Repairing the
Damage Updating the
outdated LET'S
PLAY TWISTER! Well,
well, the deep freeze is upon us. There is no denying it
now. All hope is gone. We'll have no decent riding weather
until April or maybe June, if next spring goes anything like
the last one. But don't forget about the machine that gives
you the grins all summer. Now is the time to be giving it
some attention to prepare for the many miles to come next
year. What to do? What
to do?... If you are a hard core rider (ten thousand miles
or better per season), your bike has been telling you in its
own little ways. "What to do" is more like "when to do
it." This year, I
managed to log about six thousand miles on my ZX-11. These
are considerably fewer than my usual, but they were brutal
miles. I rode this thing as hard as I could and as often as
time would permit. It is time to pay the piper. Due to a little
low-speed mishap involving antifreeze, the road and a
locked-up front tire, I need a wee bit of body work and a
paint job. As long as I'm at it, I may as well powder coat
the frame and swing arm and change my standard
white-on-black gauges to black-on-white like the cool,
Euro-bikes. Neat-o. I located a gauge guy who is fairly sure
he is up to the job. As long as the
thing is in a zillion pieces, I think I'll rebuild the forks
installing new springs and better valving. An Ohlins rear
shock is also the subject of deep thoughts. Brakes are a good
thing. Better brakes are a really good thing. The summer of
torment left its mark on the ZX's brakes. Aggressive sport
riding and drag racing have turned the front rotors into
warped scrap metal. They must be tossed. Aftermarket cast
iron rotors are the best choice. They have exceptional
stopping power and are nearly impossible to warp. At about
$500.00 for the set, they are not cheap, but they are really
not too much more than factory parts. This is, of
course, a tad more than I really planned on doing this
winter, but, oooh, I'll have a practically new bike this
spring! Okay, enough
gibberish about my ordeals. Let's go over something you can
and probably should do this winter. Factory brake lines on
nearly every bike made just plain suck. Rubber lines are
soft and spongy--ick. The older these lines get, the mushier
they become. Give that old KZ1000's lever a squeeze and see
what I mean. They gotta go. Stainless steel braided lines
end the mushiness forever. Aftermarket lines
are available for many bikes, especially Harleys and sport
bikes. Check your local shop for lines that fit your model.
If nothing is available, you can have stainless lines custom
made. Midwest Cycle Supply is the one spot in town that does
this. If you plan to
install these yourself, use a brake bleeder or vacuum pump
to drain the brake system of as much fluid as possible
before you disassemble the works. This will minimize the
chance of fluid spills. Brake fluid is very corrosive and
will ruin paint in a speedy manner. If you are going
the custom made route, you will need to bring your old brake
lines into the shop to be copied in braided stainless.
Measurements alone will not do. Stainless lines are stiff
and will scarcely flex or twist. The fittings must be
installed perfectly, or the new lines may fit poorly and
bind. To get the best fit possible, bring your machine into
the shop and have the new lines laid in next to the old ones
on the bike. You do have some
choices in new brake lines: plain braided stainless or vinyl
or plastic coated braided stainless. Raw, uncovered
stainless braid looks pretty cool, but if it rubs against
anything, it will saw right through it. Coated braid solves
this problem and gives you a choice of colors. I chose black
for my ZX. They look nice and won't hacksaw spendy body
work. Installing the
goods is as easy as disassembly. Use new crush washers on
the fittings and don't over-tighten the bolts. A
stripped-out caliper is no fun. Brake bleeding is
a bit more difficult. A vacuum pump or power bleeder will
make this task much easier and save you lots-o-time. If you
don't have access to such an animal, plan to spend and hour
or two and do it the old-fashioned way. Attach a piece of
aquarium air line or other clear tubing to the bleeder valve
on the caliper. Drop the other end into a can or jar. You
will be able to see any air bubbles coming out of the lines
in the tubing. Fill the reservoir or master cylinder with
the correct brake fluid for your bike; pump the lever a
bunch; hold the lever, and crack open the bleeder valve.
Don't release the lever until you retighten the bleeder
valve. Keep the reservoir full and covered, or it may squirt
fluid in your face. Repeat this whole process until you
achieve a good brake feel and no more air comes out of the
bleeder. If you are a
Twister® champion, you can accomplish this all by your
lonesome. If you can't even touch your toes or you have a
chopper with an eight foot fork, get a buddy to help. Be
prepared to buy beers, because this may take a while. Be
patient! This little
project will cost about $35.00 per line if you install them
yourself. Installation at a shop will cost about $40.00 per
line. Your brakes will
be much better, but be careful on your first ride next
spring. Don't grab a huge handful of brakes and go sailing
over the handlebars! Take it easy, and get used to them.
I have work to do,
and, now, so do you. I'll keep you up to date on my project.
Don't freeze to death. See ya. -Doc M.M.M.
