After 20 minutes of riding:
Drained rear drive oil.
250ml NAPA 80w-90 added to rear drive.

Drained crankcase oil.
3.5 liters 20w-50 BMW mineral oil and BMW oil filter to crankcase. Used a cap filter wrench on a 3/8 drive extension and ratchet to remove and install filter. Replaced filter plate o-ring after using the previous one for four oil changes. All screw washers were reused. I've been reusing them after oil changes for the last three years. Certain members here want to know what they look like. They're circular. They fit the screws as though they were made for them. They aren't paper thin but neither are they thick. Their colors comprise an arc of hues from burnt sienna to burnished slate. Color matching isn't a high priority for me.

Drained fork oil from sliders at rear drain holes.
410ml 7.5w fork oil added to both fork tubes.

Checked torque settings of fork brace bolts—top and bottom.
Checked torque setting on rear shock fasteners.
Checked crankcase ventilation z-tube because Blackie checked his. Tube is ok. Expecting peace of mind anyway. :giggles

this is ambiguous, were all of them not replaced or were some of them but not all of them?  If so why? And are those lock washers or regular washers?  I want to try this sometime and really need to know.

But does BMW recommend screwing the same nut twice or more times?

They leave it up to the degree of loneliness being experienced by the screwer.

Installed new battery and made battery tie down bracket, rewired fuel pump connector, rewired brake light connect, cleaned and connected front brake lines, fitted back some original levers and switches. Waiting on new handle bars and just ordered a new clutch cable and all the rubber between the throttle bodies and intake.

checked the valve clearances today
one and three intakes were tight , the rest were in spec.
awaiting a couple of shims which i ordered today.

check out the half moon rubbers on the right hand edge.
 
that light brown/ yellow stripe across them is a very precise strip of sealant / rubber compound.

do you guys think that would be from the factory?
 it was really the only bit of sealant to be found anywhere on the gasket.

do you think that this may be an indication that i am the first person to ever remove the the cylinder head cover.

my machine is a 1991 k75 with about 47,000km on the clock

It could be that, or it could be that whoever performed maintenance on it last worked with precision, eg., a BMW dealership tech performing a scheduled valve clearance check early in the moto's life when the owner might actually have cared or had the money to have it done, or an owner accustomed to working with precision.

Got the brake lights all wired up correctly. Cleaned out the ignition switch and got that working correctly. Cleaned up the solder joints in the left control switch, light wasnt staying on, fixed. Headlight wired in. Fuel hose in tank came lose, reinstalled and tightened. Drove the bike around in the shop parking lot, slowly getting there!

Did some painting on parts for my 1991 k100rs.  Doing a bit of a tribute to the K100RS special edition paint job.  So far, I'm pretty pleased with the results.

Cut the stock front mud guard a little shorter and bolted it in. Checked all the torque on all the bolts regarding wheels and triple tree, PO left some a little loose. Installed the DME cover box in the bike. Tighten my exhaust clamps, checked that the alternator is charging. Should be ready to ride this weekend hopefully.

New brake lines are made and in. New clutch cable in although looks like I'm missing the adjustment screw at the levers. Took apart the throttle bodies in order to clean up and install new intake boots, fuel lines, and vacuum hoses.

MG: that is a superb paint job. Is there a slight tint of blue, possibly metal flake in the stripes?

This morning the K75s got some boring highway miles to D.C. and then the fun started. I've driven all over the world, including Cairo, Napoli, and SF ... D.C. is the absolute scariest place on two-wheels, bar none! Came in from the south, and went to Georgetown, had 2 close-merging cars push me and thought "gotta be a fluke", then almost got sandwiched on the Key Bridge which gave me some serious religion squirting out of that one. Only saw 3 other riders today in the city, 2 were on newer R's. Anyhoo, whose the patron Saint of motorcycles?

Thank you!  The blue is Ford code DX Dark Blue Metallic.  It has a metallic pearl in it that is only visible in strong sunlight.  The stripes were masked with 3M pinstriping tape to imitate the official BMW stripes and painted with the body paint.

The white is Ford code UG Platinum White Tri Coat.  First time I ever did tri coat; it's way easier than I thought.  Shot the color coats with my trusty(and cheap) Badger 250 air brush.  Takes a bit longer to get the paint on, but it's impossible for me to f-up the paint with it.  Clear is a 2K clear in rattle cans.  I can't believe how nice the spray pattern was and how easy it was to lay down.

I shot everything in my home made spray booth.  Tomorrow I hope to get the main part of the fairing and the belly pan painted so I can do the assembly over the weekend.  With any luck, I'll have some piccies of the finished bike on Monday.

Everybody does that chit.  I'm gonna chop off the steering head.  It's gonna be rad, but with no forks I'm trying to figure out another way to attach the strap-ons.

fixed a crack in the bottom of my city saddlebag with some flat stock and jb weld.  It's was on the bottom so it doesn't show.  I like the little bags, makes me look skinnier while riding.

Finished painting over the weekend and got the bodywork put together on Monday.  Still need to block sand the clear and buff it out, but for now he looks good enough to ride.
