Welcome to bykrmom's Virago F.A.Q. Project   

Frequently Asked Questions about Yamaha Viragos

Many of these questions have been answered with more details in the Virago Tech forum areas, but I will list the question and the short answer here, with my own comments where applicable. Otherwise, you can search the knowledgebase of the forum and get the complete information on the specific question you have.

It has been brought to my attention that the wonderful background used on this Virago FAQ was created by David Denowh of
'Yamaha Virago TCI Ignition Module Reconditioning Service'. He created the image for his website.
I was unaware of this fact when the image was emailed to me some time ago, and I want to give credit where credit is due.

Please read this disclaimer if you haven't already.
Also, please take a moment to read the credits I posted, if you would.

Q. I have an ('81 to '83) Virago, and the starter solenoid has stopped working. The stock replacement is around $50.00 from Yamaha! Is there a similar, less expensive solenoid available that I can put in it's place to get me back up on 2?

Multiple Part question and Answer

Q. We'll start here in response to: My oil light went on for few seconds when I started my bike this morning. I immediately shut it off and tried to look through the sight glass. I couldn't tell if any oil was showing or not.

Q. This part next in response to: I put my finger down inside and couldn't feel oil. Perhaps that's fine.

Q. And lastly: I added about 2/3 quart of 10W-40, but I'm not sure if I see oil in the site or not

Q. Is it safe to add fuel injector/carb cleaner to the gas on my 82 750?  I've had people tell me no, and some tell me yes. The reason I'm asking is that I had an 87 FZ750 and put that stuff in the tank and one day BOOM.

Q. Would the fuel tank off of an 87 750 fit an 85 1000?

Q. I would really prefer to learn something about wiring a bike from scratch, because all I used was the running gear and engine from a Virago so I don't need all those bells and whistles on mine. Do you have any resources for something like this that you could point me to?


Q. The paint job on my bike is getting pretty ugly...let's face it, the bike is [x] years old and it would cost more than it's resale value to have a professional paint job put on it. Where can I find some do-it-myself info on painting it?


Q. I keep hearing about the AIS system, and that I should disable it and remove it. What is it and how do I disable it?

Q. I was reading about how to remove my triple trees in the Clymer manual I bought. It ways there are a whole lot of loose ball bearings in there! Providing I don't loose any in my driveway, can I reuse them? Is there a better bearing so I don't have to mess with the loose ones?


Note: The following question was posted in Virago Tech recently. This is a good example of why, unless you know and trust your local shop technicians, do most if not all of the work on your bike yourself.

Q. The front-end of my 1982 920J is extremely squirrelly when cornering. It feels real weak and not like out of control because I can handle her with a little bit of difficulty. I've done the axle, new tires, etc. and practice (at first I thought it was just my inexperience) to no avail. I've taken it to the only two shops who still work on older bikes in my area. In both cases I've been told that nothing is wrong and that the problem they 'think' I have, is that it's just the way these bikes are. I can't help but think that the guys at the shops are full of it. Is it true that the front-end weakness I'm feeling just a problem the 920J has like the shops say and if so, has anyone addressed this problem before? 


Q. I'm interested in getting some fork braces, but can't seem to find one to fit my 920. Any idea who might have them?


Q. What if I read this whole #!@%$#@!! FAQ and I didn't see an answer to my question?
