1975 BMW R90/6 - Rocinante

Yesterday when I was looking at the battery stay bar I noticed that the rubber O-ring used to hold the side covers in place had broken... and the thing hasn't even been ridden yet! Not cool, you don't want the things to break, ever, but especially not when you're riding; that = side cover gone! I have bought a couple more but decided to just leave them in the bottom of the under-seat tool bin for Road Repairs. I wanted to see if I could come up w/ something better. Broken O-ring/rubber band thingie:

At first I thought about a little piece of chain w/ a small O-ring on each end but that's too close to the battery terminals to use something metallic. I found of length of 1/8" rubber foam core rod that seemed to be an ideal candidate.

Cut to the right length, make loops secured w/ contact cement, stitch & wrap w/ heavy thread, then cover in heat shrink tubing. The first try was a little rough, the next was smoother:

It should be long-lasting because it doesn't have to be stretched very tight to hold them safely in place. The notches in the tabs on the back of the covers are 3mm, very close to 1/8", so the fit is snug.

When the Odyssey battery came in I could see it needed special attention. It's smaller than the original brick and if you mount it toward the back in the normal place that stay bar would have ended up right over the terminals. Again, something metal too close to the terminals probably isn't a good idea. Originally I used a length of aluminum angle but discovered that it stuck up just enough to interfere w/ the bottom of the under seat tool box. I turned it over and it worked that way but required the battery to be tilted forward a little, putting that bright red battery even more in plain sight behind the engine.

This is what I had, not real pretty or graceful but effective:

I had some more of the perforated stuff i used in the bottom of the tray to hold the battery steady so I cut, formed, and drilled to get it into place. I may switch over to a pair of SS wingnuts if I can find some but for now a couple of 10mm nuts do the job.

Looking at many of the other threads on here I truly wish I'd had the time and opportunity in the past to learn machining skills, fabrication, and how to weld and had acquired the required tools to go with those skills, but at this point in my life I'll just cruise on the best I can w/ what I've got and admire other people's work. As long as the ol' girl doesn't fall apart on the road and doesn't look too cobbled I think it'll be ok.

Another afternoon in the shop. I couldn't resist getting the aforementioned SS wingnuts for the battery mount. I should have! Holy crap, nearly $5 each, local hardware price. But they work nice and look good.

At that price, though, I did resist getting a pair for the tank mount! I've seen those offered at the part$ supply places made of brass but guess I'll pass on that, too.

I got the right muffler on and then took the left carburetor back off, again. That carb has just been reluctant to do it's carb thing. In the past I got it to start and run but there'd be a dribble (or flat out flow!) of gas out of the float overflow and if I got the float set so it didn't overflow then it wouldn't run at all on that side. Today I took it all apart again and gave everything an even more thorough and rigorous cleaning, reassembled everything and put in two fresh new spark plugs (I'm not above bribery). It started up and ran very, very well, the best yet... with gas happily pouring out of the overflow. @Hurco550 suggested I try lapping the float needle and seat so I'll give that a go. Of course there are places who'll happily sell me new ones if needs be.

A pix of the right side as it sits at the moment. The mufflers are very quiet and while running there was more mechanical engine noise than exhaust. That's ok; old man bike for sure.

Looking good. I haven't seen where you mentioned the reason for the name. Isn't that a fairly obscure reference to a horse?
 
Yes, that's all back on page one or two. My original thought was to call it Sancho Panzer as a nod to Don Quixote's reluctant "aide" Sancho Panza and to the famed, rock-solid German Panzer Tank. In reflection, the demented old gent's faithful, but worn out, horse came to mind, Rocinante. I guess that translates to plow horse, work horse or even just nag. Fitting? Maybe, maybe not. Others on here thought I was referring to a spacecraft from the book/movie series, The Expanse. I usually don't get all that big into the bike naming thing, but I kinna like this one and even found this graphic, a Picasso from 1955, that I may have a small sticker made either for the top of a pannier or on the tank:

If ya can't have fun w/ things what it's all about, right?

Ha, we're really havin' fun!

Took the left carb float bowl off and fiddled w/ the float/jet relationship: too high, too low, too high, I finally get it so it doesn't dribble out of the overflow and runs enough for the pipe to get warm, not hot. The right side was running fairly nicely w/ just a little help from the left. Not good enough for real riding but I thought I might as well toddle up and down the alley a couple of times just to be able to say I rode it. I got it off the center stand and couldn't back it up! So, tomorrow I hope I can get it back onto the center stand and pull the back wheel to see what's happening w/ the rear brake. One of these days!
 
Rocinante means "no longer a work horse." Also the name of the main protagonist ship in the Expanse book series by James S. A. Corey. The TV series is great.

Yeah I put it into a translator and it came back "nag." Thanx to you folks here I watched The Expanse all winter on the TV in the shop while I was working, yup, pretty good.

I still find it to be an interesting reference to a horse in a 400 year old novel that has not been read by very many people in this century. However, rest assured that I find it to be a wonderful name and very appropriate to this project.

I think Corey might be old enough to have bought a first edition Don Quixote. ;)

Ha ha... yeah if you add their ages together (about 108), maybe! Two guys who write together under one pen name. EDIT: Huh, just looked it up, Miguel DeCervantes presumed born in 1547! He must have written the manuscript on a Commodore 64.

Thank you. Typical for me, when curious I research. Don Quixote is considered to be the first (or one of the first) novel written and back in 2009 was rated highly by a bunch of literary muckety mucks as one of the top novels ever written. It remains popular but probably wouldn't be as popular as it is w/o the production of The Man Of LaMancha on stage and screen. If ol' Miguel had tried to imagine that they would have said he had an Impossible Dream.

It's getting frustrating now. Medical appointment that took much of the day, I finally get back here and could spend some time and we get a visitor! Much of tomorrow will be spent at another medical appointment. Maybe I'll be able to get back at it Wednesday? I think I've finally got the carb set and the rear wheel was no issue so it's ready, and so am I.

I hear you. I have not had 5 mins to get the oil change on the GL or work with Holly on the boat. I am hoping to get to both tonight but we're both fighting a cold so we'll see how we feel after supper. Last night we just went and got ice cream instead of doing any work LOL.

Going to get ice cream is very good for you, sounds like a great decision.
