Marian Call came to Minneapolis this weekend for two concerts and Liz and I went to both!
I shot a handful of photos at both concerts.
Here are the photos from the Nicollet Coffee House concert.

I noticed the other day that the headlight lens on the R100RS was smoky on the inside. It looks like maybe a bulb blew up at some point. I’m a firm believer that you can’t have too much light on a motorcycle at night, so I need to clean it.
I have a Porter-Cable Model 444 profile sander. I’m not sure where I got it, and I’m not sure I’ve ever used it. I think I either bought it used, or got it from my father.
In any case, I wanted to use it the other day. I got it out, put some sand paper on it and got to work. Suddenly it started making a different noise and shaking really badly.
The head was really loose and shook from side to side. That’s not right.
So what do I do next? I take it apart to investigate.
Since the 528i is a BMW, it’s a little overly complicated. Because it’s German. Why make it simple when you can make it complicated?
The headlights on the 528i have a auto-leveling feature. Which means that if you load the trunk full of stuff, thus lowering the rear and raising the front, the auto-leveling headlights will compensate and you won’t blind on-coming traffic.
Which is cool, I guess, but it also adds more stuff to break. And break it does.
When I was polishing the headlights I heard some rattling in the right one. So I opened it up and took out some chunks of white plastic. Since I’ve spent some time surfing the various BMW forums, I knew what that meant.
About 6 weeks ago we bought a 1999 BMW 528i wagon. I really love this car. But since it’s 15 years old it has some issues. Nothing major and I’m working my way through them.
One of the issues is that the headlights have plastic lenses (as do most cars starting about 20 years back) and they are fogged and pitted. They are not too yellow, but they were pretty foggy.
Yesterday I got mad enough to really figure out why the rear brakes were not working.
I ended up taking off the master cylinder to adjust the linkage (it’s really a pain to adjust – you either have to fully remove the master cylinder and brake pedal, or remove the rear wheel and the swingarm!)
I also took the caliper apart again to make sure the o-ring was seated correctly (it was) and not pinched (it wasn’t.)
Then, as I was trying to bleed the brakes again, it struck me: The way the caliper is mounted means that the pistons are higher than the inlet and the bleeder valve. There is no way the air is going to come out of there!
So I unmounted the caliper, again, turned it around, and slipped it back onto the disk so that the bleeder valve was the highest point. Then I bled the brakes and what do you know? I got a bunch of air out and it firmed right up! Damn it, that took way too much mucking about to figure out.
So that was the final hurdle to finishing up.
Today I did a rough balance of the carbs and then rode the bike around for a while to get it fully warmed up. Then back into the garage to adjust the idle, idle mixture and balance.
It’s running pretty sweet now! I stopped in a parking lot and shot a short video of it idling.
I’ll have to get one of it starting for Jon – it still starts nice and quick.
If it’s not raining in the morning I’ll be riding it to work!
The reason the title of this post says “For Now” is because there are still some issues to address:
Still, all in all, it’s a fun ride, the exhaust sounds great and it will do 80 MPH without too much drama, though it seems to prefer 65-70. (I happen to know it was capable of more than 100 MPH in the past, but I don’t think I’ll be doing that again any time soon.)
It struck me the other day that I have had this Luftmeister two into one exhaust on the bike for more than 15 years and have never repacked the muffler.
I decided I’d better open it up and take a look.
The first step was to drill out the pop rivet and pull the baffle out. I grabbed a punch and drove the expander pin through the rivet and into the muffler, then I chucked up a 3/16″ drill bit and drilled the head off.
A whack or two with a larger punch and the rivet body fell into the muffler.
I ended up taking a large screw driver blade and prying the end cap off, probably not the best plan, but the finish is kind of ratty already and I didn’t damage it much more.
I pulled out the baffle and was surprised to see there was still some packing in there. Not much, but some anyway.
Now that I had some idea what I needed for packing, I had to go find some on the internet. Surprisingly, Amazon had some. I ordered two packages and ended up using almost all of it.
I had to run to the hardware store for some 18 gauge wire to tie up the fiberglass. Someone (my daughter) borrowed my spool and didn’t return it.
That fiberglass is nasty stuff to work with. It’s really friable and gets really small fibers everywhere. But I managed to get the baffle wrapped pretty well.
Next I had to get the baffle back into the pipe. It was a tighter fit with the new packing on it, but I persuaded it with a wood block and a mallet.
A new stainless steel pop rivet (also ordered on Amazon) and it’s all good to bolt back on.
I should probably wash the muffler while it’s off the bike and I’m waiting for some more parts…
Should be all good to ride soon though!
I got on the K1100RS to ride home from work this afternoon and headed down the road to get on the freeway.
As I accelerated down the entrance ramp all of a sudden the tach dropped to zero and the engine started running really rough – like it dropped a cylinder or something.
So I pulled over on the shoulder (good thing there was a shoulder) and shut off the bike. Maybe a restart will clear it up.
Nope, still runs like shit with no tach reading. Weird.
I put on the flashers and babied it along the shoulder to the next exit. Right when I got to the stop light at the end of the ramp the tach sprang to life and the bike started running fine!
So I got back on the freeway and the bike ran fine all the way home!
The intermittent failure mode and the tach behaviour rules out mechanical failure, so there must be some electrical issue. Great. Those are always fun to troubleshoot.
Preliminary googling doesn’t turn up much other than “clean all the electrical connectors” and “might be a bad computer” (Ye Gods I hope not!)
I guess the K bike is getting jealous of all the attention that I’m paying to the R bike these days.
And I just bought a BMW car why?
The seat hinges arrived today so I could attach the seat to the motorcycle. So in celebration I went for a short ride!
I actually went for two rides.
I started the bike and did a rudimentary carb balancing and idle set, just so it would run well enough to give it a warm up ride. Then I rode it around the neighborhood for a bit. It was running pretty rough just off idle, but surprisingly well in the midrange. And I only killed it once.
After that, I hooked up the balance gauges and adjusted it a bit better. I got it pretty balanced, but the new throttle cables need to stretch out a bit.
It’s running really lean because of the Luftmeister two into one exhaust and K&N filter, so it spits and pops at idle and under partial throttle. I’ll have to get some richer jets for it.
Then I took it out on the freeway for a few miles out and back.
It pulls strong from the midrange on up, but it’s probably still lean there too. I didn’t want to go too far with it so lean and with no rear brake (who needs rear brakes anyway?)
I also got a nice reminder of why they call these “Gummikuhs” (rubber cows). It feels pretty flexy even compared to my K1100RS (not the stiffest of frames either.) I’ll have to make sure the swingarm bearing pivots are tight enough and that the steering head bearings are adjusted properly.
So, still plenty to do to finish it up, but it’s running and rolling now!
Since the last update I’ve done the following:
