    G'day.

    After lurking in the shadows for the last year or three, the time has come for me to state my rank and purpose for being here. I'll try to keep it succinct, but have my doubts as to being successful in that regard.

    Me - just a bloke that has never ridden a street bike, but has wanted one since he almost bought a basket case (literally) BMW [sumthin]/[sumthin] in the late 1970s as a teenager. Mom said no, so that dream got put off. I Married an ER nurse in 1987 and we have two boys 16 and 18 as of this writing. ER nurse as spouse = adamant refusal to accept two wheeled transportation device (more on that later). We live in an old (~195 y.o.) farmhouse in northeastern PA. An engineer of sorts by day; otherwise a restorer of sorts of old houses, cars, trucks, and now a bike. We like to play and camp off the beaten path in our Jeep(s).

    My bike - this is where the story (if you have not died of boredom or clicked away already) might get interesting. No promises.

    1979 BMW R100T. Yep, plain jane, red/silver, nearly 100% stock and original. This bike I have known for about 8-10 years, as it was owned by a good friend that I work with. About 4 years ago he had some engine issues with the bike, and attempted repairs. He was less than successful, and parked the bike in his shed. He bought a 1984 R100RT to ride while he fixed the '79. Never happened. He offered me the bike in as-is condition, so I of course accepted. :deal Idiot. :eek1

    Below are the pics of the bike as I acquired it. I will post additional entries and pictures in this thread as work progresses. I may struggle with the picture links, but please be patient.

    As found in the "shed". It was actually a tent structure with the tent rapidly departing the premises.

    On the trip home. About 70 miles, with a borrowed trailer being pulled by my '05 Rubicon LJ.

    And here it is at home in my driveway. That is a Windjammer faring on it. I did also get the Krauser bags and keys for everything with it.

    Next post will have some more info on the bike and some nasty pictures.

    First off, I would suggest joining the Airhead Beemer Club. Best investment I ever made. Great bunch of folks and knowledge about these old bikes that is priceless.

    Secondly, They will be having a Airhead Tech Day in Pocono Summit on April 30th.

    I sure there will be enough talent there to steer you in the right direction as to what needs to be done to your bike.

    PM me for further details if you are interested.

    Take care,

    Dave

    So after getting it home and out of the trailer, I had to pull off the faring. I mean no disrespect to all the RT owners out there, but I really prefer the "naked" look of the early airheads. Here it is in the garage with the Windjammer-ectomy performed:

    [​IMG]

    The next phase was to remove the airbox to see what kind of presents the rodents left in there. You should be able to guess how I came up with the nickname for this bike:

    Eeeew. S'more:

    And from the front:

    Sorry for the poor resolution. These are cell phone pics. Hope to be getting a good digital camera in the next week or so.

    Next post will have more background on the engine issues, past and present.

    Great welcome thread from you. I love the look of the Windjammer fairings. Looks like you have some work ahead of you with this one. I would get her running and leave it that.

    Yep, rodents will do that. Did you luck out and did they miss the carbs?

    You'll be getting some good advice on all what to check, mainly a LOT of little fiddly things.

    Yes, consider the ABC (they have a great local organization) and please, please, do take an MSF (Motorcycle Safety Foundation) training course. There are few things more dangerous than an old guy on a new second-childhood bike... (there, been looking for an excuse ot say that).

    FWIW, here is my Photo site with my R60 pics:

    Bill - thanks for the institutional welcome :lol3. I loved the picture of Mom on the H-D. She reminds me of my Grandmother (93 and still going) who used to drive tow trucks as a part time job at a car dealership when she was in her late teens (this would have been in the early 1930s). Tough old birds those early 20th century ladies . . .

    Luckily the mice did not get past the air filter, so the carbs are remarkably clean. I am getting a gasket and o-ring kit for them just to be sure they are good to run.

    I :roflat the second-childhood comment. You been talking to my wife? :D Seriously though, I have every intention of taking a safety course. I have ridden dirt bikes on trails many times since I was a kid, just never a street bike. I have road raced sedans since I was 17 all over the northeastern US, but dropped that a few years ago. The race cars were a lot safer than riding on the street :eek1.

    So after several heavy rounds with the shop vac, I removed all of the loose maus nesting materials I could from the engine. I noticed shiny where there should be no shiny, specifically in the middle of the primary alternator wires. :cry

    [​IMG]

    Amazingly, they only ate the insulation, but did not manage to cut any of the wire strands.

