What Did You Did To Your Motobrick Today ?

[Photog]

Got everything back together from the replace rear seal/o-ring/clutch disk/lube-the-splines/replace-vent-hose/clean-the-starter-innards/upgrade-battery-wiring project.
But found that it didn't like going into neutral with the engine running.
Re-checked the clutch adjustment, discovered it needed some tweaking.
Yeehaaa time now  :2thumbup:

Big improvement in shifting.

Next up, Vision X fog lights with heated grip switch circuitry documented by Duck, and an LED kit for the instruments

Re my 1986 K75S:
Re-assembled front mudguard (remember to fit the rear part of mudguard on the fork legs before fitting the front piece - it saves a lot of frustration).
Drained old gearbox oil, condition OK, level at very bottom of dipping tool, therefore too low.  Relating this to oil and grime on underside of bike, on clutch actuating lever and base of final drive, possible cause is a failed oil seal  on the gearbox output shaft? That at least is a working hypothesis.  (The crush washer on the drain plug was badly chewed up – and the plug hard to remove; another instance of over-tightening syndrome.)



 

ng syndrome.)

Having removed the petrol tank I used a compressed air blower and a soft brush to remove dust and debris around the frame and wiring harness. Then I started to clean up electrical contacts using an aerosol spray intended for that purpose (unfortunately DeoxIt is not distributed in SA).

heat shield for repainting

Consider ceramic coating it.  Cost me $25 at a local shop.

Thanks Duck, I'll check it out.

Front master cylinder refurb with new plunger thingy from Beemer Boneyard.

The rubber seals on the old piece looked pretty tired. Hoping the new piece clears up the weepage I've been having.

Scored a brand spankin new Aeroflow for $65 on Ebay.  Nobody else bid! Could be they had it listed as a K755 instead of a K75s.  Now i just gotta paint the rest of the parts and bolt everything together and my S will LOOK like an S again :clap:

Hey Chaos -- hate to see you leave the Meier fairing club -- but congratulations on all the new plastic!

[Chaos]

Yeah, I doubt there are many meier modified K's out there.   I missed the extra protection from the fairing and bigger screen though.

Changed tranny oil; amazingly it shifts far less clunky-er now; is this possible? or , am I dreaming?

For the collective group  - how does one check the tranny oil, i tried the curvy-wrench backwards into the hole trick and came up empty.  Other ideas?

[frankenduck]

came up empty. 

What do you mean by this? :dunno

[sh00ter]

came up empty. 

What do you mean by this? :dunno

Sorry, I meant I tried using the curved wrench that came with the kit, I read somwhere that sticking the long end into the tranny fill plug would give you a dipstick of sorts.  When I tested this (pre oil change) there was nothing on it; does that mean it was low or my methods suck?    :biggrin:

[frankenduck]

Only the 2V shock wrenches have a line on them for checking the trans gear oil.  Look in your tool kit for an L-shaped piece of metal:

Got it.  No wrench like that; I'll build one. 

[Roy S.]

Thanks Johnny for the Geva Cover information. I'll will be talking to the company to tweak it a little

[frankenduck]

Nice score there, Roy! :mbird

(And nice job tying down the front end. :yes)

Thanks... I got some great advice from this cool site http://www.motobrick.com/index.php/topic,2101.0.html

Back brake pads
New spark plugs

Complete 10,000 mile service this week, parts came in to fix the bracket for the bottom cowling and turn signal lens, ready to ride to Hungry Mother in less than 2 weeks....

ROAD TRIP !!

[Chaos]

Prepping and painting the nasty yellow bodywork I scored from BBY.  This is going to be a unique K75s.  Also pulled the very dirty starter to clean it up and hopefully fix my no start condition.  Damn thing would not come out for hell or high water, then I grabbed it from a different angle and it almost fell out.   :biggrin:  It is REALLY dirty!

BabyBlue got a pair of three spoke wheels and a new Works shock

Just starting to tear down the K1100RS for a spline lube. Last done 6 years ago with 14K on the clock, now at 36K. Doing this a bit at a time each evening to give me time to decide whether to replace the clutch nut O ring or not while I'm in there. Never had the clutch off before - can't be that difficult, surely?

