Well things have slowed down over the past two weeks. Just about all the major items I wanted to attend to are done:
-New fuel pump, filter, float gauge, hoses.
-Cleaned tank
-Flushed and cleaned radiator. New fluid.
-Fuel injectors refurbished, fuel rail cleaned, new plugs gapped.
-Instrument cluster taken apart and pin connectors cleaned.
-Cleaned speed pulse sensor at the final drive and electrical connectors.
-Removed final drive. Cleaned and re lubed splines.
-Rebuilt rear master cylinder. Bleed rear and front brakes with new DOT 4 fluid.
-Took apart and cleaned rear calipers.
-Front turn signals were not working so removed and reconnected the wires. Removed some bulbs that were put in there for heat.

So now I will be reinstalling the lower fairing and knee pads and taking for a test ride. The weather has turned somewhat cooler and the days are shorter so work in the morning is limited.
If all checks out the bike will be ready for winter storage until next spring when new funds should provide the means for continued restoration.

Thanks, JT

Took the K for another test ride last week and was very pleased with the bikes performance. The rear brake is working nicely and the speedometer that was not working a month or two ago, is now working. Rode around for  a few miles and the odometer is working too.

I am going to be storing the bike soon for winter in my garage and resume work on it next spring. A friend who has had many bikes, and currently has a Harley Sportster and a Kawasaki ZRX, says that he uses Lucas Fuel Stabilizer. Anybody have experience with this or other products?

How late in the fall do folks ride? Or is anybody riding throughout the winter here in the Northeast?

I have used STA-BIL fuel stabilizer for 20 years in 10% ethanol gasoline for motorcycle storage and all my chainsaws and brushcutters. The equipment remains in good condition. It's not plagued by gasket or hose deterioration. I use or replace stabilized fuel within a year. Usually it's used within six months.

Do you fill the tank with fuel then use 1 oz. or 30ml per 2 1/2 gals. of STA-BIL like it says on the bottle? So you would use 60ml for 5 gals. tankfull?

I put the lower fairing panels and the knee pads back on and ready for winter storage.
Question: Does anyone use the Beltran Battery Tender and if so, what amperage? I was told by MAX to use less than 2 amps. I see they have a 750mA Tender Junior and a 1.25A Tender Plus.
I have the Westco 12V/30AH battery.

Thanks.

Fill the tank with kerosene or 50/50 petrol/kerosene and run it through the fuel pump and injectors for the winter hibernation.
The moto petrol components will be well preserved during there slumber.

Put a cup of kerosene in the crankcase oil and run the moto to circulate kero through out the engine

Squirt some kerosene or Marvel Mystery oil or penetrating oil into each cylinder

0.75A-1.25A is optimal charging setting

Fully charge battery then remove negative ground wire from battery

Ha, you saw that ad? I put it up kinda high to see if there would be any response but nothing. I wasn't too surprised so I figured I will put it back up next spring. Give me more time to fix up a few things.

What is the little accessory port above the coil box used for?
It has a spring loaded cover that flips up.

Power your electric jacket and undergarments from that outlet
Its wired direct to the battery
Plug your battery charger into it if it has the Hella or Powerlet BMW type male end connector

Most auto accessory or electronic outlets stock them, they are also called Merit plugs. You can also get an adapter lead to convert Merit to standard cigarette lighter socket.

Yes. I'd use 600ml for 50 gallons, 900ml for 75 gallons, 1200ml for 100 gallons, 6000ml for 500 gallons and 60,000ml for 5000 gallons. I'd keep a running total in my fuel log and Fuelly account. I would log and compare mileage with or without STA-BIL using ground speed, wind speed, temperature, load weight and atmospheric pressure as variables, too and include photos of baby animals encountered during field trials.

Your strategies are admirable, I think I will mimic them.

I've got three bricks in the garage now, and have owned five over the past six years and they have all done nicely on my storage regime.

First, I do all the annual maintenance, splines, brakes, fluids, valves, etc.  Then I fill the tanks with no-corn mixed with Stabil and Techron. 

