Homemade Throttle Lock

The idea is just like taking one of those little wire tie twisties that
close a bread bag. Right now, imagine that you are closing
the bag of bread. You have gathered up the bag and twist the
wire and plastic tie to close the bag.
Now imagine that instead of twisting it a couple times, you twist the
two ends until you reach their ends. Now you have a closed
bag of bread with the wire tie, but the ends have been twisted together
and the little pig-tail is about an inch or two long.
Now imagine taking a wire twist tie about a foot long and doing the
same thing to close the bread, but now the little pig tail is about 6
inches long. It is still twisted, one wire with the other for
the full 6 inches.
Now imagine, putting a tie like that on the throttle grip of your
bike. Put it on up near the starter button, but still on the
throttle grip. Don't put it in the crack between the grip and
the block that the mirror attaches to.
Put it on tight enough so that it does not want to slip easily around
the throttle grip.
Now imagine replacing the wire tie with a much heavier tie, like a bike
spoke a mm thick. The spoke is much stiffer, so instead of
just twisting the wires with your hands, you need a pair of pliers or
vise grips to twist the ends together.... But you do get them
twisted and while it is fairly tight on the throttle grip, you can
still push the ends of the wire ties and make the loop around the
throttle grip move.
Now, arrange the pigtail so that it points straight up toward the
sky. Put your hand on the throttle grip and using
your index finger, push the pigtail forward until it touches the brake
lever. (Call this position #1.) It stays right there, and
when you roll on the throttle, the pigtail lifts right off the brake
lever, not interfering with normal throttle motions at all.
Now imagine rolling on the throttle to a mid range setting.
With the throttle rolled on, push the pigtail forward again.
When you release the throttle grip, it tries to roll back closed
(forward) but the pigtail is stopped by the brake lever. It
supports the throttle grip so that the throttle stays open. (Call this
position #2 - the rest position.)
If you manually roll the throttle closed (forward), the brake lever
comes into contact with the pig tail and the whole wire tie slips on
the throttle grip so that the throttle closes and the pig tail is now
in position number one again.
While the throttle pig tail is adjusted to position #2, the throttle
stays open to the setting selected when pushing the pigtail forward
during normal cruise. You can let go of the throttle grip and
the bike will still continue with an open throttle. If a
little more throttle is needed to go up a hill, all you need to do is
roll on a little more throttle. When the hill is mounted, The
pig tail will support the throttle at the previous position.
Well, I don't know if that gets through to a few more readers, and I
will be posting the picture, but this description will need to do for
now.
