G'day all,
I have just bought a basket case K 100 RS for the grand sum of $250 . The plan is to rebuild it over the next year or seven . All my previous bikes were Kawasakis , so I thought I would try something very different from what I am used to.

Hello Plowy. Yep they are different. But in a better way. I'm biased however!

Where in Qld?

Hi Ya plowy welcome to the forum. My last Jap bike was a Kawasaki which I still own but I can't see myself going back to it as a fulltime ride. These Ks are very addictive. You will end up with a bad case of Kpox. BTW where in Qld it's one big place care to narrow it down a bit.

"BTW where in Qld it's one big place care to narrow it down a bit."

Is there an echo in here?

Echo Echo Echo Echo Echo Echo Echo Echo Echo Echo Echo.


BTW. Welcome to the madhouse, Plowy.

gday mate...boy do you have an adventure in store.....you will be able to find any part you wish thanks to the gents here who know everything and very clever with it....I have had new bikes where parts were harder to get ...yep Kawasaki....so enjoy mate I wish I had found this earlier..the K100RS and the forum...

watch out roaches, the toads are gathering in force.
welcome onboard Plowy, you should enjoy.

By the way "GO THE MIGHTY BLUES"

Um, that's a reference to some sort of football game isn't it? Yawn...

It's what you get when your team doesn't win.

I currently live in Townsville but am originally from Sydney. I am currently going over the bike to see what is working and what isn't. The bike sat for at least six years, so it is in a very rough condition.

Whew 6 years it just might need a bit more than the usual TLC but for $250 if it's all there you are off to a good start.

Ok. Then you'll may want to know where you get parts from?

Motobins, based in the UK. Takes a couple of weeks for stuff to arrive to me.

Motorworks, also UK based.

James Sherlock, as above.

Munich Motorcycles over in Western Australia. More costly, but much quicker delivery.

...and your local Dealer.

If you're buying parts from the good ol' US of A, just check the postage. It can get pricey!

Aahhhh, all is just fine, he's one of us, just on holidays I expect.
A few of my family have done the same, temporary migration (ten years so far)
I'm sure the guys up north will keep an eye on you.

AND check the fuel tank to see what sort of mess is in there. Don't just flush it and refill it. Have a look at the condition of the fuel pump rubber damper. It could/will be a gooey mess.

welcome aboard plowey ....enjoy the rebuild

God another Queenslander they must breed K clones up there or something you lucky buggers. My last bike was a spastic ZX9R fully modded (picture on one of my resto pages) with 155 bhp at the rear wheel (I know there's greater bhp now & Rick G's bike etc) but this was a 99 model) with no weight as everything was stripped off with just an ace dash at the front (about 180 kg) and I loved her to death, then I bought a $500 K100 and F**K has it changed my life & thoughts on what a good motor bike is, I'll be amazed if you don't full in love with it , there a real creeper.

Halo

Don't take too much notice of grover he is a bit fanatical as you can see he dyed his fur blue.

So far I have removed the fuel pump and the rubber damper in pieces, and there is what looks like a brown scale in the tank. I have started scrubbing the inside of the tank with scotchbright and it is coming up alright. I have also removed the injectors and rail. Only one injector is still worked and the fuel rail had a lot of surface rust also. The engine turns over on the start button, and there is pressure in the oil system and all the spark plugs are firing. Will try and post some pics of the bike tomorrow.

was told that single over head cam Hyundai Excel injectors have the same impedence and flow of the genuine BMW Bosch injectors and that form,fit function identical...stopped by the wreckers picked up a set on a fuel rail and will give it a shot....but there are definately other injectors tried by our members such as FJ27 and also those fitted to some mid 90's Australian and yank fords....the reason we are looking down this road?..the genuine ones are unbelievably pricey....and there is another excellent choice one of our own RJ Trucker does a fine injector refresh service in the states.

Maybe our USA brother can help out with postage. It cold be cheaper to send it to a US address then get them to send on to you.
Just A thought.

The injectors from the V8 fords of the EA -ED and Fairlanes NA & NC are the same thing

Welcome aboard - I also have a Kawasaki (1982 KZ1100 Spectre) but since I got Kpox the Kawasaki has had little use apart from nice sunny days (rare here in the UK). Embrace the new challenge - you won't regret it

As promised, here are some pictures of the new toy.







The last photo is what is left of the fuel pump, rubber damper and filter.

Yep I reckon that is the most corroded fuel pump I have seen yet and should be very good to throw at the cat next door.
I have bought many of the fuel pump bits from EME http://www.euromotoelectrics.com/BMW-K-Parts-s/60.htm?searching=Y&sort=13&cat=60&show=20&page=1

The most coroded? This was on my bench about 18 months ago. Despite the date showing it won't happen for another 8 years.

Hey Rossco I hope that was from the donor bike.....not the "bob the builder special".....

