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.

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.

[@nathanvazquez5895]

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!

[@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!

[@fxrmike5145]

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

[@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

[@andythrall7552]

Great explanation and presentation. Thanks for sharing your expertise. I’ve got a ‘07 Shadow Spirit that won’t start, so this was not only helpful, but fun to watch

[@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!

[@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.

[@akbarhussain1767]

Hi there Cody,Excellent demonstration ,on how to change the fuel pump & how important the Manuel's are,thanks again friend 🙂🙂🙂

[@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!

[@stevenvestal2893]

Thanks for the info. On fuel pump

[@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.

You are amazing, man!!!! That's the problem I have.... still learning so reading the manual step by step on how to diagnose and fix this issue.

[@OtayBuckwheat]

I come here before reading the manual.

[@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.

[@TheMotorcycleMD]

itzWiLLiaM Good to know man! I guess that’s one less part to worry about failing 😆

[@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?

[@JackerGR]

I am 100% agreed with you but if you can not find the original part ??? I have a 32year old yamaha and i cant find the original :/

[@MotoMango]

Thanks for sharing your knowledge man!

[@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.

[@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?

[@TormentedVet_Reactions]

I have an 04 1100c highway speeds, anything above 50mph, when throttle is applied falls dead on its face... new fuel pump, new fuel pump relay, carbs cleaned, rebuilt, and synced.

Fantastic video! This was very helpful to me as a first time bike owner. Keep em coming!

[@cjk100694]

I actually have a question as my bike is doing the opposite when I ease the throttle it bogs down when I gun it the bike will get up and go carbs are clean and synched

[@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. 👍🏻

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.

[@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.

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.

Going by some symptoms my 02 was having before it died on me last there’s a high chance I might have a fuel issue, gonna test voltage at the battery while it runs and see if that’s an issue but if it isn’t it definitely has to be the fuel system because when it died last it felt like I had ran out of gas

Probably not because that’s not something I would recommend.

[@lancerussell3605]

Question: Fuel pump won't start on start up, but when I jump it, it runs like a drum roll. Checking for voltage Clymer manual I have says "measure voltage between the fuel cutoff relay harness side connecter black terminal and engine ground". 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?

[@transformer889]

The diaphragm that you cut is the main part, the pump has two one way valves working opposite to each other, diaphragm by going up and down creates suction and pumping action and that is how it works. Pouring water in the electrical part is not a good idea, probably that was what doomed the pump by the way of leaking gas into the motor.

[@RedDelPaPa]

why not just let it pump for 60 seconds so your measurement is actually accurate? And, did you test the old pump after replacing the fuel filter first?

[@jimrocket3452]

Probably so you're dealing with less fuel but I would do a full minute and just pour the gas back in the tank after measuring it. Need a measuring cup. I also would've changed the filter and measured it.

[@abruptlyblunt]

i'm chasing a problem with my 2k vt750cd and i've run this test over and over again and keep getting 6 oz in 5 seconds which equates to 72 oz per min but that seems awful high for a 20 year old oem fuel pump when the factory min requirement is only 30.4 oz per min, does the 72 oz sound possible to anyone else???

Hi Cody. As always, excellent material. But I’ve been asking and asking and cannot seem to get clarification on the very simple question of exactly what you are doing with that bottle you’re feeding gas into the fuel pump with. My simple questions are as follows: 1) Where can the bottle you’re feeding gas into the pump be purchased? 2) How are you using the bottle and where are you routing that rubber hose that seems attached to the bottle? 3) Basically, I’m just looking for a bit more of detailed description of how you’re using the bottle so I can perform the same test.

97 shadow ace 1100... 14k miles. Come out, push button, no choke, fires first stroke, runs perfect. sits and idles great for 2-3 min, drops to 1 cylinder for maybe 10-15 seconds before it dies completely. And then it's done, won't crank again for a couple hours or more. I managed to ride it once, went 8 miles at 65-70mph, then dropped to one cylinder and slowed and died. And had to trailer it back. Any idea where to start? For the 2-3minutes it runs, it revs great. Can make a loop around yard riding it. idles great. All gas is new, drained tank and replaced it all with fresh. No change. I haven't had time to change fuel filter, or check spark plugs, or check for spark when it dies.

when power is off the pump stops but does it block the gravitation flow?

[@TheMotorcycleMD]

That’s actually a great question. Since whenever I have performed this test and the outlet hose is in a bottle. No fuel flows unless the pump is pumping. I’m going to say that it stops gravitational flow.

[@biranit50]

You should make the test again with the outlet hose hanging down. I know for sure that a windshield washer pump does NOT stop the gravitational flow because thw sprinklers are always higher than the tank so when I used one for a low hand washing gudget in my jeep I added an electric valve to stop the flow. If the fuel pump stops the flow I would be happy to uae one item instead of 2. Thanks in advance

Carb is dirty and needs to be fully Cleaned.

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 .

Hey man! I have a 78 Honda gl1000, runs great, but after doing a carb sync, it will dip below idle speed for a second then pick back up to normal, also, when slowly reving the engine it will stutter for a sec around 3000 rpm, but doesn't do it under load when moving, any idea?

[@TheCrusader2009]

Iv got a BT1100. Intermitantly it stutters we accelerating normaly when warm. Is this systamatic of the symptoms youv explained?

[@christianwalden9006]

just swapped the puel pump on my 96 ace 1100 is there a proper way to prime the pump before starting it

[@antonblast]

When it’s up there around 120 and I give it all it will do this but is this anything to worry about right now or can I just avoid dawging it out and be fine

[@jasonwillmafingerdoalbin2905]

What are your thoughts about changing from the 4 carburetors into 2 on 79 750 Honda SS. A witch 2 should I convert.

[@jasonwillmafingerdoalbin2905]

The housing to the gas/air mixture screw is 3 quarters totally broke off and missing. So I'm almost forced to go to a 2 carb set up. New carbs are at least 200 bucks and a most parts bikes are about the same. So I think this is my only option.

[@John-pd9zv]

I know you recommend OEM parts but Honda no longer makes pumps for my '92 VT1100C. Any recommendations?

[@francescob5849]

My Honda shadow “bogs” down only when I throttle up with the bike in gear (accelerating). It throttles and revs fine when in idle. I’m hoping it is the pump 🤞

[@dogone70]

you should have made a video on replacing the fuel pump :-)

[@jaredfrasher2724]

I disagree, although a second video showing how to replace it would be a nice addition but not everyone needs to replace it right away. Some people would like to know if they actually need to replace it rather then just assume they do and waste money buying something that might not be bad.

[@antonblast]

@@jaredfrasher2724 well said I’m here for the same reason mine bogs out at 120 when I give it full throttle but if I can avoid any work and just kee it under 120 then even better

Hey Cody, I have a question for you about my Honda PC800. I know, its a weird bike but I love it! So my question is about my clutch master cylinder. I recently changed out my brake pads and and fluid for the front rotors and also changed and bleed my clutch. My clutch has alsways been soft but consistently engaged. When I bled the air out and sealed everything back up, the clutch was nice and stiff. First time I rolled it out for a test ride, the transmission engaged almost immediately when I let my fingers relaease the lever. It felt great for about the first 30-40 mins of the ride. Then the clutch began to loosen and is currently back to how it felt prior to the work I did. Is this normal or should I start looking into pulling the slave cylinder and inspecting? Your thoughts?
