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?

and that is why you don't see many MC's inside the beltway.  I try to stay out of that area.  heck, i went on a three day ride in the boonies of WV last week.  rather than risk the DC beltway traffic and summer heat, i trailered the bikes out to winchester and rode out from there.

Put in the new clutch and accelerator cable adjusters. Fitted the airbox into the new air intake boots. Adjusted the clutch and the level, still need to adjust at clutch point. Also still.need to grease accel gears in lever.

Registered the bike! Also made a lincense plate bracket, figured out why the fan wasn't working (load shed relay missing). Tried adjusting the clutch cable but I'm afraid the clutch is slipping. Taking it apart today.

So.... Previous owner did say he replaced the clutch and he did. Just with the friction disc backwards..... Lucky there was hardly any damage, the spring diaphragm had a small indent from where the friction disc boss was rubbing against it. Also turns out I had two ignition wires on the wrong plug... Wow, that really woke the bike up.

my new valve shims arrived mid week.
2 of my inlet clearances were tight 0.09mm and 0.11mm (min is 0.15mm)
i had to install shims measuring 2.45mm and 2.5mm to bring back into spec.

i purchased these shims from https://www.tills.de

they supply 29mm diameter shims down to a thickness of 2mm, so plenty of adjustment left for now


i had previously purchased the valve adjustment tools from Ken Lively, polepenhollow@yahoo.com

even so ,it took me an hour and a half to extract the first old shim,

i had a set of fine picks that i was using to try and coax the old shim out with but even so it turned into a battle of patience and persistence on my behalf versus that silent mechanical German goading that i am becoming accustomed to.
eventually it did pop out to my relief. an hour and a half!!!!!  yawl

next time i will pre purchase a telescopic adjustable magnet.
 i have seen a video where you can blow them out with compressed air , which seemed to work brilliantly.

in contrast , extracting and replacing the 2nd shim took 5 mins.

I also installed new spark plugs.

I let the smear of gasket sealant set overnight on the half moon rubbers and the front corners near the timing chain.

took it out for a ride today and it is running noticeably better (i actually thought it was running great before i had done anything)

so whether thats due to the new plugs or the valve adjustment or a combination of both I will never know.

next on my list is a throttle body balance

haha, back in the 70's I used to covertly switch 2 plug wires on my brother's 63 beetle.  It would run but barely, then I'd charge him $5 to fix it. He thought I was a genius.

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.

Yes, Gryph, awesome paint job!  It looks like a SE model on steroids.  I love the colour combination and the RS lines.

Thanks Rob for the kind words.  Hope to take a maiden shakedown ride on Monday.  Not too far, just into town to get some fresh fuel in the tank and pick up the K100RS graphics for the belly pan. 

Buffing pads and compound ordered.    Hope to commence buffing festivities next weekend.

I think it's gonna look okay.

Rode out to the TonUp club meeting. Refurbing the intake and injectors really smoothed things out. No more hunting at steady low rpm, no more dying when coming to a stop.
85 mph on the interstate, and it begs for more.

That's genius. I knew something wasn't right, although I've never driven a brick before so i didn't know it was missing that much power. I made a bracket for the aftermarket speedo the PO put on and rode it probably 50 miles today. I absolutely love this bike.

Hey, Blitz!  Good to hear you finally have it running.  Was it the return line plumbing?  Hope you can now replace your travails now with travels.

Zenitramnaes, you weren't the first to be fooled by the #4  plug wire being longer than the #3, and you probably won't be the last.  Good to hear it's running so well now.

I did over 2000 miles this summer for the K. My Airhead only got about 300...K convenience, ease of starting/warmup. It is so less needy.

I tightened up the headlight assembly by using some over-sized washers between the existing washer and the central pin, stopped the headlight assembly from shaking so much.

After I was finished I adjusted the headlight using the method from the owners manual. I know, I know, bike is on center stand, it's daylight, moon is wrong phase, etc. etc. but I don't ride much at night any more (53 years young) and I just wanted to make sure I wasn't blinding my riding partners.

Crossed off a couple of items on the list and went for a quick ride up Route 579 from Ringoes NJ to Pittstown NJ, great motorcycle riding road.

The more I dig into this 56K brick that I rescued off Cape Cod, the more I like it. Gearbox and final drive oil look new, bolts I remove have anti-seize on them, air filter was new, etc. Looks like it was cared for and maintained, just not ridden by the last owner.

Have a great Labor Day weekend (if you're in the US) and let's welcome the fall riding season, cheers!
