I wanted to say hello to everone and give a big Thank You to all the fellas that advised me this last fall!

I drained the tranny fluid before purchase and the magnet had fuzz and a few...I'll call them flakes. No 3D chunks of metal.
I ended up buying the bike in question! A 1984 R100.
Rode it home and swapped tranny fluid again. Checked all other fluids and took it for a good half hour ride. Put it on the stand when I got home and dropped all the hot fluids. Engine, tranny, driveline and rear end. Filled them back up and hauled ass for the next 6 weeks. Man...I love this bike!

It's back on the stand now with the tranny out. It's getting a new clutch and the input shaft splines greased. The splines look good by the way.

Cheers Gents! I hope to be around here quite a bit!

Congratulations!

"Flakes" are not something you want to see, so keep a close eye and ear on that tranny. You would be well advised to start looking for a good replacement now, as the tranny is generally considered the weakest link in the bike. If it doesn't fail now, it probably will eventually, and, even if it doesn't, that backup tranny will always be worth at least what you paid for it.

I'm a man of wealth and taste


(sorry, could not resist ...)

Nice bike, glad you got some good miles.
I just wanted to mention that I go along with the good Major, the transmissions I have seen that had a complete bearing failure were damaged throughout. New bearings will get them back on the road, but they are never the same. The hard metal fragments try to cut themselves into everything.

Roger that on the keeping an eye out for a tranny. This last time I dropped the fluid there was fuzz on the magnet. I haven't found flakes other than the first time I changed it. When they go out do you generaly get to finish your trip home or do they just go clunk and stop.

Vanzen, I had hoped the next line would come up!

They can soldier on for some time with bad bearings, but with the metal in supension, much damage is being done. That is why it is good to catch them early.
I am not an expert, but from what I've seen the front output shaft bearing is usually the first to go. After the cage is eaten, the balls go off center throwing the shaft off center and things start to bind and break. That is when the party is over.

Welcome as the newest resident here in "the home."

If you ask a question for which we don't know the answer, don't fret, we will give you an answer with great confidence anyway.

The photos show that I have a buck in my pocket from some previous owner of the bike. I refer to the backrest.

I have seen them go a few thousand miles easily on a transmission showing flakes. If you have a known good one as a spare, that is the time to install it. Even the first time you can do it in an afternoon.

You must answer a basic question, why do you have it? Is it to ride, or mostly as a project to fondle and cherish and sometimes ride?

Consider getting rid of those crashbars. They are dangerous. Google the subject.

Almost anything that you could want to know is already documented well on the Internet. Google is your best friend. Some people that have a keyboard feel that they are experts, but aren't. Of course we don't have such ilk here on boxerworks. Often you can get the info needed faster off of the Internet than here. We strive to offer up contradictory advise and degrade the thread to total chaos.

Then there is Diane.

Did you start a logbook on the bike? Record everything you touch, find, fix or think needs attention. Write down what you got for history from the PO. You may want to keep it in an excel file, or on the computer.

You are on the right track by checking things often, such as this transmission.

Did you check the charge voltage? Have you checked the flow rate from the petcocks? How about lubing the wheel bearings and swing arms? Do you have fork stiction? You can keep busy with diagnostics that could well find something amiss now.

If something seems that it needs to be forced, stop and ask here first. We are saddened by folks that come by and have owned other bikes and applied that wrenching to the BMW. We see folks have to spend ten times more due to not asking first. Don't make well known mistakes. Don't reinvent the wheel.

Yes, it's much more interesting to discover new, heretofore unknown, mistakes. They will make your posts much more exciting for us all.

LOL, On purpose, I didn't eleborate.

Oprah specializes in "new" mistakes. Mostly we make old mistakes and just waste a lot of time and $$.
