- Step by step video detailing removal and re-installation of the carburetors on a 1997 Yamaha XV750J Virago. Should apply to most models of Virago including the 1100. Older models with Hitachi carbs should come off in a similar fashion.

I have to clean and rebuild the carbs on my '98 1100. This was very informative on how to get the carbs off/on. Thanks!
Very well done and explained video. Thank you for having a second person for the camera.
Absolutely, the BEST video for Virago carb removal and install!! He clearly explains what he is doing, while he is doing it, all in an organized process. I watch this every time I have to work on my carbs. He also has a carb disassembly video that is just as important. I wish all videos were as well made!
I used a new metallic brush to take the rust off of the cable springs. Comes off easily then compress them and wipe off the cable with some carb cleaner. Only takes a few minutes for that chrome look to come back
Good stuff my dude! About to do this to my 750 this week! Trying to get ahead of the game so I'm ready when the weather warms up. Thanks!
I don't usually comment much on these diy videos, but I have to say, very good information. You explain well all the little tricks to remove items and catch the things that fall or want to fly away. And family friendly too, God bless and Thank-you.
Good videos! But, I'm amazed at how over-engineered those carbs are! It expresses how much patience one must have to work on them! Lol.
The 10mm bolts in the center can be loosened with a 1/4" ratchet and a six inch long extension. Put the extension past the vacuum lines and then put the socket on. It's about a thousand times easier. Great video though. Thank you for your efforts in making it.
Good one! Thanks
too bad mine uses allen wrench bolts, seeing these 10 mil bolts looks so much easier than a little allen wrench
Great Video, I have the exact same bike and year, everything is identical.
Anyway, I'm getting ready to rebuild my carbs (rear plug is fouling out after one tank of gas along with the resulting misfire and backfiring) What I'm curious about is that you mentioned silicone spray to help get the carb back into the carb intake boot. Can you also use the spray to help get the air duct elbow back on to the other side of the carb? Or is there a chance that excess spray could end up getting sucked back up into the carb gumming it up after I just cleaned it?.... thanks
This video has been my go to video since starting the carb rebuild job on my 96 XVS1100. A good portion of the 245k views are probably me.
There are a couple things that tripped me up though. On my bike, the bolts that go through the slotted portion of the carb boots are incredibly difficult to get to. So I had to carefully work a 1/4" drive 10mm socket, on a extension and universal joint in between the two carbs. A real pain, but I got it. Another thing that tripped me up (and am ashamed to admit) is that the two carb boots each have a hole where the vacuum lines hook to. When I took mine apart, the nipple and all came out so weeks later I'd forgotten that and it took me forever to figure it out. There was one thing that the video didn't mention - probably because it's obvious to everyone but me. When reassembling, before you get the carbs pushed back into place, make sure you place the fuel line (the portion that has a braided covering) in between the two vacuum chamber covers at the top of the carbs. The vacuum line that splits off and attaches to each carb can lay over top of the fuel line assembly quite nicely after that.
Boys and girls if you have never done this job before, (like me) make sure you take plenty of pictures - and from different angles - as you are disassembling. I did, but managed to miss angles that would have been quite handy indeed.
Great video though. Thanks!
Getting ready to pull my carbs off to clean on a xv750 I just bought, this is extremely helpful to figure out the vac lines, etc. This guy sounds just like Dan Aykroyd to me also, I love it.. 😂
Thanks to you, I was able to pull, disassemble, clean, reassemble, and replace my carburetors on my 1984 xv1000. I've never done anything like it before. And OMG those inner rear intake bolts took me HOURS and a wrench I had to bend for the purpose. Thank you!!
Crystal Kent you should make a video I have. A 84 1000
You can use a socket on those. It's much easier.
please make some sort of vid. struggling with my 85 and looking for help!
oh yes , the bent 10 mm wrench :)>
Great vid. Thanx.

Great video, nicely and calmly explained.
hello from Israel :)
Thank you! My Virago was not running at all. Would not accelerate. I'm the least mechanically inclined person you ever want to meet. Usually when I try to fix something, I don't get it fixed but I break something else in the process. Took the computer out to the shed. Followed step by step this video and your cleaning carburetors video. Just got back from a ride. The bike is running so smooth.
THANK YOU FOR DOING THIS VIDEO!! Helped a lot.
You've made a mistake. When you take them out, start at the front boot. The reason for is that you have more space to work at the front carb. Once you took the manifold out, ( only one screw needs to be removed), you can pull both carbs aside to have more space to get the rear one out. I've done mine twice. And when you put them back in, do it vice versa.
Excellent video. Wanted for nothing. Well done. Regards from the uk.
Thank you Very Much ..regards from Thessaloniki Greece
Got a question what does the breather plate do on the rear cylinder head cam sprocket?
