Hello all, I just picked up a 82 xs400s (i believe) 14w on the engine. Think i got it for a good deal. Fully rebuilt motor (never been run), new tires, new batt and a plethora of parts and 2 extra engines! All she needs (so I'm told) is an ignitor. Can't wait to get her up. This would...

All right, what's the difference between these two bikes? I'm having trouble sourcing parts for the DOHC XS400, but it looks like the XJ Maxim is actually the bike I'm working on. Ways to tell the difference...?

Just got a free bike from my brother. He claims it is an XS400. The VIN is 1J3-200300. Did some searching around this forum and it says the bike is an XS500C/D but I can't find a year. My brother insists it's a XS400 though. Can anyone help identify this bike and the year? Thanks

hello, I'm totally new to motorcycles, and being the type of person I am, I have to dive in feet first. I've look at several "project bikes" on craigslist and saw one that instantly appealed to me. however, I don't know for sure what kind it is. From my research I think this is a 1980...

I have a copy of the Yamaha model ID chart and thought it might be helpful to the rest of you if I posted it.

Google didn't help much with trying to find the code for my 1982 DOHC in Purple. Any clues from the peanut gallery?

There are 2 bikes that I am looking at and I want to make sure I can use the psw hardtail on them since they look different from the other xs's I have seen. Neither have rear springs. I want to make a bobber out of one of them. Also will the TC bros. sportster tank fit on them with no...

Working on cleaning up, and dialing in, this recent purchase. But I'm having trouble pinning down the specific year and model. The plate says, mfg date of 7/80, but I don't know if that makes it an '80 or '81 model. The serial number begins with 4R4. This list over in the history section of...

Hi... I`m searching the year of manufacture of the XS400 G, H, SG and SH. Is there anybody here that can help in this?

hi everyone, i just picked up my first road legal bike, an 82 yamaha.....something. I traded it for my old Yamaha 225DX 3 wheeler, so i think i got a fine deal. Its been in storage since 2002, so it'll need some TLC to get it back on the road. According to the previous owner it was running...

I had a guy drop off a yamaha 400 in front of my garage, because he liked how I bobbed a xs650 last summer. but theres no paper work and the dude said he got it from a scrap yard. The side covers and some small stuff is gone, but its in way better shape than the 650 I did. So anyway I need...

What all Carb Tops can fit on xs400? im looking for some chrome ones...

So I've done a little digging and couldn't find much on the history of the XS400. I thought it would be nice to have a place for people to compile what they know about the XS400. Things like what years they were made, model designations, differences, VIN numbers for each year, colors...
