Many of you automobile-only people have never seen a right-angle tire valve stem. That part is normal, and are not completely uncommon on scooter tires. What isn't normal is where about 25% of the business end of the soft, brass valve stem appears to have been ground off with a Dremel tool. This caused a problem with the valve's structural integrity, making Jeff ride a few miles at very low speed to an air compressor that costs $1.00 to use, and was very nearly useless in getting atmospheric pressure into said tire due to said valve stem.
Finally getting enough air into the tire to ride safely across town on it, I headed to the shop to open it today. Rooster had the day off, but we spoke on the phone, and he had to admit that the 90° valve stem was probably a bad call on his part -- he recently changed my rear tire, you might recall. Yes, it probably rubbed the reduction gear casing, causing what you see, above.
So, I'm riding the boss's Demon Buddy until Tuesday.
It is a wikkid bitch of a fish.
And Tara and Tonya brought me Cuban guava cake bars!

Meet Ruk
Ruk may be the second pony in FastCat's stable, shortly.
More tonight.
UPDATE: Here's another photo.
UPDATE: Yep, it's mine, now. OMG, what have I done?

Holy MPG, Batman!

As a waypoint, my highest recorded mileage before today was 66.1MPG.
Regardless, I'll take 63.11MPG average since the repair.
UPDATE: 9/3, 7th fill-up, 64.6MPG last tank. New average, post-repairs is now 63.33MPG.

Still Fiddlin'

I'm not sure it's been started since then. Still, without this woman, I'd be going nowhere. Can't even afford bus fare, anymore.

Cucumber Slumber

STILL with the overheating!
The process: Burp the air out of the system, fill with antifreeze/distilled water. Do once every 14 days, unless I ride at 50mph or higher. Then, do it more often. I now have only 4 of the 10 screws in the front cowl so I can do this quicker.
I really think I have a bad head gasket, which is a shame, given that we did a warranty repair on this, one year ago (just weeks before the warranty expired). Now, here's the funny part.
The gasket they sent last year, the mechanic showed it to me. It was a tan, cardboard-lookin' affair, with a couple of smears of Permatex in the areas where I had determined the gasket had failed (given where the oil leak was). He theorized that they added the Permatex because they had likely determined this was a weak point in the overall design, and wanted to insure that the gasket sealed better than the factory-installed one (and didn't want to leave it to the mechanic to know where to apply it).
My new gasket arrived today (ordered because I've been bartering a bit with the shop for work). It is NOT cardboard. It is black, and appears to be some type of synthetic material, or perhaps metal...! And it is two-layered, and has what appears to be two brass grommets holding the two layers together. Could they have further determined that the gasket they sent last year was also somehow inadequate, hence the change...? Or [fill in the blank]...?
Keep in mind, this year, there's no oil leak, but air/gases are getting into the cooling system, and IT doesn't seem to be leaking anywhere, either (gasses/coolant filling the reserve tank and outgassing from there might explain that), so this breach seems to be between the cylinder and the water jacket, as best I can tell. Thankfully, the bike still runs great, and other than it occasionally hitting the high temp mark, there are no other symptoms...

Another Heat-Related Issue

That's all I can figure. SYMPTOM: On hot days, after 15-20 minutes of riding, engine wants to sputter and die at a stop. Can be remedied by keeping an inordinate amount of throttle on while braking, or... after first noticing the issue, pop open the fuel filler, restart (with a healthy goose of the throttle!), and ride on, like nothing ever happened. During the latter, the problem does not reoccur.
The section I circled in yellow, above, looks to me like some sort of venting system. If anyone knows, sing out -- I'll try running a bit of guitar string through there, to see if some gunk is clogging that up, tomorrow. As you can see, the bike isn't surgical theater-clean. ;)

Closer to Cucumber

LOTS of air came out. I added the coolant that the air had displaced. After a while, the scooter got hot enough to want to start splashing coolant out, so I shut it off, waited a few minutes, and repeated the process.
The ride home: Generally, the temp gauge stayed in the low-to-midrange, but did occasionally go quite high, even hitting full "hot" once for a couple of seconds. So, I think there's still air in there.
If I have another bad head gasket after only nine months, I may go postal.

