I have been making some early dummy grips. Jim Lokai is planning on bringing his direct drives to Portland this year and all of them have been missing the left grip. The pics show my version of a reproduction. I tried to match those of an early G model.
Jim sent one of his twist grips to me for dimensions. I was pretty happy to see it as I had wondered how they worked. They always seemed to be stiff but actually have a tension ring that make them that way. Infinite cruise control!
I found some nice shrink tube that was sold as fishing pole grip (and other sport handles). It had virtually no shrinkage long ways and it only shrank on the diameter. I sent him enough grip material to do the right side on each bike as well.
So now he will have matching grips.

Here is what remains of a left grip on one of his bikes. So between the G model pics and this one I feel like I was on the right track

The mechanism looks interesting . And the spring is a simple but very nice touch .
But , those will never work . I mean look at the cross hatch ... not even close . LOL

Pretty cool. Always great to try to make similar parts to keep them looking like they did. I did not know what the earlier ones looked like.

Recently I was reading through some of my literature and read that it was believed this throttle may have been made by Villiers. So, I started searching and came up with this exploded view. Looks like a match! Then I noticed that they were used on Jawa motorcycles from 1934 to 1946 and maybe later. That site listed new ones for about $150.00. Slightly different.