That was from my bike.
Replaced it before I bought the donor bike

Yeah yours is very dirty and rust and shit but the case of the pump is not corroded as that one is.

Yes Halo - apparently there is a woman giving birth in Queensland every 9 minutes......and if any one knows her would they please ask her to stop! :joker:

Welcome to the assylum Plowy, it's run by the inmates you know. Your K is looking a tad "under polished" but it also looks like you've made a good start on rectifying that. Goo look with it. I will follow your progress with interest.

Hi Plowy,
Great to have you with us and we will follow your rebuild progress in the "Your own renovation" section.
Regards,
K-BIKE

My pump looked like that after 5 years and it still turned so clean it and soak it in kero before you try turning it too much, you never know what will happen, I turned mine upside down and after clearing the gunge away it turned by flat blade screwdrive just gently fiddling and it moved, its not the one I'm using but thats because I dropped it whilst apart. Ya shouldn't drop things it seems

Hi,
I am happy to see a new member of the BMW owners community.
My story is very much identical to yours. I bought a junker bike from a reseller for $500 US, thinking I could have a happy time rebuilding it to nice condition.
My project ended up taking me 4 months and the bike is not fully restored, just re-conditioned.
To be quite candid with you, There are many many very nice K100's out there that are already very nice and need little if any repair, selling for anywhere between $2,000 & $3,500 (at least in the USA).
To be truthful, I lost track of how much money I ended up spending on the project, but my best guess would be in excess of $5000.00.
Admitedly, I made some poor choices along the way with some of the purchases I made for used or new items, but I truley wish now that I had spent a bit more on the front end to get a more "ready to roll" item, instead of trying to "buy cheap" on the front end.
attached are a couple of before/after pics.
If you do decide to go ahead with this rebuild, I would advise you to keep VERY close track of all the expenses.
Just for fun, I would be interested in knowing what your costs were when finished.
Good luck!
IBJ

Good job IBJMAN, a top effort and it shows ,
Plowy, it's stories such as this which give you inspiration to move forward to better things.
good luck with it all.

Thanks for the kind words.
In my earlier years I started out with a 100cc yamaha 2 stroke twin.
After that, I aquired a 1969 Moto Guzzi V700 from a family friend who could no longer ride due to health issues.
I sold that after I bent the front fender in an unexpected meating with the rear bumper of a Ford Pinto.
My next bike was new 1978 R1007, from Marty's Foriegn Motors in Torrance, CA.
After I crashed that I got a very nice used 1981 R100rs, Anthricite Grey. That was my favorite motorcycle till some Yahoo decided to make a 3 point U-turn in front of my lane just at my exit to a curved tunnel.
Next, I replaced the Airhead rs with a used 1985 K1000rs. I drove that about 70,000 miles with no mechanical troubles.
During that period I also had a 1959 Harly Sportster on a hard tail frame with ape hanger handlebars, a kick start, straight pipes and NO retarder on the distributer (a bitch to start). I also had a Honda CX650 for an additional toy.
During that period, my best friend passed away at age 38, leaving to me his 1970 Moto Guzzi V-750 Ambassador which I still own, but seldom start.
I wrecked the 85 rs one day when going WAY too fast in an industrial park near my work, trying to avoid a car that crossed my path. The investigating officer said he measured 62 feet of "locked front wheel skid mark" before I finally fell. After I repaired that one, I sold all my bikes feeling that I simply did not have the common sense to ride safely.

Now, 20 years later.......retired from work and sitting in my easy chair......I have come upon my "second childhood syndrom" and bought this beast.
It's a very nice bike and I've ridden it about 5,000 miles since getting it up to speed in late October.
To be quite truthful......it's just not as much fun as I thought it would be.
I'm longing to find a way to get some money out of this one and replace it with an airhead rs. I really miss the "soft" docile quiet glassy smoothness that I loved about my 82rs.
Unfortunately, they sold so many of the quirky 85 Krs's that they are a dime a dozen on the current US markets while the old airhead rs's are going for premium $$$$$$!
I will continue to re-evaluate.

I would like to thank everyone for making me feel so welcome, and all the tech advice and encouragement from everyone.
The plan is to restore the bike doing as much of the work on it myself, including spraying it. I will get it running first to make sure there are no mechanical gremlins and then strip it and rebuild it to as good as new.

fantastic result ibjman

there are so many dedicated and talented folk here ...it amazes me no end

good luck plowy ...when you need inspiration ...check out some of the restoration threads ...they are absolutly brilliant

I have just been having a look on restoration threads and think I will start a thread for this rebuild.

Really like the motosport roundels, adds a nice touch.

I bought a 1985 K100 RT a few months ago and immediately started the teardown. Between the Clymers and BMW microfiche it's been easier that I thought. I have a post running on the Your Own Restoration forum.
Like some of the other members have said it can quickly get out of hand buying parts. I pretty much used OEM parts for everything. May do it a little differently next time, which I'm already planning...
