Yamaha XV535 Virago - Recommissioning (Part 12) Carburetor Removal, Full Clean / Service, and Refit

- In this twelth part in our video diary of the recommissioning work that we're doing on our 1997 Yamaha XV535 Virago project bike, we have a second go at sorting the carbs, by removing them, servicing, and then refitting.
We'd previously cleaned them in-situ but on our test ride, we found that she was mis-firing when the choke was off, and the throttle was released.
This is a lengthy video as we try to include the process of removing the carbs and the very tricky process of refitting them.
Hopefully, you can find what you're looking for in this video, especially the not too well covered subject of the airbox intake rubbers.
They fit around the airbox with two rubber flanges. To remove them, you need to push the lower flange up in to the air box, and then the carbs are easy to slide out.
To refit the carbs, you need to slide them in and then push the lower flange back out of the airbox, as you slide the rubbers over the carbs. The front rubber is not too bad but the back one is tricky unless you have real small hands and very strong fingers.
If you know of a better technique then please let us know. There is a guy who trussed the rubber up with string but it did not work for us.
Anyway, we've got her back together and she fired up easily and ran well...now for the next test ride...

Thank you for such a steadily recorded and well narrorated educational video. This was a life saver.
Glad it was helpful!
Thank you soo much, showing the whole process😍
Glad it was helpful!
the 2 air breather vacuum lines go to the housing of the chrome side bulge/bubble. one side hold electronics, the other side is the breather for the carbs.
Thanks for this information we shall take a look
I think the main reason screws get butchered on Japanese bikes is because people don't use a JIS screwdriver (and use a Philips instead, which effectively drills out the middle of the buggers).
Yes, that’s a real problem
Do you have to empty the fuel tank and reserve tank before working on the carburators?
Not sure I have to remove to carburators or just take of the sides..as on your first video on working on the carburators. Thanks!
No you don't. You'll want to make sure the fuel is good, if it's been stood for some time. You can service the carbs without removal and you'd definitely want to try that, first. We had to replace some small diaphragms that did require removal. Removal is not fun!
Yes I just saw that in the video, the rubbers are hard to get in place at the airfilter. Thanks so much for the tip and video! 👍🏻👍🏻👍🏻😎 @@MotorcycleFettlers
I have a leak in the front carb on the side that faces the front wheel any ideas on how to go about it complete new to this btw
If it's the o ring on the inlet manifold You may be able to replace it without taking the carbs completely off, if you are dexterous enough. If it's an air leak or is it a fuel leak then more info required.
@@MotorcycleFettlers so the drain screw was loose but its running very rich since my plugs where pretty black also when i accelerate fast on high rpm it would sometimes make like a pop sound any ideas ?
Am i blind, i cannot seem to find the main jet mixture screw.
I found the idle mixture screw behind rubber caps, but cant see the mains.
It may be that there are variations between models and regions but as far as we know, the mixture screw is the one behind the plug that's it.
Excellent video! I just got an 87 535 and it hasn't run in over 2 years. I have spark and fuel delivered to the carbs,but no fire. I removed the carbs today and cleaned most of it out,but after watching your video,I realized I missed the jets inside that part. Guess I'm taking it back apart tomorrow and do it right. Thanks, Mike from Georgia, USA
What are the wire conectors for
I think you're referring to the carb warmers. I don't know if they were still working or how much benefit they bring.
🇧🇷🇧🇷🇧🇷👍
Thanks for your feedback.

I know nothing about English, but I watched your video several times, and that's why I feel safer doing this maintenance on my 535. Thank you.
Does anyone know where I can buy the carburetor new?
I'm sure new, old stock NOS turn up on eBay from time to time. I'd imagine that they are expensive. Maybe it's worth asking Yamaha if they're still available. CMSNL are a source of hard to find NOS parts. I'm sure there are other companies.
Please stop calling them Philips screws, they are J.I.S. screws.
J.I.S (Japanese Industrial Screws) screws NOT Philips, Philips screwdrivers will chew the screw heads up.
We do try to remember to say JIS. You're right that there's a big difference and that using a Phillips will mangle the screws.
