    How To: Install an Oil Pressure Gauge

    How to raise the rear end of a 81 tank?

    I want to raise my tank so it would be level with ground. I have some ideas but I thought that maybe some of you guys have already done it and have found some simpler ways how to do it. Original mount is a bit lower and it makes it look weird in my opinion.

    Converting to kick only

    Hi gang, Haven't been on here in a couple weeks as I gave up hope on the bike for a while. Since I've not received any bites on my ads yet and have cooled off, I'm thinking about trying a little more surgery to get her going. As I mentioned in my last post, the starter chain was...

    Oil Leak

    Okay, so the 1979 XS400 that I'm working on has been leaking some oil. I checked it out and it looked like it was coming from inside the sprocket cover on the left side. I removed the cover and it looks like an oil bomb exploded in there. So I think I'm on the right track. I had a 1979 KZ400...

    Removing Seized Brake Caliper Piston

    Hey guys, Tried out the grease gun trick yesterday to remove my terribly seized caliper piston. Came out like a dream! So much easier than trying to use compressed air, heat, channel locks or whatever! Here's a quick little video showing what I did! Hope it helps. :):cheers::bike: Clicky Click

    oil change question

    Hey there, I'm really new to motorcycles (and really, anything to do with an engine) and I recently got a 1980 xs400 special. This past week I went ahead and changed the oil and filter. The manual suggests 2.4 quarts of oil if you are changing the screen, so I went ahead and added 2 quarts and...

    '79 looks good but doesn't run right

    Helping a friend get the '79 xs400 running right before I officially buy it. Swapped in a new battery, fresh fuel and oil, but it still won't run right. It revved up really good with the new battery and all, but finally bogged down and died. Every start after that sounded weak, even with the...
