Fixed the oil leak, adjusted the clutch and brakes. Only thing left is to find a right foot peg rubber and replace or paint the front brake lever. Here are some pics and a video of it running. Hopefully this video link works.

After a tear down and rebuild that took just about 1 year, I started it this morning and was able to take it for a ride. It started after about 5 or 6 kicks with no choke. Of course there are some items that made themselves evident during the ride, but overall it ran great, idled smoothly at...

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.

I've been putting the 400 back together all winter and getting close to being complete. Can post some pictures as soon as I complete my last major task - paint the tank and side covers. This morning I installed the tach cable and gave the motor a spin with the electric start to make sure the...

I have the 80 SG model which has the 16" rear rim. When I ordered my tires, the charts said a 130 was the max my 2.5 rim could take, and I read posts where 130 would fit on the 400. The 130 is too large on my bike. I'm thinking that the swingarm and brake stay are maybe smaller due to the 16...

Anybody know how to remove the shrouds that cover the upper section of the shock springs. I like the looks of the spring that goes all the way up to the upper spring retainer. The best I could find was that you compress the spring but it didn't say how the shroud is removed. Does the shroud have...

After checking around regarding the smaller sealed beam headlight, I decided to go with the 7 inch headlight installed in the stock bucket (less the inner ring). I got my inspiration from a thread on the Yamaha Owners forum in a thread that included posts by Houghmade. The 7 inch sealed beam...

I'm starting to put back together my 400 and, while torquing down the swing arm bolt nut, the end of the bolt snapped off! Looking at the end of the bolt that broke off, about 75% of the bolt was already broke! If I wouldn't have pulled the swing arm to clean and lube the bearings, I would have...

I have been running NGK BP7ES's in my 400 per the Haynes manual which, in the ignition chapter, says that all XS400's run BP7ES. However, I'm looking thru the Yamaha Service Manual and I just read that the Standard plug is BP6ES. (It also lists the BP5ES for "Hot" and BP7ES for "Cold"). Now...

Found on Craigslist this morning. For 50 bucks I got: Turns out the seller lives less than a mile from me and put some of his 650 stuff on Craigslist. He was about 80% complete with hardtailing and chopping his XS650. It was a work of art. Right now I'm in the put back together phase of...

Hello everyone. I was pleasantly surprised to come across a forum for the XS400. I have been working on a 1980 XS400SG and thought I would start a build thread. Here are a couple of photos of the beast as I brought it home. Many things wrong with this little guy. Pulled the motor for easier...
