These are the details of the bike taken from some vin id site

Chassis number 6308802K100CJ
Vehicle code 0521
Series K589
Model K 100 88 (0521)
Body type ohne
Catalog model ECE
Production date 1988 / 05

Punched the VIN into RealOEM to get all the info on parts and I cannot find anything for the bike listed.

Not going to be doing a lot of riding till I get it all sorted.

On initial inspection it needs stuff.
That fairing is coming off. It is original Krauser, has a number stamped on the inside and the manual in the boot.
Sitting behind that thing is like listening to a shuttle launch. The wind is directed straight at the helmet. It is loud and relentless. May look at some sort of extra deflector to go on top. May not.

Come on up Halo. Got a spare bed, 2 dogs to cuddle, 4 bars of sunlight soap and enough steel wool to (add your own witty comment here. I am too tired)

Rear master cylinder seems kaput (German word Sean?).
Half way home opened the reservoir and it was empty. Not a drop. removed the boot at the pedal and it all came out.

Gearbox was getting klunky (another German word?) with heat and time.

Forks were very soft and dived a lot under braking.

Electrics seem fair. Lights work. Right indicator was turning on by itself in the rain, but it was a lot of rain and did not do it again after I pulled the switch off and wiped it with my shirt.

Brake indicator light was blinking on and off but only faintly. You could only see it in the dark.
Gear position indicator was flashing between the correct gear and any number between 1 and 5.
Tacho is happy doing just what the hell it feels like at the time. Seemed to settle at about 4.5k engine speed, but less than that it was up and down like tassels on a t..

That's about it for now. If anyone can find those elusive numbers for the headlight parts I would be happy. Email sent to Motorworks asking on availability.

Lets see if Bob does a better job of building this one.

Photos when I get home.
oh, as for the riding position? Col I think this one is for you.
Yes, those handle bars do come back to almost the filler cap. It is like steering one of those ride on lawn mowers with the handle that swings left to right.
Having said that, the riding pozzy and bars make full lock u-turns a breeze.










Hard to see, but the fairing is 2 colours of...lets call it red.


The fairing repair. Professional job.


Previous owner had an off. Looks like it may have worn through the rocker cover. That is oil on the outside.


For those interested in the under parts of the seat, here it is

I took the frame number of mine to ProCycles at St Peters and they did a chassis lookup. It confirmed mine was a Japanese market bike including an automatic prop-stand and adjustable seat. Can't see any adjustment for the seat...


Is the headlight held in by the fairing or are the original bracket?

I changed the fork oil to 10W a couple of weeks ago which made a hugh reduction in the brake dive. Original fork oil was very thin and tired looking.

Basic2,
This is what I got for you using the VIN decoder

Well done Rossco the tacho and gear select will probably be the internal connection pins that are easy to get to when you open the dash.

Well done Rossco...but I am concerned that I have started something that is now out of control. Last year I was TOLD to get a second bike to keep my mind going and now you and RT get seconds at about the same time. Halo got a second a couple of months ago. Where will this madness end?
Look foward to your progress.

Ok Rossco, all the excitement is over. Get busy, and first thing is to check out Halo's job on his exhaust. Man there is some work ahead.

Strange you seem to think there was some sort of control in the first place.

Sorry to disapoint RT. Have you seen my chrome heat shield? and it doesn't rattle.

Rick, no clips on the tank

So Rossco my place or yours for a maintenance day?...oh yours may be better cause you have a spare bike....heeeheee

I feel left out , only having the one.....once I get a little more fluid shall look again for a suitable beasty.

Why does it say is it a keeper ? Of coarse it is it has entered your clan now hey Rossco mate

Here is the headlight.
Here is the housing.

Congrats with the new bike, about the GPI...check the connector at the right side of the battery.

Where you also can simulate the different gear positions by grounding the three signal wires in various config.....and also check if the switch is OK.

Great pictures love the seat and black plastics around the tank

Thank you Sir Inge K.
I did find the headlight link but not the mounting.
I should have just said "Hey Inge, what is the part number for the black bit that sits behind the black bit that holds the silver bit that shines the bright bit on the dark bit as I ride in the night.
Stupid me. Now I know better.
As for the gear numbers and 3 pins.....um.
I do know what the switch looks like as mine was in 27 pieces in my hand and on the floor last time I checked it. I will start with that.

That headlight mount looks to be pretty cheap. Might get 2. or 3. Corner the market.

About the GPI, at the connector you got 3 signal wires and ground....
and the 3 signal wires is grounded in various config.

1. brown (ground) and yellow/white + yellow/black connected.
0: all 3 signal wires grounded.
2. brown and yellow/white + yellow/blue connected.
3. brown and yellow/white connected.
4. brown and yellow/blue + yellow/black connected.
5. brown and yellow/black connected.

Hey Rossco is this any good?

If yes, I'll bid for it and post it on.

Paul.

That piece is for the early version naked, Paul.....it isn't used on the later one.

OK Inge, was worth a try.

Not a bad idea at all, Paul......a complete headlamp mount for the early version could also be used.
These parts would be easier to find, as a lot more was produced.
But the later version got a much nicer design....is my opinion.

Thanks for keeping an eye out Paul.

Inge, does that mount sit on top of one of the big plastic bits that holds the naked headlight?
Part number 1 in this diagram

I thought that it was part #1 you did have in mind, since this is the black bit which sits behind the black bit thats hold the silver bit that shines the bright bit on the dark bit as you ride in the night.

Good one Inge.