Thanks for the video instruction. Just completed the cleaning of my 1996 Yamaha XV1100 virago. Runs great!
I installed on it but is leaking gasoline on the right side from the hose on tap of carburetor the one with black filter you called brither tha one is open
Thanks for the video. This was EXTREMELY helpful, informative, and easy to follow. Can you do one for removing the swingarm?
Sold the bike a while ago, so I can't sorry.
Awesome video and very useful!! But I have a question, what's that pump you have inside the left air filter plate?
that would be the emissions system, basically it just pumps air from the carbs directly to the exhaust. Somehow it passed the emissions requirememt even though it does nothing to dilute the exhaust
A little tip I learned from an old carb master- heat up and bend a 10 ml combo wrench to fit into the space between the carbs and you can loosen those two boot bolts easier :-)
Yep, that’s what I did
I've had 3 or 4 Viragos, 750 and 110, loved them, hated removing and installing the carbs, sometomes I used a 1/4" ratchet with an extention and swivel going from the front to get to the rear carb mount screw
I need help! So I followed this video very closely as it is the closest one I can find that fits my problem.
The AICS or whatever he called it under the left hand bug eye cover has two nozzles one marked F the other R. (Fuel and return lines I'm assuming.) There were no hoses connected to these on mine. I am happy to provide pictures if needed but I have no idea where they are supposed to go. Can someone provide me a video link or some details that will help?
I’m am so frustrated I can’t find anywhere that shows the cable being out back together as much as I watch your vids to help rebuild my bike how dare everyone over step the cable 😢😢😢
hello very nice video . what tipe of carburetor is this i have an virago 750 from 1994 and its looks like mine and i wana tune the fuel mix but i cant find the pilot srew. im a newbye this is my first bike :)
👋 was wondering, do you know why gas would pump out the lower gas tank driver's hose when taking off the top tank? The top had some in it so I pumped some out took off the hose from top tank and it started pumping out gas fast, it pumped almost the whole lower tank out.
Great video.
What a labor intensive bike to work on! Have both a Vulcan and a Virago, it's over an hour difference to pull the carb off these.
Thanks
Is there carb on could put on a 92 virago 750 I’m looking for answers for mine??
Just got my virago it seriously pops when I let off the gas so I’m watching this prepping for a carb clean 😢
Man I would forget we're everything went after I took it apart thank you though I'm going to be doing this sometime soon
Hey is a nice video that's help me but I have question
I cleaned my car same bike it works but now it backfires some times what's wrong?
Another awesome and very helpful video from u sir! Thank you!
I just got a junk '89 750. Rebuilding it and I'm not sure where to get the parts, specifically the carb, I don't know what I'm looking for as I've never done work like this before. Where would a good place to look be?
I'd try ebay, that's probably your best bet for someone parting out a bike. If you can grab a complete set, you should have what you need to begin with.
Thank you very much well detailed
I got another question where is your rear spark plug wire coming from and going to
Brilliant tutorial. First time I have done this work and this enabled me to complete the work. Thanks.
Great video. However I have a problem with the fuel pump on an 1100. When starting the engine it pumps fuel out of the brether line. If I set my thumb on to the brether line the pump stops. Do you have any advice to give me?
Diaphragm shot
Could this work on a 535? I would assume it’s close to the 750
What’s the black wire that has white on it coming from the bottom on the other side where it’s at go to
Very nice video.
I thought it was easier.
+zardportugal It gets easier after a few times repeating the process. I was making some jetting changes so I did this about 5 times total. Thanks for watching!
Cheers.
+ShortMag270 hello buddy,can I jump start my virago 1100 to my 12v corolla battery?
Yes.
Gracias!!
OMG...I wished I would have seen this video before I took my carbs off......this would have made it soooo easy !!! Thank you, thank you,...for posting this. you are a GENTLEMAN, a SCHOLER and a Judge of Fine WOMEN !

Did you have to sync the carbs after doing this?
I didn't see you tighten the most difficult bolt from rear cylinder(what was tricky to open). That was what I was waiting for to see, because that bolt makes me loose my mind. Good video though.
What is your air mixture screw set as how many turns out.
Hey did you end up putting in an inline fuel filter?????
My 1996 virago 750 starts but shuts right off! I had the carb rebuilt and still not staying running I’m lost if you can give me any suggestions I’ll appreciate it
Have you renewed the float seals? How are your diaphragms? You can easily check them without taking the carbs off. Take the breathers off ( The black lines that go to both carbs and blow air from your lungs in. The slides should easily open. Id they don't, you might have a hole in your diaphragm, or it's not seating well in the groove. I had to do that six times with new diaphragms that they sat right. Did you synchronize the carbs after fixing them? The fuel/air mixture, or sometimes called pilot screws should be turned out 2.5 turns from soft seat. Another important step when doing these carbs is setting the floats right. There's the so called "clear tube method" where you can see from out side when the floats shut.
