Hi,
%HLQJ D IRUPHU FRS , FDQ FRQÀUP
some of the donut conspiracy
[mentioned in our Weekly Catch-Up]!
Very true, you just have a bite of
your food, then get called out to a
job and you have to leave it!
But on to donuts. When Krispy
Kreme opened at Liverpool, we used
to have one car drive out there to
pick some up while the other cars
covered for us. When we got there,
there were Police cars from
everywhere doing the same thing!
But really, McDonalds was the food
of choice, half price for police!

READY TO THROTTLE
Hi,
I am seeking help with problem with
my 1981 Kawasaki GPZ1100 B1.
This problem which will affect all
owners of this model eventually.
This problem will eventually affect
all owners on the B1 model. This
model was produced for one year
only with an analog type throttle valve
switch (throttle position sensor).
Kawasaki then changed over to a
digital system (B2) replacing the
throttle valve switch with a digital
potentiometer type.
The throttle valve switch (TVS) is
now obsolete. I have been in contact
with Kawasaki Japan but they are
unable to provide any information
on the system. The design was a
collaboration with JECS at the
time which is now part of the
Hitachi corporation.
I have searched the internet for ways
WRÀ[RUUHSODFHWKLVSDUW7KHUHDUH
a number of suggestions but they
all lack the details needed. There are
suggestions of alternate makes of
TVS but when I search for these they
are either later types or there is no
information on them.
I have purchased 2 second hand units
and neither of them work. The one
on the bike now is playing up. The
other alternatives are to replace with
a later digital system which involves
many component changes, converting
to carburettor which is getting away
from the originality of the bike which
is on historic registration.
I have started to dismantle the 2 TVS
units which is a slow process due to
them being encapsulated.
They are made up of a magnets, reed
switches, a single pole single throw
switch , 2 led lights and a couple of
other components. What I found on
both units is water ingress which has
affected the wire connections on the
circuit board. The loom entering
the TVS is not fully sealed and as
such it heats up during use and
sucks in moisture when it cools
through the loom.
I have the original Kawasaki
workshop manual which covers all the
models from the pre injection models
to the later B2 models. The circuit
diagrams for the B2 show the ECUconnections and lists what each wire
does. The B1 circuit diagram does
not show what the wires do. I have
KDGWKH(&8FKHFNHGRXWDQGÀ[HG
so I know this is working. The TVS
will not allow the motor to start if it
is faulty. An indication is if the LED
lights do not work then the motor
will not start.
Has anyone had to deal with this

anyway! – The BearMAKE IT LAST A WEEK
Peter,
Great job and the magazine keeps
hitting the right targets. Just had a
great bike week in Victoria book-
ended by the Blessing of the Bikes
at San Remo and then the MotoGP
a week later. Could be the start of
“bike week” tradition and wouldn’t
be a bad thing. Still surprises me that
even in the face of such great success
the trolls still get onto Facebook and
try and steal away the fun and gloss of
such events. As riders we are our own
worst enemies at times, we just need
to relax sometimes and appreciate
the efforts of others and the great
opportunity it gives us to share our
experiences as bikers and have a few
good times thrown in. Even the
local constabulary worked a good line
between fun and dangerous etc during
the week in my opinion. Marcel and
Sabine are to be congratulated on
their persistence to keep this going,
and all the volunteers working hard in
the background, and I for one hope it
continues to grow into a long-lasting
