Take the test

This one's making the rounds right now, but makes a very good point:

The sins of the previous owner

As many of you know, I reached the end of an 8-year search last spring when I finally found the right Kawasaki ZRX, and snatched it up into my stable. Since then, the past nine or ten months have been absolute coolness -- spiritual, even -- as my Z-Rex and I have become acquainted with one another. I'm proud to say, with much admitted bias, that I own one of the most fantastic motorcycles ever produced.

But there was always one small problem with my particular Rex that I could never solve. No matter what I did, achieving a suspension setup I was happy with constantly eluded me, sometimes almost mockingly it seemed. From front to back, top to bottom, I went through every possible suspension configuration you can imagine. Throughout the entire system, I made adjustment after adjustment in an attempt to dial-out a strange vagueness in the front-end feedback that I just didn't like. Now mind you, there wasn't really anything outrightly "wrong" with the way the Rex rode or handled. It was stable and responsive. But at the same time, it was never what I considered to be totally "right" -- and it certainly wasn't anywhere near what I felt convinced the bike was capable of. This is hard to explain, but the front felt heavy and "teetery" and low speeds, but overly light and dodgy at high speeds with a tendency to right itself. I was baffled.

So at one point late last summer, I basically gave up on dialing the bike in, resigning myself to the fact that it wasn't a full-on track bike like my ZX7R and ZX6R, and that it would never feel as perfect. It was a retro-style '80s hooligan bike, by golly, and I'd just have to live with mediocre handling.

Then, just last week -- as I began contemplating the possibility of biting the bullet completely and lowering my Rex to dragbike height -- I made a forehead-slapper of a discovery on the rear shocks that explained everything.

The tabs that hold the rear preload adjusters in place had been removed by the previous owner and the rings were being held by a set of secondary retainer castings higher up on the outer cylinder:

By my best measurement, this lowered the rear ride height somewhere between 15 and 20 millimeters. In and of itself, not an inherent problem. But get this, the previous owner left the front ride height in stock configuration!

"No wonder this thing handles like shit!" I literally yelled out.

So last night, after some rough calculations and experimenting, a friend and I lowered the Rex's triple clamps a total of 19 millimeters on the fork tubes. As soon as I rode the thing, I found what I had been missing handling-wise over the past year. The top-heavy, teetery feel is gone at low speeds, and the bike fires into turns willingly and without protest at speed.

Subsequently, I adjusted in a little more rebound force up front and will probably still make some changes to the front preload, but right now, it's like I bought a new bike. It's still no bullet train like my 7R, and I obviously lost some ground clearance and sacrificed the overall optimum geometry by going lower, but still -- it's literally twice as good as before.

The lesson: When buying used, don't assume the previous owner had any idea what he was doing. Go over everything with a fine-tooth comb and pour over the shop manual. If I had been more thorough in the beginning, I could've had this aggrivation licked a long time ago.

Spooky and beautiful: Shafter Lake ride report

For the first time in over ten years, I (along with some motorcycle pals and pal-ettes) rode out to Shafter Lake yesterday. It was a last-minute decision and I neglected to bring a camera, but luckily my good friend Rodger had his little digital “box” camera with him and we were able to take some simple snapshots.

Shafter Salt Lake is a huge Alkaline playa northwest of Andrews, Texas. Right now, it’s empty due to current near-drought conditions, but in this satellite image, it appears to be partially filled:

We took a wrong turn on the way there and ended up stopping for a few minutes to rest. Dig Rodger’s showroom-pristine 1986 GSX-R750. He also has a matching 1987 GSX-R1100 to go with it:

Soon thereafter, we were riding again and had crested the hill which leads into the playa’s basin. We stopped and parked at the observation point on the south side of the lake. With Rodger’s little camera, I took a series of pictures of the entire lake, which I composited together. This is a large image (2270x436).

Heather and Stephanie had never seen the lake before, and decided to walk down into the salt:

We knew better than to traipse through that stuff and decided to watch from the rim. Here’s Rodger saying something like, “Those girls don’t have the sense God gave raisins”:

Blane, me, and ‘Busa Dave contemplating the moment on a perfect West Texas day:

The girls in the salt:

We warned them about the harshness of the lake bed, but they didn’t care. When Heather returned, her shoes were ruined:

The bikes again:

There is a cemetery and native-American burial ground nearby. Here’s the marker:

All-in-all, a fantastic day of riding. It was a bit cool around the lake, but the ride home was warm and comfy. I got home around 6:30 and cleaned my bike until 7:30. After a little dinner, I was wiped out. There’s so sleep so sound as the one you have after a good, long motorcycle ride.

This land was your land

I'm not a big offroad motorcyclist, but this issue is important to me nonetheless. So should it be with you. Here's yet another case of the government telling the citizens how it's gonna be, instead of the other way around. Sure, this is about motorcycling on the surface. However, it is but one symptom of a much bigger problem:
