frame

I'm new to the motorcycle world and recently acquired a 1979 XS400. It needed carb work and some other odds and ends that I am still tying up, but one thing that I recently realized is the lack of a grab rail. I've been browsing around trying to find one that looks like what I'm trying to find...

Howdy, just wondering if anyone out there has mounted a King sportster tank (3.1gal) vs the standard 2.4 gal sportster tank and has any pictures? Cheers, T

What frames will work for 1984 yamaha xs400 seca parts? Are all the xs400 frames the same? Or are any the same?

I have a 76 Yamaha XS360. Are the 76 XS400 Frames basically the same bike? There is a needle bearing swing arm conversion on MikesXS that is listed for a XS400 and I would like to update the old brass bushings while I have it apart.

I see a large hole running laterally across the front of my engine block, just underneath the exhaust manifold. It looks like a mounting point for some crash bars, but I can't say I have ever seen crash bars on a sportbike before. My question is: Is this a crash-bar mount, and if so, what...

Hi friends, My bike got caught in a parking-domino collapse that including several other bikes, and my tail light assembly broke to bits, taking a bit of the fender mount with it. I think I've sourced the tail light but no fender yet. Any ideas? I have a black 1983 xs400. Like new. (And new...

I just bought a 1980 400 xs as my first bike. And it appears when someone put on the seat they put it on a little crooked. I was wondering what was the best route to fix it? I was thinking about cutting it, sanding it, painting it, and rewelding it. But like I said its my first bike and I...

how important is the rear upper bolt? I failed to photograph all the mount points when I pulled the engine(and everything else) off the bike. Now that I am placing the engine back in, I have a problem. I see where the lower back bolt, the lower front bolts, and the upper bolts attach but...

I bought what I believe to be a 1982 Yamaha XS400RJ Seca a couple weeks ago and am finding it difficult to find parts for. So far I know I need my gas tank fixed (previous owner let it rust then did some shoddy repair work), a new exhaust system and tires. I was wondering if someone could help...

Hey, I just bought a 1982 xs400 seca and the gas tank is no good. The previous owner tried to fix it by JB welding it and putting a liner inside however it didn't work and now the liner is flaking off. I was wondering what someone else's thoughts would be on fixing that and also if I was to...

Has anyone used a Dime City seat on their xs400? In particular the original Dime City café seat. Been looking at getting a café seat for my XS, and the dimensions of that seat looks pretty good. They are out of stock right now....Spad

Hey guys. I was wondering if anyone knew anywhere where I could pick up a decently priced aftermarket windshield.

Does anyone know if the fender from an xs400 Maxim will fit an 81 xs400SH with a 19" wheel. Or if there is a good option for the front fender with a 19" wheel installed. I have installed Maxim wheels, but now need a fender that will work. Thanks,

Hi guys! I´ve got a question for you. Hope someone can help. My handlebar lock probably doesn´t work, or at least I couldn´t make it work so i wanna remove it and see what is wrong. But how am I supposed to do it? It is i believe the, so called, Neiman lock (got 2A2/1977) which is in...

Anyone know if the xs400 handlebar mount on the top tree the same Center to center as an xs650? I want to use a set of riserless bars that are made for a xs650. Does anyone have a measurement for the 400? The xs650 is 3.93″ center to center

Hey guys! I've got an 1980 xs400 and planning to relace the front hub with 18x2.50, What is the widest tire profile the forks will allow me? I was hoping 120/90-18?

Found this great video on youtube for installing bronze swingarm bushings (very thorough), hes doing a xs650 one but it all applies for our bikes too. He installs a grease nipple in the middle of the swingarm which I think is a worthwhile mod, im definatly going to put one in too.

Hello all, I joined some time ago after lurking for quite a while, but haven't posted until now. I am beginning a rebuild but have not, as of yet, really settled on the direction it will go and have therefore not yet started a build log. In the mean time I am doing the things that will need done...

How have you guys mounted your fiberglass seat pan? Do you make a metal seat pan first? Just looking for some ideas

Trying to mount a custom single speedo on my 83 maxim 400, but the speedo cable wont clear the headlight bezel or key switch. Was thinking of getting a 90 degree cable adapter, which looks expensive according to ebay... wondering if anyone has ever gone this route? Looking for any tips or ideas...
