Title: BMW R90/6.. un-farkle to re-farkle
Post by: Hurco550 on Aug 14, 2017, 20:59:55
I was debating on posting a thread up here, but eh why not. About a month and a half ago I was on the way home from fishing when this 1976 Beemer caught my eye. It was sitting back off the road in a guys driveway with a barely noticeable for sale sign on the back saddlebag. (Perhaps that on top of the fact that the guy never advertised it is the reason he said he had a hard time selling it). The guy who had it was an older gentleman that had been riding airheads since the early 60's, and this was one of 4 he had in his stable, including one really well done /5 with a Volkswagen air cooled lump in it.

Anyways picked this one up for a reasonable price, with nearly 90k miles on the ticker and trimmed in full 70's touring garb. Lufmeister fairing, complete with vetter cyclesound radio (with cassette) wixom hard bags, crash bars with highway pegs, and a luggage rack hanging way out back, with all the glass painted and striped to match.

I had been wanting a vintage airhead for a while. My good riding buddy Al used to put alot of miles on along side me on his r75 and I wanted one ever since.

As i brought it home.

I am not doing anything crazy custom on this bike, but doing a bit of maintenance and losing at least some of the 70's flair (read losing the kind queen and lufmeister fairing). I'd like to put some miles on this thing and have it respectable enough for a vintage bike night or meet up. It has been repainted, and the job wasn't done perfectly, but its better than I can do myself or pay someone else to do, so it will stay, along with the hard bags and crash bars. Luckily for me, the fairing used the factory bmw headlight and turn signals, so it was a fairly straight forward removal and I don't have to spend much $$ on expensive bmw parts. Just pulling it off made the bike so much better looking imho. I also picked up a plexifairing3 for $5 at mid Ohio so I'll have some wind protection without the outdated look and it weighs about a metric ton less to boot. It will need some scratches sanded and polished out, but I can handle that.

 next up is that king queen seat. It's comfy, but it sets me a little far forward, and looks like a dumpster fire, so I'm going to try to make some bracketry to fit a Harley police solo seat. Luckily, I don't think it says Harley on it anywhere, so I should be good ;) my wife doesn't care to ride, so I'm going to ridesolo. See what I did there Cory.. ill also likely make up a nice luggage rack to sit behind the solo seat and above the rear fender to take up that space.

I rebuilt the Bing carburetors as it was only running on one cylinder at idle. I could have gotten away with a clean up and o rings, but I figured I'd better do it right so a couple kits from bing were ordered. Left hand pilot was completely clogged.

All cleaned up and rebuild with a little polishing on the caps.

The top end has to come off as the push rod seals are dried up and cracked. Hit my first snag when removing the right hand side exhaust nut. Every bit of bmw airhead maintenance literature I've read says (usually in bold) to make sure to copper anti seize the exhaust nut. Evidently one of the p.o.'s didn't get the memo. The left hand side came loose no problem, but the right hand side had no such luck.  On kanticoys advice, I just went ahead and cut the nut. The threads will clean up to usable with a little work with a thread file. That probably wouldn't have been the case had I forced it off and I'd likely be looking for a new head. I think ill get by for a while with just a hone to break the glaze and put it back together. I've got 140 cold psi compression on each side.

I see what you did... wonder if I need to copyright the name I've used for somewhere around 30 years.   ;)  Bike is looking good, brother.  It was pretty nice when I rode it, but with some clean-up, tuning, and general attention it'll be a real sweetheart for sure.  That fairing is sort of an issue; it looks great and gives the bike a very specific personality, but it IS heavy and cumbersome and the thing has a much more agile and sporty look w/o it.  You're going to have to find one of these things for me so we can go out and terrorize the cornfields together!  As for the king n queen seat... get rid of that thing fast!

You can bet the front end springs are shot or about to shoot. Mine were progressive....as in progressively getting worse. I had to do them after that first trip up to the Meltdown. Mine had a luftmeister as well.

Pulled the top end apart to do push rod tube seals. Upon some investigation, the top end is a bit of a mod podge of parts from different years. Rockers appear to be 75 model, heads are somewhere between 70 and 74 and the cylinders are unknown, but I'm guessing not original being as they are standard bore with not much wear and 90k miles on the odometer. Probably a swap meet or parts bin special deal, but no worries, it will still work even if not "correct".

Also, the hardly ableson seat came in, and its much wider than I had pictured, but with the extra width from the saddlebags, I think it will do fine. I think minus the bags, it would look totally out of place though.

It is currently just sitting on the bike and I will need to do some fabrication for mounts(https://uploads.tapatalk-cdn.com/20170817/f62f550d56b9a4fce14454a1e0064a38.jpg)(https://uploads.tapatalk-cdn.com/20170817/e2235dc7ccb2b9a716d00dd8a2087fed.jpg)(https://uploads.tapatalk-cdn.com/20170817/72c3a6e7a666f5ac3a15f03e67cfec37.jpg)

The beauty of seats is only when you park it. Gotta have the comfort or you won't go 30 minutes without getting off. If you set it up right you could switch between that and a cool looking flat seat or something. I have an old s seat that would fit that stock tail fine. Just need some paint to match it up.

