This is a NOS condenser unit that I bought for a bike that I have since sold. I bought it on ebay, and its still in its original packaging. I just wanna sell it to make my money back. $25USD plus shipping.

Hey everyone, same thing as last time, I ordered another new gasket and it wasn't exactly hard to find, but it wasn't super easy so I thought I would scan for my own use and thought since you guys may eventually need one and like making your own gaskets here i would post up the scanned image...

This 1:1 scale, is listed as 1L9-15461-00-00, GASKET, CRCS CVR 2, on the Yamaha Parts list. If you print it make sure you print it as 100% (actual size) and it should fit on nicely on a normal sheet of paper. I had to order it for myself, and just picked it up and i know you guys all like...

I have been really getting into adventure biking, and since my XS400 is the bike I have i figured i could do my best to make it as capable as possible. Obviously i don't mean anything crazy, but there is no reason these bikes can't hit some dirt trails, fields, or mild terrain. I know there...

This is just a link that i found (rather easily) that i thought would help out a bunch of people on this site in terms of Carb cleaning, rebuilds, repairs, and general understanding of what the carbs do and how they do it. It shows a Suzuki bike, but the carbs are the same as on theXS400...

Just noticed my tip has broken off my left side idle mixture screw, i can't seem to find a place in Canada that sells this model of mixture screw :/ I need one! Someone PM me if you have a spare screw or know a site that sells them, this is all that stands between me and a running bike! Ahh...

I have been what i thought to be a vacuum leak. - It will rev all through the range in neutral but when riding it wont get passed 3k in any gear - I have check the vacuum lines and intake boots and carbs and filters and got nothing. When i removed the vacuum line from the petcock it was...

I picked up my 79 xs400-2F about a month ago, and the PO gave me 1 key. I would love to have extras of this for obvious reasons but i have taken it to three places that specialize in cutting keys and none of them had blanks and told me they couldn't replicate it. Does anyone have a source...

Hey everyone, i was just wondering if you can swap electrical components between the years? I have a 79 xs 400-2f and I am looking for new relays (the flasher and the safety relay that sits up by the front fork under the tank) I am having some trouble finding these online in Canada for...

When you build a custom bike (I am not talking accurate restore, just something with some work for yourself) do you typical remove the center stand? I can't seem to be able to put my bike up on my center stand consistently or easily, and i was thinking that if i never use it i might as well...

So i have been really looking hard into my issues with my headlight, Neutral light, and gauge lights and last night i was trying to clean all the connections i could - I undid the connection, blew it out with some compressed air and sanded off the connectors of any corrosion/gunk/etc. The...

I just finished up my Carb work, and decided to check my spark plugs. I pulled out the right side plug smoothly, it looked good, i had no trouble putting it back in. I pulled out the left side smoothly and it looked good BUT I went to insert it back in and started screwing it and it seemed to...

This method just worked for me, after about 2-3 hours of thinking, and trying multiple things it was actually VERY simple once i thought of it, and hopefully it will help others. NOTE: The lessoned i learned was always use penetrating lubricant before even attempting the removal of jets or...

I am new to this but when I opened my carbs up I easily found and replaced my main jet but found a screw screwed tightly into where my pilot jets should have been. I removed that screw and found both pilot jets stripped... Anyone know what that screw was doing there? Is that normal and how...

I know there are thousands of these threads, but since buying this bike the PO said "The headlight, gauge lights, and neutral lights are burnt out" but after changing and testing the lights, i found that the lights were not the problem. I did find this random plug under my airbox that doesn't...

The previous owner of my XS400F told me he 'convert the brakes to DOT 5" brake fluid... Is there anyway i can confirm this? and also what what does this conversion consist of? I just don't want to dump in DOT 5 fluid into the brakes and have something horrible happen to my bike :S

Carbs are generally a hot topic on here and I saw this in my service guide and thought it would help out some people. This is an exploded view showing a 1979 and Earlier XS400 Carburetor. It is from my Clymer Service guide. This manual makes note, many times, that 79 and earlier model had...

I was wondering if this has ever happened to anyone here. I am canadian, and ordered some things from xs650direct and then Parts n more since xs650 was out of stock (however they ship from the same address and are owned by the same company? ) Anyway, today i found the delivery slip...

Hello to everyone, as the title states i just purchased a 1978 Yamaha XS400 for my first bike. I have been looking around for used bikes for a while and was reluctant to purchase such a vintage bike, but for the price (the guy is even delivering it tomorrow), and the fact that this site...
