I don't want to replace it twice. I will take your advice

I've been having this acceleration issue for a month now and took it to a shop. All they did was replace the spark plugs and rev it and say it's good. Picked it up and still did the issue at heavy acceleration where it pops and doesnt have ass to it anymore. Rides completely fine any other way I have the throttle but full. I will definitely have to try this fix out before taking it anywhere else! Thanks for the video man!

[@TomFromYoutube]

Mines having the same issue. It's fine until about 7/8 throttle then it cuts out all power. Hope a new fuel pump will fix it.

[@OtayBuckwheat]

THANK YOU 👍 My 99 C3 Aero wasn't ridden much before my back injury in 2009 and very little afterwards, so it only has 5600 miles on it, and it's beautiful. I had drained the tank and stored it in an insulated shop where it's been sitting since 2017. I had it fully serviced at a Honda dealership before I parked it, and I had to clean up the start button contacts to get it to turn over after putting in a fresh battery. First I removed the tank and checked the coolant level, because I don't think the dealership did that, and I swished around some gas and ATF and let that and a little crud drain into a into a jar for inspection, and also I removed and cleaned the petcock. I knew there had to be a filter and the fuel pump somewhere, and I knew that I needed to test several things in the right order for a proper diagnosis. I have a no start situation, but power and turning over isn't an issue. It's trying and it wants to run! The bike is 24 years old and it's been sitting for nearly six years so I'm sure the fuel filter looks much like this one. Now I know how to jump the relay to listen for the pump. I did turn off the fuel and I let it run completely out, so it wasn't parked with a lot of gas left in the carburetors and lines I knew where to come for more information, so thank you!

[@JB91710]

I think I fixed my no fuel problem on the non-running 2002 1100C I just bought! Relay! The pump wasn't running, insert the paper clip and now it does! Thanks for the video! Update. No, I didn't! New relay and the pump won't come on. Jump the wires and it comes on. There was a very small amount of gas in the tank and the pump might have been dry. Will the brain of the bike prevent the pump from coming on it there is no gas in the pump?

QUESTION...would a bad fuel pump cause a dead spot in the throttle about half way up....full carb rebuild done but when throttling up there is a dead spot and then past that there is ridiculous acceleration. The carb rebuild fixed a few problems but this one has remained...and yes there was bad old gas in the system before the rebuild which the reason for the rebuild.

[@russiantroubleyakutsk1612]

I have a Honda Shadow vlx600. When I get to 65-70mph it stalls. When I try to restart it, it will only restart when I simultaneously use the throttle and press the ignition button. Could this be a sign of a bad fuel filter or maybe a bad carburetor?

mate, lov your videos. helped me a lot already with my 30 year old VT1100. But i seem to have a problem and that is finding a place to buy original parts like the fuel pump or a indicator handle switch.. I find all sorts of other original stuff. Do you have ago to site?

What i measured with flukemeter with right ohm acording yamaha book prime/second coils startsplugs stator regulator its loading on battery 14,1 and up to 14.9v Fuelpump starts on and off as it should i suppose, if i take away hose from carburator witch is full with gasoline, it should start and run until gas is gone? Whats the problem? thanks

[@francescob5849]

So I did the fuel pump test and it’s pumping enough based on the 5 second test. My bike is still having issue with sudden throttle up. I did notice it throttles much better with choke partially on. So I’m gonna start messing with fuel/air mix screws to get it a bit richer. See how it goes. Anything else that might be the problem ? I did clean the carburetor and sync then the best I could.

[@brittanybattye985]

Helpful video, thanks. I'm having an issue with my VT1100 and I can't seem to diagnose it. Seems to run fine until I hit 80mph. Hit 80mph and the bike stops responding to the throttle. Let off the throttle a tiny bit and it sputters, let off to 70mph and it's fine again. Any ideas?

[@TheMotorcycleMD]

Did check what is mentioned in this video?

[@jaimeparadise]

I really wonder why some people delete/remove the fuel pump all together from carburetor motorcycles. I have a shadow 750 ace and wanted to know if it is best to remove it or replace the pump.

[@itzwilliam5051]

Here in Brazil, twin-carbs Shadows VT600 had a common issue on their fuel pumps, probably because of the bad quality of our gasoline, which deteriorate the pump's membrane and in some cases, set the bike on fire. My bike had a pump malfunction and I had this problem solved by just deleting the fuel pump and it runs great, just like when the pump was good... The only different thing that I do, is run the bike always with the tank on the 'reserve' position, because it gets the fuel from the lowest point of the tank, so it has a little more fuel pressure.

[@TheMotorcycleMD]

I can see how that would be beneficial on reserve. I would image that while you are getting closer and closer to the reserve, things can start to show the signs of fuel starvation?

[@itzwilliam5051]

@@TheMotorcycleMD Glad you replied to my comment! Actually, riding daily like I do, I never experienced any sign of fuel starvation... And all of my fill ups are between 7-9 Liters (the VT600 holds 11 Liters), so it is pretty close to the reserve.

Okay so i did the same thing you did on the carb tuning video, listening to the engine and i did open up those idle mixture screws a half turn. And it runs and sounds nice now. BUT i am getting some black smoke now. At the same time i also did sync the carbs. The sync was way off.

