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.