Michael Mersi okay I took the carb off but didn’t get to it yet ima check everything you mentioned and synchronized no I really don’t know much about carbs at all dude but I am gonna check everything out thanks again
hey thank you man my 96 was giving me a hard time
I have an 82 750. Cool lil bike.
I know this is very late to the party but I have an '89 xv750 and see the same weird differing bolt lengths all over the bike. It seemed like instead of going with one size they had a special length bolt/screw for every single hole on that bike
So the vacuum line has three lines. Can someone tell me where the three connects to?
Thanks for that video. I'm planning to remove the Carb from my 1996 1100. Will it be the exact same thing?
What a godsend. My first bike, and it wasn't getting above 2000 RPM. this helped me get the carbs off and cleaned. Awesome video has my bike running!
My 1994 XV750 uses Allen head bolts instead of the 10mm hex head ones in your video. The center ones (which require a bent wrench etc for the 10mm heads) can be reached with a long 5 mm Allen wrench reaching between the carbs from the front or back. The 5mm wrench in the Harbor Freight 69084 set is long enough. anything shorter, or much larger on the handle end, won't work.
I have two questions, did you use a non-vacuum petcock from a Banshee? And does the 750 use a fuel pump or is it gravity feed only? Thanks great videos!
Had to get another perspective in getting these out since I'm doing a swap from the previous owner who failed to rebuild the original engine and simply put in another plant with a dubious repair history. I doubt the engine will go into the frame with the carbs already installed, so am planning ahead. Thanks.
Hey man great video!! I have a question I'm hoping you can help me out at 6:50 you remove a vacuum line. I'm currently working on my virago 750 and there is no vacuum line there (looks like it's been removed) I'm working on the carb because it has backfire issues I'm trying to resolve. Could this missing line create any issues there?
Thank You Very Much! The key to my conundrum was your revelation that the top bolt hole on each of the manifold boots is SLOTTED! 💡
Thanks for the input!! Going to try it in the morning. CRb vacuum lines
I am about to do this - remove and clean the carbs, fix it back up to get on the road as the heat cools down (in Texas). It has been a good bike for the last 20+ years. I plan for it to keep going for a long -long time. Thanks for doing this video. Just seeing it done give me hope I can get through this.
ive never worked on a bike before, let alone rebuild/reinstall a carb, but thanks to you and this video i was able to get my 94 750 running mint again, thank you so much for helping me through this headache, you sir are a scholar
Awesome video! Thanks so much for the detailed view! Does any other virago owner know where to get saddle bag brackets? This gentleman has awesome bags and looks like he also has brackets to hold them in place.
Great job...thank you for the life-saving effort! Certainly was very explanatory! Kudos!
This is an awesome video for virago carb removal and installation. Ty so much
Thank you for the video. I just bougth the same bike this summer. Can you tell me please what are the two ports I have to use to sync the carbs? I assume the two neples one on each boot but no sure.
Thanks again and keep making those helpfull videos
This has been very helpful. Very straight forward procedure and presentation. Thanks!
Working on reinstalling carbs on an 85 XV1000N and they had already been taken off. I had nothing to go off of for the vacuum lines but this seems like it should help immensely. Thank you! I will update on my progress later.
Great job you are the man

Thank you for putting together a tremendous video for what is probably the hardest part of working on a Virago.
Thank you! Working on the exact same bike. Great video!
Thanks for this informative video,
I had an issue last night and I like your opinion or info from anyone else about my calamity.
I have a Yamaha Virago XV750. It is parked in my garage and I didn't use it at least two months.
This early morning I was woken at 5 o'clock by my screaming cat who is sleeping in the garage. When I went to the garage to check what was going on, I smelled a very strong petrol/gasoline smell! It turned out that my whole gasoline tank was empty and on the garage floor. The tank was full before. I think a full tank is over 10 litres! I quickly moved the bike outside and saw that the gasoline was dripping from under the carburettors. It took hours to clean up the mess, and the smell of gasoline is still in the entire house.
Question is now what caused this issue and how to fix it. The bike wasn't touched for over 2 or 3 months. Fuel hoses seem to be ok. I have to do a thorough check the coming days/weeks.
As far as I now know the fuel/petrol tap was on PRI . Today I was looking on the internet for answers and it seems that the tap should be in 'ON' or RES position. I normally drove it in PRI...and left it in that position.
Anyone who has some info is welcome to reply.
Thanks
Never leave it parked on pri. That means prime, and leaves unrestricted fuel flow even when the bike is not running. The virago does not have an "off" position. The fuel valve is vacuum operated, and should stop the fuel flow when you shut off the engine.
