webcam at the local newspaper office. Note the lack of traffic at what would normally be our "rush hour". You'd expect to see at least a couple of cars. As the article says, "This is not the kind of weather most Alaskans like," "We'd be happy to swap.".

On another note, I just heard from Aerostitch and they are waiting for the grey material for the bulk of the suit. I am surprised to hear this as I thought it was made in Southeast Asia and they just imported it. If I wanted a different color they could get it completed earlier.

This morning, I was looking for some other locations for sunrise photos plus I really wasn't feeling too good so I went for a walk. And wanted to post something other than a torn down bike. This is looking southeast from the lookout between upper and lower campus. And this photo is using the built in HDR setting in the standard photo app. Much more subtle than the ProHDR app that I have used in the past.
As far as the photo, I really like the frosty look the trees along the roads. I think they pick up a lot of frost from the water vapor in vehicle exhaust.
This is the view looking at the transmission input shaft n.b. the shiny areas and how it seems pretty dry. No major wear but this maintenance was needed. The splines shown fit into the clutch disc located on the left. Kind of dirty but not too bad for 31 years and 75k miles. The front of the transmission is on the right.
According to "experts" on the forums, the preferred lubrications is Honda Moly 60 though I mix it with some arctic grade grease to make it a little tackier. I brush it on the transmission input spline with a disposable brush stuck on the end of a chopstick. I picked up this tube in 2008 and have used about a quarter of it since then. It is also used on the rear wheel splines and the gear drive for the throttle cable.
This is after the application. Not much is needed. The transmission is simply slid back into place and the transmission mounting bolts reattached.
The swing arm pivots were cleaned and reinstalled taking care to re center the rear swing arm in the frame. Since it is very difficult to actually measure the gap between the body of the swing arm and the frame, I simply stick a fingertip into the gap and measure by touch. Then double check by eye before torquing the pivot lock nuts down. Total time for this entire maintenance task was 15 minutes due to all of the other pieces already having been removed. The first time I performed this task it took the better part of a day.
The new alternator did not arrive yet though the USPS tracking site says it left Anchorage Wednesday morning. I'm expecting it today. This was another attempt at blogging directly from the phone. The only negative is the pictures link into some Google+/Picassa no-mans-land with pages and pages of all of the pictures that I've used on the blog instead of the specific photo. I modified the href tags but it is still not what I want. After all aren't these fascinating photos that you HAVE to see in vivid detail ;-)
Maybe blogging directly from the iPhone is an unrealistic goal...

Just thought I would post a couple of shots of my mess… uh repair. This is the front of the engine centered on the rotor. I pulled off the rectifier bridge assembly also referred to as the "diode board". It still had the stock rubber mounts which commonly fail when they deteriorate with heat.There are multiple, exposed plates on the diode board that are "hot" so any contact with the engine case wouldn't be good. The contacts were so corroded that some of the spade lugs pulled right off when the connectors were removed.
The mess in front of the bike where most of the work is being done. I pulled off the stator, the stationary part of the alternator, but removing the rotor requires a hardened steel tool which has been shipped with the alternator. All of the plastic insulation on the wiring in this area seems brittle. Probably from numerous heat/cool cycles over the last 31 years. All of the wiring has been removed with the exception of the ignition wiring. The new alternator has only two wires that will be run to the regulator/rectifier. The oil on the floor is from a few too many screws being removed.
Since I had dug this far into the bike, I went ahead and removed the starter. It made it easier to access the back of the diode board. It turns out that I have the less desirable, sluggish Bosch starter instead of the newer Valeo model with gear reduction in it's drive train. The change was made in 1983, the year that my bike was manufactured. The starter seemed clean, i.e. no oil or grease in the nose and the nose bushing isn't worn excessively. The sluggish starter behavior is just the way it is with the Bosch unit and it will be upgraded at some point either with the Valeo or the aftermarket Nippon Denso model. The wiring to the starter was corroded and will be replaced with some of the O AWG arc welding cable that I have been using for battery cables.
To get to the starter, the battery and airbox need to be removed and this would be a good opportunity to dress out the wiring. Since I have the battery, airbox and mufflers removed, it will be trivial to pull the transmission enough to renew the grease on the input shaft of the transmission. Just a couple of bolts between the transmission and engine, the clutch cable and the rear swingarm pivots. I think that this is also a bi-annual maintenance item but since it's easy enough to do now, I may as well.
Just a few more of the removed parts and pieces from the bike. The scratches on the side of the tank are from the magnetic mount tank bag. Dirt collects between the flaps with the magnets and the tank.
There is a lot of dirt and grime caked onto everything and I've been toying with a way to clean some of it out. One of the disadvantages of a fairing as it hides all of those areas.
The new alternator is supposed to be delivered today. It's a long weekend so I'm expecting the rig to be back on the road next week! Probably sans cleaning…

airhead charging system
|Original Enduralast aftermarket|
On the Enduralast system, the rotor uses a permanent magnet so there are no slip rings or brushes and the stock problematic diode board and discrete voltage regulator is replaced with the integrated rectifier and voltage regulator. I have been wanting to upgrade to this system for a couple of years but it was hard to justify since the old system still works. I am still wondering if the addition of the larger battery and charging load contributed to the failure of the old system.

A humorous note in one of the research labs in the older part of the NARL facility in Barrow. The truth of the matter is most of the thermostats in that building are now non-functional. After someone had left the window open and turned the thermostat way down, the valves were changed to ignore the thermostat and just keep the room too hot. On Saturday, it was a fairly mild -9°F in Barrow with a slight wind.
I flew back home to Fairbanks on the Saturday morning flight and this is what I was greeted with. I'm thinking that I should've stayed in Barrow and enjoyed their balmy, coastal weather. It has been getting colder hour by hour throughout the weekend. I still haven't worked on the bike's charging system as the "heated" garage is pretty near freezing even with the heater fan running full blast. I think so much heat is lost each time the garage door is opened that it takes quite a while for the heater to catch up. The forecast is for much nicer temperatures throughout the week.
Maybe this is a good reason to return to Fairbanks. The sun actually appears above the horizon making the snowy landscape really bright. I took a walk this morning as it was too cold to take the sidecar rig out especially with a non-functional charging system. This is the view off our back deck looking south. You may notice a couple of moose tracks passing through the back yard.

I really liked the appearance of the clouds in this picture. This was taken about 3:15pm with some nice color on the horizon hinting that the sun was still around. The fuzziness in the clouds suggesting that there were still some wind higher up but it has died down somewhat. It was really feeling cold earlier with gusts up to 20mph and lots of blowing snow.

I'm up here to address a couple of network problems. Some things were moved or disconnected over the last couple of months and I'm starting to be concerned about the life of the metro wireless network.

Hopefully, it's just a blown out bulb but it could be voltage regulator, brushes or the rotor. The lack of charging was verified by the digital voltmeter. No problem riding home as there was plenty of battery capacity even with the heated gear turned on. The battery voltage was still 12.2v after the trip home. Odd that BMW chose the indication of a problem was the indicator not being lit.
Update Tuesday afternoon - Like every other iPhone app I've tried that works with Blogger, Blogsy for the iPhone is garbage as evidenced by Martha's comment. I believe that it isn't that no one knows how to write software but Google keeps changing the way they do things.

We had a nice visit with family and discovered a new place to stay called Maria's Creekside B&B. It just opened last August and is in a beautiful location and very nice rooms.
And finally a post without a single weather or temperature reference!