You could probably get the cover off the seat and trim some of the foam 'hips' off it.  Narrow it down a bit towards the seam without losing any seating area.  Just keep a smooth transition from the top to the sides.

Looking great either way.

Top end put back together with fresh push rod tube seals and gaskets, and the fresh carbs to boot. I didn't do rings at this point as I didn't have the scratch and they were both pushing 145 cold psi per side. If I end up starting to blow smoke, ill do it then, but for now, it'll do. I put er together, clicked the starter and away she went. I'm sure it will need a carb sync, but that will have to wait til tomorrow.

 Time to start syncing the carbs. One known method on airhead bmws is to short out one side then the other using spark plug short rods and a screw driver to the head, until it runs evenly on both. I'm sure this is nothing new to most of you guys, but I figured I'd share my carb sync short out rods. I didn't have the time to wait on a set to order them, and this method is much cheaper. All told I think I have around $7 in the pair. I used two 4 mm by 60 mm long bolts with the heads cut off, two coupler nuts and four standard nuts (all 4mm) as well as a piece of 3/16 inch inside diameter brass tube cut into two equal lengths around 50mm long. All materials  where in the hardware section  of Lowe's. The coupler nut is recessed on the threaded rod enough to screw over the spark plug. I also used two old spark plug thread on terminals. The standard nuts  just act as lock nuts  to keep stuff  from coming apart. These do fit on both Bosch and NGK caps.

Also made up a set of Gatorade bottle vacuum sync gauges. Of course as soon as I went to start it the battery was dead. Oh well, one more thing to chase down lol

 The Gatorade bottles were just a bit too large in volume, so I tried a different route for syncing. I had a set of actual gauges on order, but for the second time this month, for whatever reason, the eBay order got cancelled. Oh well.

Off to harbor freight for a $10 Vacuum gauge (with coupon of course) and a $4 aquarium splitter valve from the big box store. I had to drill out and remove the check valve from the splitter, but other wise it worked well. It would be easier to do with two separate gauges for sure, instead of having to block one off and work back and forth, but oh well, it worked and the job is done I'm pretty sure.

Ha, valves are needed either way to dampen the vacuum pulse, and not buying the second gauge wasn't a $6 issue, it was more that I didn't trust harbor freights Chinese quality control to have a pair of them that were perfectly calibrated to one another

Thanks guys.

And sonic, there is a bunch of debate on that. Some claim that anything with points is safe to do just that. Some claim that you shouldn't pull plug caps on anything post /5. I figured for $7 I would just make up some short rods and not risk it.

You definitely don't want to pull caps with most (if not all) electronic ignitions.

John Deere made a snowmobile back in the day called a spitfire that had a unique to it c.d.i. ignition. If you didn't have the cap on the plug and pulled it over ONE TIME it was fried. Now, there are none of those boxes left, so many of those sleds are sitting around in good shape with a fried box that isn't available anymore.

I did light myself up even with the short rods. I grabbed a file instead of a screw driver the first time and it had a wood handle with a metal sheath up a little farther than I had realized lol live and learn.

Well it felt good to finally have a vintage bike that I felt was dependable enough to do the distinguished genltlemans ride. Round trip was about 180 miles, and the ol lass handled it great. About 70% of those miles were 4 lane interstate traveling at 70+ mph and she didn't skip a beat (though interstate riding isn't gonna be what I continue to do for fun lol)

I am very happy with the old girl so far. Its low on thrills, but is by far the most pleasant, well mannered and refined vintage bike I've ridden or owned to date.

The only issue ive had is the need for fairly constant head re torqueing and valve adjustment after having the top end off. Luckily, there is no easier bike to torque the heads and adjust the valves on. 3 nuts and the cover is off. You don't even have to pull the tank. Its great.

A few shots from the weekend.

Do you mean that you will adjust the valves more than the factory says you have to?

Mine has a 1976 and I would ride it long distance if it didn't have clip-ons and a Cafe seat.  These engines run for ever. 

Glad you had a nice ride :)

I had the top end completely off for push rod tube seals. I have torqued the heads/ adjusted the valves 3 times in the 300ish miles since putting the top end back together. The nuts aren't loose, the studs are just stretching I think

It's very common to strip them, which sounds like what could be going on.  You shouldn't be torquing them this much.

they don't feel stripped. the last torque (while I had it apart to check them) they were almost dead on (only about 3 nm low). I should be good to go at this point. Ill likely pull the covers off after another 1000 miles or so just to check, but all seemed well including the dgr. To be honest, having access to a high end torque wrench probably made me more paranoid than I should. I borrowed my buddies snapon wrench that shows digitally where the torque is when it starts to move and then buzzed, lights up and beeps when you hit the pre set torque. Plus shows the actual torque if you go past

Took the bike down to Barber this year, and Tim hooked me up with an awesome stock seat. Over the king queen set up it made all the difference in the world in my opinion. Fairly comfy to boot.

What do you do when your wife wants limited run candy bars from the Rugrats TV show, and the only place that has them is an hour and a half away? You jump on your BMW and you go get them.

