As I am new here and new to K bikes [bought 88 K100LT 31 Dec 2015] I have read the first 35 pages of this thread today and started making a list of all the things I have to check before my first ride on it ! Winter here and a no heat garage limits what I can do for the next 2-3 months...... so just read, plan and learn ! The 1/4 mile gravel driveway where I bought it proved it ran so I brought it home in my truck and now waiting for spring.

That's what I did today !

front brake lines replaced with Spiegler braided.

finished cleaning and straightening up the wiring. choke light works!

airbox and AFM reinstalled

"while i was in there" ran unswitched power and ground from battery to fairing to drive light relays.

the pile of 1993 dated hoses...

now that front of bike is done, time to take apart the drive line and pull tranny for spline lube.

Marshall - this is a proper going-through. What do you think about recapping all this work in a project-bike thread? Maybe you could copy all your posts in the "what did you did" thread. It would be cool to be able to read about what you're doing (and continuing to do) all in one place - the order you're doing things is really helpful.

I'm eager to get into mine at this level too - but I keep leaving it at airports (where it is again this week.) I'm going to do front-end, then back-end just as you have done - I got the spiegler lines too (but I'm doing ABS-delete). You're making me think about replacing all the coolant hoses as a preventative measure. Where did you source them?

Bill, congrats on the new brick!

May I suggest a few things you can do even in the clutch of winter in the great white north. Drain the gas in the tank, replace with 12 liters of fresh gas(corn free if you can get it) and a bottle of Chevron Techron fuel system cleaner.

Get a small trickle/float charger that has a plug that will fit the accessory outlet near the coils. I have one of these(wait until they become available again):

http://www.ebay.com/itm/For-Hella-BMW-Powerlet-Motorcycle-Automatic-Smart-Battery-12-V-Trickle-Charger-/121206035696?hash=item1c387154f0&item=121206035696&vxp=mtr

Every 2-3 weeks plug in the charger and let it run over night until the LED turns green. That will keep your battery nice and fresh. Then run the engine for about 5 minutes or until you can feel the radiator start to get warm. Enjoy the sound of your brick engine. This will circulate the oil in the engine and more importantly the Techron loaded gas through the system which will spend the winter dissolving any crap in the injectors.

Already got a battery maintainer on it a B&D model to charge and then float. While I wait for spring once a week I do start it just to hear it sing

Looking for a Techron equivalent here in Canada that will clean the fuel system. My list to complete before spring is plugs, oil/filter and check all the rubber bits. Mostly just to get familiar with what I read about .....

Sounds like you're on top of it!

Bill · « **Reply #1831 on:** January 18, 2016, 10:24:18 AM »

I do swing a leg over but it makes the noises for me ! Also on the list is to check what mods have been done to it electrically. Has a Supertrap muffler but the PO also gave me the original with header pipes ....

Will do!

I have a 50 page build thread on another forum for the building of my 1975 bmw 2002 track car. I tend to document everything I do.

Wish I had that kind of discipline. I want to document what I'm doing, for future reference, but I gwet involved in what I'm doing and suddenly realize I am beyond the point where I can take some good photos of how I got there.

And I used to write technical manuals with photos in the past...

i have over 2300 pictures taken over the five years of the 2002 track car ownership, modification, driving and tuning posted. the build thread is part documentary, part how to, part novel, part social event....

i take pics of everything primarily because, well, i forget how i take stuff apart... helps to get it all back together!

After a low battery incident I had a flashing ABS light issue so having read Frankenduck's excellent ABS Voodoo thread I started work. First problem - the ABS light switch fell apart as I removed it as it clearly wasn't working. Cleaned and rebuilt the switch, then re-soldered wires back onto the connectors, then refitted it. Followed procedure to clear flashing light - and it worked at first time of asking. Yet another success for Motobrick and its wealth of no nonsense and easy to follow knowledge. Thanks to all contributors. Forgot to say, after finishing the job I went for a spin - hence the silly grin on my face.

Discovered wear on the front brake hose from rubbing the bike.

