It looks like a Hula-Hoop that broke in half.
THE SAUSAGE-SHAPED TUBE
Since Jody is the same age as my vintage bike,
I wonder if he remembers the horseshoe-shaped
inner tube that the SoCal racers used in the 1970s
so they could change the tube without taking the
Jody raced with a Time Saver tube at
Saddleback, Carlsbad and Indian Dunes in 1977.
It was invented by a guy named Claude Maynard
who owned a shop in Blythe, California, and was
licensed by Cheng Shin Rubber Company. It was
basically a regular motorcycle tube that looked like
it had been cut in half with the ends vulcanized
closed. If you laid it on the ground and inflated it,
it would look like a 4-foot-long sausage, but when
you put it inside a tire, the air pressure would push
the two cut-off ends together, forming a round
tube. The benefit of the Time Saver was that you
didn’t have to remove the rear wheel from your
bike to fix a flat; you just laid the bike on its side,
popped the bead with tire irons, cut the old tube
with a knife to get it out and then stuffed the Time
Saver tube into the wheel and closed the tire up.
However, we should correct you on two things.
First, Time Saver tubes were not popular with
SoCal racers in the 1970s; they never caught on.
Second, Jody is only the same age as your vintage
bike if you own a Brough Superior.
Doctor Frankenstein would be proud of these stitches. They
will keep this old fender alive for another ride.
BRIDE OF FRANKENSTEIN
Let me start this letter by saying that I don’t have a
lot of money to spend on my motorcycle. I worked to
buy a used 2010 KTM 150SX, and it’s all I can do to
keep it running. So, imagine my dismay when I looped
out and tore the rear fender. My dealer says that a
new rear fender will cost about $70. I tried to fix it
with duct tape, but it didn’t work. Isn’t there some
kind of glue or adhesive that will make my old fender
Unfortunately, the 2010 KTM rear fender was molded
to include both the side number plates and rear fender into one unit. This raised the cost and complexity
of the part. The best fix, until you can afford a new
rear fender, is called the “Frankenstein stitch.” All it
requires is a drill and some safety wire. The first step
is to drill “stop holes” at the ends of the crack. These
small round holes will stop the crack from spreading.
The second step is to drill small holes directly across
from each other down the length of the crack. Finally,
thread the safety wire through the opposing holes and
twist it tight. It’s not attractive, but it is workable. On
a side note, last week the front number plate of our
2017 KTM 350SXF got hit by a big rock mixed in with
some roost. The front number plate split in half. We
also tried taping it together, but, just as in your case,
that failed. Finally, a carpenter friend of ours came
down from the next pit with some Tek screws. He
overlapped the two halves and screwed them together.
Also not attractive, but good enough to protect the
electronics behind the front number plate. You gotta do
what you gotta do.