Cucumber? Not Quite Yet.

The whole overheating issue has been vexing me this month. I've been cautiously riding, pulling over and shutting it off whenever the gauge stayed at full-on HOT for more than a couple of minutes. Granted, most of my rides are 1-3 miles, so this hasn't been much of an issue... but on rides to the shop (~10 miles), I've had to stop midway, and sit for 15 minutes or so before continuing.
The symptoms pointed towards a bad thermostat -- one that would barely open at all. Replacing the thermostat today seemed at first to resolve the issue, but then I decided to really put it to the test. After five miles of issue-free riding, I hit the interstate. After a few minutes, I was again at full-on HOT, and pulled to the shoulder to let it cool, have a cigarette, and contemplate my next move.
UPDATE: Rode back into East Nashville for Josh Matthews's gig @ Drifters and back, tonight, using only surface roads (45mph, max), and only touched full-on HOT a couple of times for a few seconds... so something has improved, it would seem. I'm thinking there's air in the system. Will look into that tomorrow, since I have to pull the cowl back off anyway -- dumbass me forgot to plug the front turn indicators back in, today).

Snow Scootin'
Through some roundabout circumstances which included my doing some web site design for the shop's mechanic, I ended up getting a new rear tire (Kenda, OEM) for BRU.
Looks like I needed it, hm? Got over 14,000km on that bad boy, but it should have gone at 11,000km.
Even the new tire won't help me the next few days, though...
Can you believe that a couple of hours ago, there wasn't a flake of snow on that seat? Now, I know... that's not a lot of snow. But this is Nashville, people. In the 14 years I've lived here, this much or more accumulation has only happened like three times.
Here I am, arriving at ESS this past Wednesday for "Project X." More about that as time goes by.

Christmas Caliper (Non-) Catastrophe
It was an unseasonably warm 56°F when I set out to run some errands on Tuesday. I noticed I was low on gas, so I set out for a quick run to the Lewis Country Store in Scottsboro before swooping back into town for a stop at the public library and Aldi.
Just as I finished the 55-70mph ride up Briley Parkway and Ashland City Highway, and pulled into the gas station, the rear tire locked up as I was slowing towards the pump. "Uh-oh... is that my belt coming apart, jamming in the clutch?" Being thankful that I have my cellphone Just In Case, I give it a little gas. It lurches about 6" forward, and stops, again, bucking like a horse. I get off it... can't even push it.
Closer examination shows that the front bolt that holds the rear caliper to the swingarm has vibrated itself completely loose. If not for the muffler, it would have hit the road some time ago, but as it is, it backs out only as far as the muffler will allow. That distance, however, is sufficient to allow the caliper to clear the threaded end of the bolt (probably designed that way so one can change the rear brake pads without removing the muffler, if one is talented enough).
The end result being that the caliper, now only being held by one bolt, was allowed to pivot on the axis of that bolt, and that last application of the rear brake was enough to cause the front of the caliper body to contact the rotor, which cut into the caliper like a saw blade. Good thing I wasn't going very fast, eh?
As you can see, the end of the caliper where the damage is is now discolored to a bronze-like color, instead of the aluminum color of the rest of it. I hope this does not mean that it is irretrievably damaged. The rotor only has some small nicks in the very edge, and no burrs, so I think it is okay.
The whole caliper, uninstalled. I couldn't get the small wrench I had with me into the tight space to re-tighten the front bolt, and I wasn't going to try to remove the muffler there at the gas station. So I removed the caliper from the rotor, and hung it over my rear passenger footpeg to get it home (it definitely would not have been safe to leave it attached as it was). Today, when I needed to ride again, I removed the caliper, entirely, to prevent further damage to it or the brake line.
UPDATE: Now that I think about it, I wonder if this hadn't been going on for some time, and it only getting burred enough to catch when I noticed it. Look at my mileage chart at Fuelly. If this had started between 11/11-11/15, that would make some sense, wouldn't it?
