    For Sale - 1977 XS400D and many extra parts!!

    Change the Head or wiring

    Well, I was able to drill out the plug and and get the cover off. Just ast you said, it looks like everything will fit just fine. That's the good news, the bad news is that I started to look over the rest of the motor I bought and found that the housing for the kickstarter is cracked... badly...

    Change the Head or wiring

    That's what I was thinking originally, but then I saw the brass plug in the right screw hole. Should I just drill that out? Also is the end of the cam shaft the same length?

    Change the Head or wiring

    A couple weeks ago I posted a video of an engine knock I had in a newly rebuilt motor in my 1977 XS400. It was determined that there was end play in the crank that was causing the knock. At some point I may rebuild this motor with new bearings, but for now I just want to ride the bike...

    The motor was seized when I got it. Never heard it run.

    1977 XS400D engine knock?

    The bottom end is from a different motor. Not idea what the miles are. The bottom case, crank, gears and pistons are from that different motor, everything else is from the original motor which has 5500 miles on it. The original motor was sitting for 30 years so all the oil turned to a soild...

    1977 XS400D engine knock?

    So after further investigation, the noise seemed to be coming from under the side cover on the left side (where the starter is) I took the cover off and have found the source of the noise. The crank seems to have a little play. If I push and pull on the crank it moves slightly. It does not...

    1977 XS400D engine knock?

    The noise to me seems to be coming from the cam cover on the right side, but I know noise can travel, so who knows. Also, when the noise went away under braking, it was in gear without the clutch engaged. If I engaged the clutch while braking, I would still hear the noise. So I do not think...

    1977 XS400D engine knock?

    I did not get new pistons and rings. I am sure that it is possible that the engine is sloppy. I guess that I will have the mechanic look at it and if it ends up needing the engine rebuilt again, well....... we shall see. :( I'm not sure if I want to dive into that again. I am hoping that...

    1977 XS400D engine knock?

    Thanks for the input. I have not synced the carbs. I think I am going to take it to a guy who specializes in vintage bikes to check them out. Fine tuning carbs is an art that I have not mastered yet! I thought it could be an oil issue, but I rode it around last night and if I applied...

    1977 XS400D engine knock?

    So my 1 year resto-mod project is done. It is running, riding, titled and registered for the first time since 1982. It seems to run fine, but I am getting a tapping or knocking sound when I give it a little throttle. It doesn't seem to be affecting the way the bike runs, but before I ride...

    Too much fork oil???

    Sooooo... I had a very soft front end, after reading some posts here I decided to drain what fork oil was in the forks and replace it with some 20w fork oil. So I drained the oil by undoing the drain screws and leaning on it until it seemed to be empty. Then I removed the top caps and added...

    carb questions

    So I am close to being complete with my restoration on my '77. I have rebuilt the motor and fitted tin top carbs from a newer model on it. It is running, but I have been having issues with the idle. Initially when I got it started it idled normally, but after it warmed up a bit, the rpms...

    Is my bike correct?

    I have a 77 as well that (was) exactly the same as yours. Yours looks bone stock. I have the same gray alloy wheels and front and rear disc brakes. And on the 77 the exhaust goes back to end of the rear wheel. I think its the same exhaust as the old Xs360s Mine was original and stock when I...

    Master Cylinder swap

    I actually went to my local dismantler and got a used stock part. I will post pics of my complete restore at some point. I need to load them to photo bucket or something. Thanks! Posted via Mobile