I'll apply a light coat of a corrosion protectent concentrating on the lower parts of the bike being careful not to get any on the brake rotors, I use the stuff from S100.  This helps protect them from the puddles of saltwater that drips off the wife's car.  I cover them with those lightweight $20 motorcycle covers I get on ebay to keep dust off.

Every couple weeks during the winter I'll go out and start them up, letting them run at fast idle with the transmission in first or second gear until the engine gets warm enough to cycle the fan.  This charges the battery, gets rid of the condensation in the crankcase oil, and circulates the oil in the transmission and final drive.

I got a couple cheap $15 K bike trickle chargers on ebay that I'll plug in once in a while to see how the batteries are doing.  They have an LED that goes from red to green when the battery is charged.  I connect the charger to the power outlet above the coils.  Usually the LED is green indicating a fully charged battery that isn't low enough to start charging.  If I turn on the ignition and headlight, the LED turns red, and if it goes back to green in less than an hour or so, I am pretty sure the battery is fully charged, which means the battery is holding it's charge.

Last, and this may be a sign of a serious neurosis, but I check tire pressures once a month, and rotate the front tire a quarter turn to avoid having the weight on the same spot all winter.  The first year I had my K75RT it sat for four months on a soft tire which made a flat spot that took a couple hundred miles to get rid of.

Power your electric jacket and undergarments from that outlet
Its wired direct to the battery
Plug your battery charger into it if it has the Hella or Powerlet BMW type male end connector

It looks like from the diagram that there are leads with ring connectors at the end. These go on the + and - battery posts? they are not on there now. There is a battery tender SAE plug connected to the battery but that's it.
This Merit plug can also be used in reverse, to charge or tend the battery? You would need the charger lead to have the Hella or Powerlet BMW type male end connector?
I have not seen a charger with that type male plug, only the SAE type.

Thanks for the link and PDF Volador. $12 is not bad for the 030-0111 plug. I guess I would have to cut off the SAE plug from the charger and screw the leads on the Hella plug.
Do any chargers come with the Hella or BMW Powerlet plug?

I have had a fair amount of trouble with intermittent connections in those BMW power outlets above the coils.

The problem is that the negative terminal doesn't have a good electrical connection to the connector.

Now I remove the connector and carefully solder the terminal to the connector after cleaning well with Deoxit and 600 grit paper.  This is important because I use that power outlet for my trickle charger, and that bad connection makes the charger look like the battery is charged while preventing the charger from charging the battery.

This is what I use.  Be aware that although they have worked well for me, the low price probably means it will set fire to your bike and make your hair fall out.  Other posters here will confirm this warning and advise you to spend more money.

That is exactly what is needed. I think I will either get this, use the Merit socket with the Battery Tender Junior (750mA), or just use the Battery Tender Junior with the eyelet adaptor directly to the battery. Or just start the bike in the driveway once a month as Gryph says "Every couple weeks during the winter I'll go out and start them up, letting them run at fast idle with the transmission in first or second gear until the engine gets warm enough to cycle the fan.  This charges the battery, gets rid of the condensation in the crankcase oil, and circulates the oil in the transmission and final drive".

Wow, $193 list for that? I think I'll stick with the battery tender junior. It will connect directly to that SAE to BMW DIN adaptor you showed me.

One more question about the Merit/accessory plug;
Is the wire that leads off the back hardwired into the battery leads? Looks like it goes up under the relay box somewhere. I can't trace it without removing the tank etc. so was hoping for a quick answer.
I don't see any wire going directly from the Merit plug to the battery terminals.
Now that I look at the part diagram, the wire is terminated with those little slip on flat connectors (not sure the name?) so would probably connect somewhere other than to the battery terminals.

I would think if is connected to the battery it would have power going to the plug and could be tested with my volt meter but the volt meter is dead right now. Can it be tested this way, by touching the inside of the plug wall - and to the + at the back of the plug?