I have an 04 Honda Shadow VT100C, I never hear my fuel pump at all. But it runs fine, just hard to start when it's warm. Starts right up w/ choke I'm the morning but I have to give it throttle to start when it's warm. I don't understand why. I don't know if the carbs are flooded or if I have a lack of fuel. Do you have any ideas

My fuel pump doesn’t run unless engine is running.

[@elmerfudpucker3204]

I chased my tail over the entire winter on my 2000 Tourer. I ordered an Amazon fuel pump, put it on, it tested fine, but didn't fix the terrible bogging and dying anywhere off idle. rechecked the pump, tested well over what the factory manual said, so I just about bought Japan trying to fix the thing. Went through the carbs, replaced the stator, rectifier, coils, pulse generator, and even the ultra rare and expensive CDI module. Nothing made a bit of difference. Going back to the basics, I bit the bullet and bought the OEM Honda pump. Installed it and now it runs better than new. I'm forever sold on getting OEM parts for may biker now, if they are available. An expensive lesson I bought, for sure.

[@PainterD54]

Always add some Seafoam to the gas tank if you plan on not riding it for a month or longer. That will keep gas from gumming up the carb and fuel pump. If you need a new fuel pump, you just use a cheap automotive fuel pump rated at 3-5 lbs. pressure. They work great and will probably last much longer than the stock Honda fuel pumps, which are not made all that well. I've used several automotive pumps on Honda Shadows that I worked on and they work great!

I bought a new one ($200.00), after pulling the old one I said too much trouble and went old school and gravity feed it now. It doesn't need a fuel pump. I can still get it up over 130 mile per hour and get 100 mile before refueling Mo. Kansas border winds. I do lose about 1/2 gal. fuel capacity in bottom of tank because fuel goes below carbs My VT1100 it is not necessary. It doesn't like regular gas as well but your not suppose to run regular in it anyway (the sticker on my battery cover says from MFG) I ran the gas hose under the seat ($8.00 ft.(and fuel filter I can get to now with out having to tear down half the bike. Your video is good but the fuel pump was a dealer thing to make unnecessary money off of. I do understand the liability issues of making a video about that. I did find hose and wire management will work on that also to hide everything and put the fuel filter under the seat. I have 73,000 Miles on my VT1100 and put about 20.000 a year on it.

I wish they described this better but I think I did this correctly and no voltage. Book then recommends checking for open circuit, damaged connector. Connector seems fine. How do you test for an open circuit? And then clymer says checo ignition system subfuse, fuse contact, and ignition switch. Thoughts on what to rule out or likely issue? And thoughts know checking the ignition switch, not sure what Clymer is getting at when I check it? Working, not working?

[@dacunha69]

That's not the way that pump works, the half part with the diafragm has a solenoid and a switch, when the diafragm is puled in the switch it is open, no energy, and the spring will send it to the rest position, the switch it is closed and the cicle goes around. The other half has two valves, one for sucking the fuel and the other to send the fuel. As the diafragm it is pulled in it will causes a low pressure in the chamber and the fuel goes in, when the diafragm it is released the spring will try to compress the fuel but the exit valve will let it pass, Sorry for the bad English.

[@TheMotorcycleMD]

Ah, makes total sense, I didn’t think about it just being a spring loaded solenoid. Thanks for clearing that up. Regardless, still sounds like we can agree on how the pressure in and out accepts and pushes the fuel in and out repeatedly to build the pressure. 👍🏻

[@julianparrott]

Do you think it would be a good idea to replace the filter first and redo the volume test to see if the filter is just clogged ?

[@TheMotorcycleMD]

You could totally do that. The reason why I don’t is because I bottle feed the system applying pressure with my hand to force the pump to accept fuel. A clogged fuel filter resisting flow from the gravity fed tank vs an applied force on the container pushing the volume seems to do that trick and show the same results with or without a new fuel filter. Does that make sense? regardless, if the fuel filter is clogged enough to restrict flow by this much, either the tank inside is coming apart or the gas left in the filter has been left to gum up. Meaning the pump is gummy too, which means the carbs are probably nasty as well.

Does anyone here know for sure what the third port on this pump is? So have told me it's a vacuum line?

Cody, you save lives in the form of the money I save as a result of your videos haha. I can’t thank you enough for what you do!!

Would it run off only one cylinder if the pump is bad? My 98 vt1100 aero runs off one cylinder and then randomly kicks into two cylinders and the bike nearly leaps out of my hands...But now I can't get it to start at all?

Coils maybe

I have a 1999 honda shadow vlx 600 that has a fuel pump . I thought fuel pumps were added because parts of the tank was lower than the carburetor and a pump was needed to pump the fuel that was lower in the tank than the carb . On my bike there is no part of the tank that is lower than the carburetor . Shouldn't gravity be enough to keep all the gas needed in the carb to keep it going like it should at any speed ? Why do I have a fuel pump ? As far as I know the very next year 2000 Honda removed the fuel pump and didn't change any thing on the carb . So why did honda add a fuel pump to this bike in 1999 . If its not needed I would like to remove it . What electric parts should I disconnect if I can remove the pump .
