Just bought a R/80 at estate auction
Just bought a R/80 at estate auction
I’ll be looking for advice on parts and common issues to be aware of when resurrecting. I’ll go through the fuel and ignition and change all fluids and get it fired up. Then brakes and tires. I’ve got experience with vintage Italian car restoration, but a German bike is completely new to me.
Re: Just bought a R/80 at estate auction
I resurrected a R100 in about the same condition last year. Had to evict the mouse family from the top of the air filter.

Re: Just bought a R/80 at estate auction
You may get lucky and just have to do some minor stuff to get it road worthy. Tires most likely will be shot from age, I wouldn't trust them. Oil change and gear oil change, look for water in fluids, there is the main engine oil, transmission, drive shaft and final drive.
The master cylinder is under the gas tank and old fluid there being water loving could have caused the worst damage.
Any signs of critter invasion? mice love to climb into the mufflers and store seeds, they also like the air cleaner. LOL, I have seen some big internal messes when the air cleaner is opened up and the mouse house is revealed.
As for year, it is most likely after 77, a 78 and newer as 77 bikes were 750cc, a one year only model, the R75/7.
Anyway, keep us posted on the rebuild, good luck, there are a lot of online resources now that didn't exist ten years ago. St

I’ll inspect the wheels, air box, etc.
The gas tank does have the original orange/red lining.
If replacement recall wheels are not available, does the dealer offer others or will I have to purchase aftermarket on my own?

So likely all you can look to do is find an aftermarket wheel. The original /7 series came with spokes...not sure if the later bikes can be refitted. Lester wheels were a popular aftermarket option back in the day.

Re: Just bought a R/80 at estate auction
Used wheels are out there, but like anything it is a gamble on buying a used one.
There was a podcast online look for BMW 247 podcast. One of the fellows covered in detail the wheel recall. While I won't start a discussion here, it might be fine to just keep the wheel you got. Hey, I am not an expert, I just listened to one discuss the issue and drew conclusions.
Regardless, the podcasts are very interesting. Good luck, St.

Re: Just bought a R/80 at estate auction
Well I finally got to spend some time with the bike and here's what I found so far:
VIN 6126144
Emissions tag on rear fender says 1980
Front brake master is seized up.
Engine oil is clean, gas tank is bone dry and no rust.
Front wheel is original 19 in. Snowflake without any hairline cracks.
Sparks plugs black with carbon.
Hooked up a jump pack and all lights, horn and dash lights work,
With new spark plugs out and resting on the head, engine turns freely with the
starter and has good spark.
Pulled the air box and found mouse nest.
Removed the master cylinder.
Next steps, buy a battery, change the motor oil and drive shaft oil, pull the carb bowls and inspect.
Rebuild the master cylinder and start it up.
Advise on rebuilding the master? A quick Google and the prices are high for a new/rebuilt one.
From what I see so far, it appears the previous owner prepped the bike for (winter?) storage. Drained the tank and changed the oil. So far I'm very pleased with the bike. Its dirty but all intact.
