    I installed the better engine yesterday. Several issues. Drain plug was stripped. Helicoiled it. Removed side cover to flush the aluminum chips and found the small oring between the the case and cover was mangled. also, banjo bolts only had 1 copper gasket each. Adjusted valves. All were tight.

    Anyway, started right up! Checked oil pressure to head, and took it on a 10 mile ride with no problems!

    Doesnt have the thin metal gasket between valve cover and head. I hope that doesn't cause me grief. Prior owner rode it a lot so here's hoping.

    Not super impressed with the rebuild, careless builder fwit. But she's alive and sounds very tight.

    There is a reason Honda made that gasket steel. It acts as a spacer for the cam center journal. This is from a XR600 I worked on recently.

    Gotcha I have one hanging on the wall. I will replace it before I start it again. And pray the journal isn't already doa. It changes valve clearance too, right?

    Yes it does. You will need to apply sealant to the gasket or it will leak like a pig.

    I will... most likely will get to it this weekend. The XR600 can have the valve cover removed w/o removing engine, correct?

    I spent a couple of hours trying to get it off without removing carb and intake, thought I might save you some furstration. :eek1
    Did get the cam out without removing the gear, not so hard when you don't care! :lol3

    There WAS a gasket, SMH. However, this little plug had obviously been bouncing around in the galley/valves/ who knows where, for who knows how long... The plug is in the end of the Camshaft so unless this is an extra, that's not it. Could it have travelled up to the head from somewhere else?

    I sealed the gasket, reassembled, adjusted the valves and took out for a ride. However Oregon is in the middle of a storm so it was a short ride. Ran good tho, just like before. Still, where did that plug come from?

    So, I finally got my licensed basket case 1986 XR600 running perfectly (and looking darn good too, I think) as of this fall. However, in the process I ended up with a whole bunch of parts including a running but smoking engine and a bent frame. I have every part available to build me another one except for a frame, a piston and rings, and a little machine work.

    As of today, 1/09/2014, I bought a 1986 XR600 red frame for 75$ off Portland Craigslist (thanks Mike, who btw, has other parts available). I'm going to build up another bike! This one doesn't have a title, and will be created out of all the 'lesser' parts, but will, with any luck and a little money, be a good runner and should carry someone around the bi-ways of Amurika! :)

    First step - clean frame with simple green, clean the oil tank with solvent and then maybe some paint.

    pictures to follow... :D

    Here is a shot of the angle difference between the wrecked white frame and the unwrecked red frame. :eek1

    I bought it this way but the story is is that he hit a 4-wheeler.

    I think he got in to the reconstruction project, bought new used forks etc, but then realized the frame was DOA.

    Hey Lands,
    I'm looking for some stuff for my 87 XR project. Do you know if Mike has a brake caliper for an 88 or later XR? What else does he have? PM me his number if you can.
    Thanks,