Brought the hose to Olympia Custom Hose and he made me a new one on the spot for about $60. Found out when I got home the top connector is actually 2mm too thin, but a couple of extra copper washers seems to have solved that problem. Front brakes are solid now.

K1300S · « **Reply #1837 on:** January 20, 2016, 06:35:06 PM »

yikes! was that line original? what was it rubbing on?

TimTyler · « **Reply #1838 on:** January 20, 2016, 06:37:25 PM »

Line was about 4 years old. Not sure what it was contacting. Up until last spring I did not have a fiberglass radiator shroud so maybe it was rubbing the radiator.

dark_gap · « **Reply #1839 on:** January 21, 2016, 09:23:51 AM »

Well, so this is my second post...today I have bought:
- New Exide battery
- 20W50 Castrol mineral engine oil
- Castrol SAE 90 API GL5 transmission and final end oil
- A bottle of DOT 4 for change the old brake liquid.
- A pair of fork seals and dust seals (41,7x55x7,5/10) and SAE 15 fork oil.

And this afternoon: mechanic time!!

Only one question: Its to much for a 88.000kms bike the SAE 15 for the front forks? I use it in my other bikes to compensate the spring deterioration...

This is a question that you should answer yourself, d_g. You've ridden the bike. Do you know what grade of oil is in it? It will only take you a few miles over rough pavement or gravel roads to discover whether SAE 15 will work for you. Changing the fork oil is a relatively simple operation.

rbm · « **Reply #1841 on:** January 21, 2016, 12:00:15 PM »

You're in Spain, which is a generally a hot country, so maybe SAE 15 is correct for those conditions, your weight, riding style and setup. Double check the sag adjustment on the bike and make sure rebound is equalized between the back and front. Then ride, as Laitch suggests, to determine if a lighter oil like 10W is required.

Connected up the battery after a 2.5 month lay-off for my work trip to Antarctica and she fired right up no problem at all. Short ride around the local area to check everything and the bike was running beautifully. Rotated the bars a little towards me (PO put C bars on) to see if I can ease the shoulder pain I sometimes get, felt good but time will tell. Well pleased to be back on the bike on a lovely sunny day in the green fields of the UK.

I'm sure they will have an amazing time. McMurdo is an interesting place with more than 1000 people there, stark contrast to the 45 that were at Halley station during my visit.

So finally I have choose SAE 20, two friends with a R100 and R100RS have done the same operation and recommend to me this viscosity, so I'll try first this one and If I'm not happy I will go to a lower degree to SAE 15. I'm 1,80 and 89kg so hope will work for me.
Thanks for the answer!

Hi rbm, thats one of the trickiest thing for my in new bikes, setting all the bike as I want to. There's any DIY in the forum to do it? I have the workshop and owners manual...if I can find there will be great cause is a completely new bike and a new transmission that I've never tried before...so I'm really lost here

Thanks!!

Read these two threads, d_g, if you have not already.
http://www.motobrick.com/index.php/topic,370.0.html
http://www.motobrick.com/index.php/topic,339.0.html

Otherwise, the Workshop section is where most of us do our research on procedures unfamiliar to us. The section is divided into component groups where you'll find plenty of advice, opinion and useful information.

rbm · « **Reply #1849 on:** January 24, 2016, 10:04:29 AM »

SAE 20 is very thick fork oil; BMW recommends Esso Komfort which is a SAE 10W. You'll feel the suspension to be much firmer on compression, which will also mean it will be harsh on sharp bumps, such as cracks and holes in the road. Also, the rebound will be slow, meaning it will feel unstable in corners where the road surface is uneven.

The total fork travel for your K1 is 135mm, and therefore you should be targeting for a 45mm sag number. There are a number of articles and videos on the Internet that explain setting dynamic sag. Videos on Youtube by Dave Moss are the best out there. His explanations are centred around track bike suspension needs but the theory he talks about is universal and applies to the K1 as well. To adjust sag on the rear is to screw in/out the preload adjuster rings. To adjust preload on the front forks requires the forks to be disassembled and the preload spacer tube shortened or lengthened. That is major surgery.

Here are links to 3 Dave Moss videos to get you started.
