of Barkbusters and brakes...

   I *finally* got around to re-installing my barkbusters today. I got
most of the black paint off the one DJ sent me (so it'd match my bare
aluminum version), and DJ's bend was pretty close to what I needed.
Then I trimmed the end of the anchor scrape had provided in NC so that
the guard would sit flush with the bar end (he uses some exotic guards
with unique bar-end clamps). Satisfied with that work, I moved on to
the rear brake.

   At Brushy Mountain last summer I talked Mr. Cook into taking a spin
on the RM. He complained twice of the rear (drum) brake sticking, and
as soon as he said it the first time I realized he was right because
the thing was acting odd earlier. When we switched back I
intentionally abused the rear brake to try and judge the degree of the
problem. It was definitely sticking.

   Fortunately, and since I was having a lot of trouble using the RM's
clutch with my broken ring finger by this time, Jim arranged for me to
ride his 300 the next day (I believe he rode RaRa's extra bike). So
today I finally decided to investigate (in hopes of maybe getting to
ride one weekend soon!). I was thinking maybe the spreader shaft was
so worn (it is a 22 year old bike, after all) that it was getting
completely horizontal between the brake shoes... thus sticking them
fully expanded. Jim suggested it might be something much more simple
like some grit and grime stuck along the shaft somewhere and
preventing smooth operation.

   Well, it turns out it was even more simple than that. The brake
shaft arm has a sort of coil [return] spring with one end wrapping
around the brake arm and the other end bent to insert into a hole in
the brake shoe hub. The spring had come out of the hole, unsprung, and
was totally useless. Re-inserting it (no small task) resulted in
non-sticking brakes. :-)

Can't remember which I had extras of, but they were either Acerbis
or Cycra.  Or maybe Moose.  The Acerbis have a raised area that
corresponds with a groove on the guard that adds a little more
incentive for them not to turn.

We went back out to Brushy yesterday and I had three people
looking for your tree, but came up empty handed.

Go fast and aim for where the trees aren't.

    Seems like it'd be easy enough to find, but I just looked over the
trail map and can't remember which loop that was. I know it was the
loop we rode on Saturday and that it was a fairly high speed loop that
we'd already completed once before my OTE. The loop ran
counter-clockwise. The tree[s] would've been on the south portion of
the loop. I know for certain that there's a big dip right before the
tree... a smooth drop of maybe eight feet or so followed by a smooth
rise of 8-12'. The tree[s] should be just past the apex of the latter
and off to the left.

    Look at the map, and the direction arrows, I suspect it had to be
the 1B/2B loop. And if so, the tree[s] should be somewhere near the
"2B" text on the trail map. Now go back this weekend and look again!

I definitely remember the terrain, just not the exact trail,
apparently.

Chances are that I'm not riding for a while, personally.

How come? Are the gaping holes in your leg causing you problems?
