    See if you get enough cable travel to make the closed to fully-open transition. I expect it's probably about an inch & a half, look & see.

    Since we're having a twist-grip conversation, who is attributed the invention of the motorcycle twist grip? Hint: was also the fastest man on land and in the air before World War 1! For the land speed record portion he rode a bevel final Drive V8 engine motorcycle engine of his own design and manufacture.




    Answer Glenn Curtiss of Hammondsport New York. There is a very interesting Museum there if you get a chance to see it you should.

    Anyone who rides any Indian Motorcycle of a certain vintage will be familiar with the left-hand twist grip as that's what they used to vary spark advance.

    Hey John, sorry for the late reply, I haven't been on this forum much lately.
    Happy to hear that you like the conversion. It is a fun mod and it doesn't hurt that it's low tech, simple and easily reversible.