Yes. That is what I read today :-( I thought PRI = primary and than RES is the secondary fuel stock. But...what did cause this issue?
@@DuitenTeller The fuel leak is caused by the floats not sealing properly in the carbs. When the fuel level gets too high internally then fuel pours out the overflow. You may also want to change your engine oil as there's a good change the oil in now contaminated with gasoline. In the future just leave the petcock in the "run" position and this shouldn't happen. I said shouldn't because sometime the petcock goes bad and doesn't stop the fuel flow which results in the same issue you had. Some people change the vacuum operated petcock for a standard one with an "off" position, but then if you ever forget to turn it off you have the issue. My advice is make sure the vacuum petcock is in good working order and leave it alone, unless you need reserve.
@@Constantstate OK. Thanks for your extensive answer. Still, it seems strange that this happens after more than 2 months of parking. Why so suddenly? The rubbers / O-rings or whatever are gone / damaged / partly solved? The bike is from the year 1995. I am not hte first owner.
@@DuitenTeller Yes quite possibly an o-ring or needle and seat issue.
you rock thanks
Where does the petcock vacuum line hook up? I'm missing a tube on my XV750 that connects to the vacuum port of the petcock. But I can't figure out where it attaches to on the carb/intake
Justin Mills It should connect directly to the carburetor boot on your front cylinder
Thank you for this video.. Hello from Italy! 👍👍
Is this a 750?
This reminds me of the Good Old days of TH-cam
Awesome I have that job to do very soon. Your video helps a lot.
Excellent vid, thank you.
pena que a yamaha não fábrica mais a xv 1100 a minha não tem essa torneira de combustível como a a tua que facilita bastante a manutenção ! abraços brasil .👍
Really appreciate your video and efforts! I also have a virago 750, only bit I'm confused about is I take off the bug eye and have that assembly underneath and the tubes but no ais or whatever it is called? Worried previous owner just removed it and this is why i have acceleration issues with it just suddenly dying.
the AIS is just the emissions system, it is virtually useless. A lot of owners remove them, and some of us cap the old lines with .45 bullet cases, they make a perfect fit. The acceleration dying is not from the lack of that system, we have 5 Yamaha V-stars (the newer version) and a Yamaha Virago all with that AIS removed, they all preform fine.
great vid, can u tell me if the xv 750 virago has a fuel filter as normal, i didnt see one anywhere in your vid, my bikes been stood for 6 yrs and i found i have rust inside my tank, i eventually started the engine , it went for a bit like 5 mins, but next day wont start,-nothing, just lots of spinning on the starter and back firing, ime thinking some crap from inside the rusty tank has got through, ime hoping there is a fuel filter clogged but i cant find it , any ideas ??>.
thx-dave in the uk,
There's no filter that I saw from factory, but I put a small inline filter in the line from the tank... see video at 15:40 but be advised the one you see was too big and I have to put a smaller one in, such as this one... www.rockymountainatvmc.com/images/prod/275/v/visu_inlinefilter.jpg
nice walk through man. it's hard to find good videos on the viragos
Does the same process applies to the 125cc 97 model?
oh boy looks like a pain in the ass
Thank you...from italy
Hey nice video. I just got one of these that was a family members, he was a Veteran and I wanted to get it up and running. We dont have any keys for it, could I still do what you did in this video without the keys? regarding the carb ( so I can take it off and give it a good cleanin) Still unsure on wether to call locksmith or just buy aftermarket and try taking the old locks off
Try finding some old Yamaha keys... maybe a dealer. They old ignitions weren't too picky sometimes. I accidentally started mine with a snowmobile key once. If you take the helmet lock into a smith, they can make you a key though. The carbs can be done as in the video without a key.
Appreciate the tip. Sadly, the ignition was a different key so I had the locksmith unlock everything else, and make me a key for the ignition. But as far as this article goes, I am about to do this now! watching it again for reference.
Which items will be better replacing
Those viragos already have a fuel tank behind the rear cylinder.
Huh? What do you mean?
Great vid. My vacuum line is stuck to the carburetor and it won't disconnect. 6:40 I tried using pliers but it's damaging the side of the hose. I'm thinking about using a flathead screwdriver to pry it open or some w240 to loosen it up but I don't want to damage anything. Any advice?
Maybe try warming it up with a hair dryer to soften the rubber. Be careful using solvents on rubber as they can deteriorate it.
@@Constantstatewon't the heat make the rubber stick even more?
@@malikbenachour3511 it should let you move it around enough to break it loose, just don't overdo it.
if the tubes where not tight would that cause a gas flooding or a back fire ?
Flooding is more likely a float issue and backfire could be a plugged jet, emulsion tube or a carb synchronizing issue.
Thank you for this!