    [​IMG]

    I was able to slip some heat shrink tubing over the primary wires and get them covered up again. I have similar issues with a few other wires still to address.

    I did connect a battery to the terminals and put power to the harness. No smoke fell out of anywhere, and she actually cranked over without too much complaint.

    The mice also made the headlight bucket their penthouse. I vacuumed tons of poop out of there as well. The headlight harness was hacked to splice in the Windjammer harness, so I have ordered a new one. Other than that, I was able to trace out everthing and get the headlight back in the bucket.

    BTW - I do have a Clymer and Haynes manual for the bike. So far they seem pretty good guides when I need to refer to them.

    I've been riding forever and a day, and the "MSF course" advice, and sometimes the "old guy on a bike" joke, is SOP. Especially during the past few years, I've seen a lot come to grief by going too much too soon.

    Parts source? I dunno-- my experience is with my Classic, and not a new-fangled 1979 model. Others can advise. Support you local dealer if you can, but sometimes "alternate suppliers" are a necessity.

    Parts book? With the Internet, you are in luck. There are online "parts fiches" which will give drawings and part numbers. I like MaxBMW:

    http://www.maxbmwmotorcycles.com/fiche/fiche.aspx

    this is the "select your model" index page. Go through the selection process, and then Bookmark the page for your model.

    Chewed wire? It happens. You can patch and everything, and (at least for the older bikes) a new main harness isn't that bad in $$.

    Oh, reminds me-- check with ADV inmate wirewrkr -- he does wiring harnesses. http://www.wirewerkes.com/

    Airhead electrics? Rick Jones at Motorrad Elektrik http://www.motoelekt.com/

    'Nuff for now-- got to get ready for a ride tomorrow.

    I did not want to impart my opinion, but I'm really glad you ditched the fairing, man I hate those Windjammers! Have fun!

    Sheesh! 46 years old makes me an old man? My brain is only 26! :huh

    Thanks for the link. That will help with some of the more esoteric stuff I will wind up needing/wanting.

    I alredy ordered and received a new headlight harness from Wirewrkr via BMWEuro's shop. Looks like a nice piece.

    Jeff Trapp (northwoodsairheads) put me onto Rick's stuff. Specifically his hard mounts for the rectifier. I may build my own just for fun, but he has nice stuff too. It is wonderful to have all these options for the airheads.

    Thanks, and enjoy!

    'Twas a good ride, though windy.

    Like they say, growing old is mandatory but growing up is optional.

    You're off to a good start, you've done your homework. Jeff Trapp has parts and a good selection of special tools. I'm getting ready to order an Exhaust Nut Wrench from him, my old timey cast-iron one is too thick to fit the exhaust nuts when crash bars are fitted and I'm getting tired of loosening the bars when I do my periodic "put anti-sieze on the exhaust nuts maintenance".

    Oh, beg borrow or steal an exhaust wrench, you'll need to check yours. If they are tight (and possibly siezed), holler back before wringing them off-- the fix can be from mild to wild.

    If/when you need speedo work, Inmate Wirespokes does speedos and tachs.

    Off to do yardwork. Never ends... :evil

    Nice looking bike you've got there! I like that color scheme. And the 100T is a good model - essentially an S or RS without the fairing.

    Good for you removing that windjammer! She looks much happier already!

    What's the story on the original trouble that parked her?

    After a bike sits that long you'll need to sort through everything. Cable ends will need lubed or they'll break, the brake calipers and master cylinder will most likely need to be dismantled and cleaned at a minimum, and who knows what seals will fail. And I'd suggest hitting all of the electrical connections making them bright and shiny. As for the seals, just replace as they start leaking - some will be fine.

    Good advice on the exhaust wrench. That should be a standard tool kit item.

    Before starting her up the first time, rotate the rear wheel for five minutes or so to get oil splashing everywhere, especially the transmission bearings. And then when you fire her up, let her run in gear, on the center stand, for five minutes for the same reason.

    If the speedo is jumpy, lube the cable. If that doesn't fix, the speedo will need a cleaning/lube. You don't want to take a chance wrecking the little shafts and bushings in there since they're no longer available.

    I've got an 80 R100T with an RS fairing I rode all over the west coast for five years. They're wonderful bikes!

    Spit and polish? I'm on pins and needles wondering what the PO meant by "some engine issues with the bike" and of course what the "attempted repairs" were.

    At least Jim knows his way around machinery, so I'm looking forward to the rest of the story.:deal