It's funny, less than a week after kanticoy hooked me up with an awesome Wixom trunk, I stopped in at the guy's house that I bought the bike from and he has this one that he forgot to give me when I bought it.

I have to say, I have been pleasantly surprised with this old bike. This is the first vintage machine I've owned that I don't hesitate to jump on it and ride it pretty much wherever. I think she just may be a keeper.

The trusty old airhead ushered my into my first ride of 2018. Sanded the points, squirted a little boom juice down the spark plug hole and away she went. I really do love this old steed.

Ive had it up for sale, and when I got a few calls about it I got pretty bummed, so I pulled the post. There's been times I could have used the money, but in the end, I would rather have the bike than the amount of cash that I can get for it.

I hope its good in the rain. it was about 40 deg. f this morning, so I fired her up and rode to work, then checked the weather when I got here. There is a pretty good chance of her getting a little wet on the ride home. I have my rain gear too though. And I threw all the tools I need to sand the points in the tool box if need be. Irk is hooking me up with one of those fancy points doohickeys to make the points not corrode. Something is definitely amiss, thinking condenser, as I have to sand the points about every time that it sits more than a day.

Can't wait to get Rhonda back on the road - no (legal) road riding allowed here in Quebec until mid March.  Weather's unseasonably warm here right now but the wife says we're in for some cold stuff so all bets are off.

Oh wow, I didn't realize that they had a bike ban in the winter months there.

I hadn't tricked myself into thinking that were out of the cold weather yet. This may just be an indian summer. We've had snow on Easter here before, so were far from out of the woods yet on winter. The only reason I rode today was the fact that we had 3 days of rain to get the salt off the road. We have had warm days before where you could have rode, but the salt is so thick you don't want to spray it all over your machine.

Itís not so much a bike ban as a requirement to have winter tires.

Ah I gotcha. that makes sense.

A friend of a friend claims that he bought winter motorcycle tires that are impregnated with ceramic material for grip on ice.

The idea sounds neat, but I haven't found anywhere that sells what he is claiming that he bought.

Ceramic? Silica is added in the rubber mix for winter tires in arctic conditions. Guess you can call it ceramic.. I would know, i live in that shit climate!

Silica is used in all tire compounds.  It has the amazing ability to give tire rubber low hysteresis at low frequency distortion and high hysteresis at high frequency distortion.  This is why we have tires nowadays with 80k warranties.

There are some with the proper stamp but sized for the big GS rides. Some people have bought them and are still getting pulled over and hassled. They are going to re-word the law to just ban bikes period from what I read. They really don't want bikes on the roads in winter in that province at all.

The old bill hide behind parked cars on my street with speed cameras, doling out speeding tickets to anyone doing 31kph on our 30kph street.  Judging by the look on their faces when they pull someone over you'd think they'd just thwarted the escape attempt of a major felon.

Can't see them being too friendly to a biker in winter, no matter what tires they're on.

Thereís a fellow who uses them over on the quebec m4e forum.

you can still get a ticket for reckless driving if you take it out with snow or ice on the roads, but for a feb day at +5, 6, 7, itís usually not a problem.

As long as the stamp is there.

Youíd think theyíd want lighter vehicles like motorcycles used more often here, easier on the roads. Letís face it, our roads need all the help they can get.

Well now that the bike of the month voting is over, I can post up some pics of the ugly oversized windshield that I just mounted to the bike lol I am hoping to put some real miles on the bike over the summer with a possible trip down to Georgia in the works, so id like to reduce wind fatigue if I can. I picked up this plexifairing3 at Mid-Ohio last year for $5. It big, but looks like it will do a swell job of keeping the wind blocked. It was missing one of the mounting brackets, so I did have to spring $35 for another used set off of feebay. Oh well, still cheap compared to the $250 price new. It has some scratches on it that I need to figure out how to buff out, but ill get there.

I'm also working on installing a "hondaman" transistorized ignition module on it, since I've had some issues with the points corroding. Irk was gracious enough to send me one he had kicking around. Chances are I could throw a new set of points on and a condenser and fix the problem, but these units claim to make the points last almost "forever", so as Forrest Gump would say its "just one less thing".

They seem to be pretty well known for being ugly but doing a wonderful job of what they're supposed to do.

I did another oil change, even though I had done one when I got it, but I figured now is as good a time as any so that I can pile on the miles this summer. I had neglected to do a transmission oil change though "I know, tisk tisk.... I opened up the drain plug to a very un welcomed sight, milky white oil. It's good to have a network of motorcycle minded friends though, and a few beemer gurus at that. It didn't really make sense to me how moisture would enter the system, until kanticoy pointed out that the tach cable boot was known to fail, allowing water to run straight down the cable and into the trans. That's exactly what the issue was I believe, especially considering I don't know how long it's been since the last trans oil change, and it rode home 10+ hours in the back of a truck from barber in a hurricane.  He also pointed me in the direction of an "improved boot" that is available, so one is on order.

The driveshaft and final drive also got a fresh helping of oil, so she should be good to go.
