Another question, should the wheel spokes be replaced?  They generally don't look too bad, some rust on the nipples and a little oxidation.  I was thinking of taking the wheels apart to properly clean and polish the drums and wondered if it was the right thing to do to replace the spokes.

They look in pretty good shape in the pics and look like they would clean up pretty well. Stainless spokes can be fairly pricey but there should be lots of aftermarket options available on eBay etc for cheaper. I have had mixed results with eBay spokes, the ones I put on my XL350 barely fit and started corroding about 6 months after I installed them (before any riding). The eBay set I put on the 360 were better quality.

Thanks advCo.  No worries about metal fatigue with these old spokes?  I'd definitely rather keep the originals and just clean them up, but don't want a wheel coming apart!

The spokes on my CB750 were in pretty rough shape - way worse than yours.  I decided to restore them rather than buy new sets, bit of a lengthy job but they came out looking good and after a year or so still do.  There's factory plating on them (they're not stainless) which you may end up stripping.  I made a fairly ghetto rig by clamping a dremel into a bench clamp, sticking the spoke in the dremel and used wire wool to clean them up.  Once I got the oxidization/rust off then I clearcoated them with some 2K clear I had left over from my gas tank.  Job's a good'un.  I can link you to the thread if you like which shows a couple of photos of what I did.

As far as I know metal fatigue is not a huge concern, unless of course they're totally rusted out.  I even had a few bent spokes too, which I straightened out.

The spokes should continue to be strong enough.  The only thing to watch is that if you wire wheel them, it tends to strip off all the zinc or cad plating and after that they rust. What I do is remove them and clean them up and get them re-plated and heat treated, but that's almost as expensive as just replacing them.

Zinc is better on spokes than chrome, though I have done both.  In either case, they must be baked after plating to remove the hydrogen which causes them to become brittle. The plating shop can do that for you if you go that way.

I have also just spray painted spokes and that looks OK and works fine too.

Headed to the auto junk yard tomorrow with my boys to hopefully find a donor bike...

Engine parts needed:
starter
clutch
clutch cover/right crank case cover
oil pump
oil filter and cover
generator rotor
generator stator and left crank case cover
starting motor sprocket, starting sprocket set plate, starting sprocket
exhaust flanges
oil drain plug

Depending on what I find I'll also look for another front and rear fenders, carbs, etc.

Does anyone know if there is an issue with using the K1  style breather cover/plate on a K7?  I know the older models had the breather on the intake side, and the newer models had it on the exhaust side.

The vent is busted in the one I have from the K7 engine (bottom in the pic), but I happened to have one from a K1 model (top). The only difference I see is the plate design and that the old style has two breather holes instead of one. Looks to me like I could use the older (nicer) cover with the newer plate and install it on the exhaust side.

Is this pitting something to be worried about, or dealt with?

I wouldn't get to worked up about that pitting personally as long as everything else looks kosher, bearings ect
