Only the top case is painted, hot oil make silver paint change colour.
Get a 1/4" drive set from Lowes for 'pretty cheap' or even just get 1/4" drive 10mm long socket and 4"~6" extension, no need to grind on anything plus it's way easier to get cam bolts torqued up properly later on
Cam bearings and cam looks perfect, the spalling is a manufacturing fault and not related to oil feed (although it's a REALLY good idea to do all the oil mods while you have it in pieces. What are you doing with stock CJ tank or is it already sold?

Are you seeing the pic?  His cast is off somehow.  There's isn't clearance between the screw head and fin to fit a socket or wrench.

Yes there is, the counter bore for bolt head doesn't hit fin although right side is real close
Thinwall socket is all you need as max torque is only 9ft/lb (although they are almost always tightened to 12~14ft/lb)
1/4 drive long socket  with extension is also the easiest way to 'not fuck up' cam bolts
Sorry for all the edits, grandson pulled the 'H' hey off laptop keyboard so it doesn't always work and I rarely notice until after I post something

Thanks for the tip(s). I'll take a look at Lowe's and see if they have any thin wall sockets; I have lots of tools, but nothing that will fit over that bolt without hitting the fins.

...I guess I need to do a search on 360 oil mods, eh?

yup, guess you do.
If you hang on Trek will probably post all the links for you  ;D (or you could find his 360 blog, it's all there)

What are you doing with stock CJ tank or is it already sold?

I have the tank, gas-cap lid, etc. sitting in a box in the garage. The whole bike was painted brownish red, over the stock color (which may have been a similar burgundy color) by a previous owner, but I'm not using these parts. They're dry and sitting in a box until I decide to start parting bits out.

If there's anything you're interested in from a CJ360, let me know. ...not much is being reused.

Also interested in what people use for fender blanks (front & rear) to cut down to size. The OE CJ fender has creased edges running lengthwise and I'm not sure I'll like that look on the front, and certainly wont' match it on the rear; looking for something with a smooth, round profile. :)

Thanks again guys.

CJ fender won't work,  I used part of one plus a Maico Enduro one on one of mine. ( had a Maico 490 MX/Enduro Alpha 1 at the time with a few 'modified' parts, 130mph  MX bike isn't sensible , even by my standards ;) ) May be easier to adapt something completely different or get hold of some CB parts?
I'll PM you about tank

Thanks for the great info PJ.

Good news on my front though, after taking crap from a buddy for "having every damn tool in the world" and not being able to remove the head, I dug into the old toolbox and put this together:



Worked a treat on those two 6mm bolts.

The rest of the head & barrel removal went smooth as silk.

Dirty valves, but everything looks okay so far.





You can see evidence that the cam chain tensioner needs replacing; luckily, the chain itself looks no worse for the wear:



Pistons & rings look great, and the bores are mirror smooth (no burrs or scarring of any kind).






Lastly, for this installment, the cam journals all look pretty decent:




Not sure I'll get much else done this week as we're off to San Diego for another kid-related sports tournament!  lol

Cam journals look good. You can see the 'witness marks' are from startup as they are only in the bottom and not full semi-circle,te oil 'floats' the cam away from bearing surface when running. Bore needs 'glaze busting' but looks good. You can do it by and with  some ~300 wetordry'