I used to be undecided but now I'm not so sure.....

I'm kinda leaning towards leaving it alone. The bike is low mileage but is used regularly and has not stood for any length of time in the 12 years I have owned it. I will tear it down and if there's no sign of oil I will leave it be. Off to the garage now to get the FD/Swing arm off.

Re. refurbishing 26 year-old K75S

(1)  Having removed the petrol tank I drained the remaining fuel, cleaned and inspected the inside of the tank.  Fortunately there is no sign of corrosion and I know the fuel filter has hardly been used.  Fuel lines and sealing washers look to be fine. One of the rubber grommets that secure the tank on the frame had split in two and I need to replace it when I next order parts from BMW.
 
(2)  With the tank off I continued the work of cleaning up and protecting electrical contacts.  Today the ground connections under the tank, close to the steering head got the treatment: cleaning up with a 400 grade wet and dry abrasive sheet followed by a good spray of Spanjaard Lectro Kleen (substitute for DeoxIt).

Did This Really Work?? It somehow seemed way too easy.

Balanced my throttle bodies today with this method:



 Gotta admit, I may not be the best on-camera talent  :tongue


The only thing I find perplexing is that when I get things perfectly adjusted at idle, when I twist it up to 5k, the levels start to move again.
Is that ok, and should I just stick with the reading at idle? or should I get someone to hold the the throttle open at 4 or 5k, and quickly adjust it so it reads even there ???

After bricking my way to the coast from my dad's place on Sunday on some of SoCal's finest motoroads, I made it to the coast south of Big Sur, set up my tent and watched the sun set on The Pacific.  It doesn't get much better than this.

On Monday morning, I broke camp and headed north on Hwy 1, truly an epic morning with Hwy 1 all to myself and destined to be the greatest of motobricking days.

BUT when I hit Carmel the hose from the radiator to the water pump blew about a 3/4" gash in itself and peed out most of the coolant.  I made it to Santa Cruz until the dreaded Motronic overheat light came on so I pulled into a parking lot and was forced to do something about it.

I called the two BMW dealers that were within 25 miles of me but my bike made the mistake of blowing up on Monday, when all of the dealers are closed.

Fortunately, I found a shady parking stall and there was an auto parts store only a couple of blocks away.  The radiator hose repair tape they had was complete shite but I was able to effect a temporary, though still somewhat leaky, repair with that and some zip-ties.

My public workspace:

I called Roy S. and asked if him if he could put me up for the night if I were able to limp to his place.  Being a true morobricker he said no problem.  Once I had things together and some coolant back in it, I hit the road. With a little experimentation I discovered that the speed which balanced the heat generated by the head against the cooling of the wind rushing past to minimize the stress on the cooling system was about 70mph.  If you have a crippled bike that needs to get somewhere 165 miles away then 70 mph is a good thing. :2thumbup:

I made it to Roy S's place a little before six.  He was already taking the low seat off of his recently purchased K75RT so that I could use it to retrieve a new hose from A&S in the morning and wouldn't be cramped riding a low seat but put a Corbin Dual Tour on instead. (Fingers crossed that they had one in stock.)  Not only that but he'd gotten me some fresh Heineken which was coolly waiting in his garage fridge and very much appreciated.  Roy certainly has earned Motobricker of the Week/Month/Year for how helpful he was to me. :mbird

I called A&S BMW right after they opened at 9am and they confirmed that they did indeed have the needed radiator hose in stock.  (I asked the guy I spoke with to physically confirm that they had it on hand because computer inventory and real-life inventory often differ.)

So then I took Roy's "new-to-me" K75RT for a 30 mile ride up to A&S to get said hose.

And then I installed it.

Thank you very much, Roy.  I know that it probably wasn't a big deal to you but the help you provided me was invaluable. THANK YOU! I owe you one.

Ah, Big Sur and Hiway 1. Someday...  Glad you had a gentle landing there, Duck.