Excellent Inge. Silly me just read your reply and thought 'oh yeah, that is what I am talking about'
Then I clicked the links.
Most excellent work.

If you're gonna search used parts........same parts was used on the naked K75.
The headlamp housing was available both in chrome and matt black versions.

What do you think of the Michelin Macadam tyres Rossco?

Hmm...those ones most start to get old...Macadams went out of production
at least 3 years ago.
Check the DOT code.

Basic2 wrote:What do you think of the Michelin Macadam tyres Rossco?

Unsure. The riding position of this bike is so different to the RT that it is hard to compare the two.
It could be the tyres are crap (old, as Inge suggests Early 2009) or it could be me.
Whatever I will be putting my Pirellis on it as soon as I can.

I had a Michelin macadam on a spare wheel which although the same size indicated was heaps wider on the rim and felt bad accordingly....the Pirrelli I have recently put on is excellent....although the previous rear Lazer was totally benign and predictable the bike did not want to fall into corners as it does now.

found a good recent pic of the headlight rossco (from bmw k75 -100 group on fb )

Hey Rossco, have you changed your fork oil?, made a big difference to me, although I am a slug on the road, but felt
much more confident.
RT

RT are you now a confident slug?

RT

Only oil I have not changed yet. I still have my Inge Bowl from last time and I got some 10w oil and 5w oil. I will give them both a run.

The bike seems very 'tippy'. When I get into a corner it just seems to want to go and it feels like I have to hold it back. We are talking low speed suburban road corners here. It was fine on the big sweepers on the road home from QLD.

Nice picture Charlie, it shows a K75 with a headlamp holder/surroundings from a early naked K100, which isn't the same which been factory mounted on Rossco's bike.

For some good recent pictures, take a look on the new spanish member Punto's bike here.........which is the same parts as used on the K100/II.

Thanks Inge. Thems the bits.

Got Tez at Motorworks on the job for me. They really are a helpful bunch there.
Seems the mounting part I have (the black bit) and just need the surround and the screws etc.
Fingers crossed the big as headlight I have is going to do the job for me.

I also sent an email to chattanooga BMW folks explaining the K100/2 etc and he denies the existence of my bike. Sent him a photo. I know I rode something home from QLD.

They'res three of us now on the forum - we're taking over!

Thanks inge ....i see the differences now ...

good luck rossco

Basic2 wrote:They'res three of us now on the forum - we're taking over!

Don't say things like that Bert just might say you can do it and you're welcome to it.

They only made 3 as they didn't corner very well, sold the plan to Harley somebody.

Slug.

Not that strange, this model doesn't exist on the US market.

Also the first naked version was removed from the US market after a rather short time....due to the low sale numbers.

OK, Inge, the 83 basic I have must be very rare thing....perhaps more valuable?

ainsjac wrote:OK, Inge, the 83 basic I have must be very rare thing....perhaps more valuable?

Maybe only to you Stan.
Because this bike has no fairing it is worth $1000 less to insure than the RT.
Guess they are as valuable as much as someone wants to pay. Is that even english?

Looking the goods there Rossco, will be waiting to see how it all turns out.

Do you still need zorst? Have a spare here to mod.

Good luck with it all.

So, as mentioned I did the fluid changes. Fluid changes Blakey, not fluid exchanges. I know how your mind works.
Pro tip. Measure the oil.

I have a question.

So i had some oil left over from something. A bit of Caltex and a bit of Shell. Both 20/50.
I figured it was about 4 litres. New filter, fully drained, should come close to being enough.
Sight glass is a bit yellowed with age.
Added the oil. Watched the glass. Shone a torch on it. Eyes not as good as they used to be. Obviously.
Didn't see it in the glass. Damn. Must be close. Better get some more oil.
Next day.
5 litres of Shell ( as that is what I had most of to start with) and started pouring. Eagle eyes on the little window all the time. Nada. Kept pouring. Still nada.
3 litres of oil on top of what I had.
Something aint right. How much did I start with? was it 2 litres or 4?
Then the brain had a fart and I thought 'well I should just start the old girl and see what happens'
Seemed strangely hard to start. Blue smoke. Idled kinda laboured. Turned her off and she stopped like someone had stuck a broom handle through the rear wheel.
Too much oil? Did I miss something?
Put a 5 litre saucepan ( shhhhh don't tell her) under the sump and cracked the plug.
Filled that.
Emptied the pan.
Cracked the plug.
Came close to filling it a second time.
Woops.
Got a better torch to watch the glass as I filled it.
Right on the dot. Runs like a dream.
Is it ok to mix oil brands?

Guess they are as valuable as much as someone wants to pay. Is that even english?

No, it's Australian. Well I understood what yooo sed.

No Rossco
do it again.

perhaps they should make darker oil so you can see it?...lol

Being brutally honest those nakeds were butt ugly ! There, someone had to say it !
However as Inge said not many were made (sold ) so Rare apparently . And maybe worth more ?
I always thought mine was less than pretty but guess what ? when riding the ugly bits aren't in view !
Go the hog Rossco , that Krauser looks rubbish anyway !

Yeah that Krauser doesn't do much for me, about the only aftermarket fairing that I have seen that I like is the Sprint.

Now that you have a bit of 20w50 left over why not try using it in the forks, I've just read that it gives a better feel on the front end.

Going to swap handlebars and wheels from my old bike to the Basic this weekend and see what difference it makes.
Still undecided if I like the riding position.
Might just give the old girl a good clean, replace the fairing with original parts and sell her off.
I can only have one registered bike and I really don't want to lose my original RT after 18 years.
