So far as I know, the H only came from the factory with 2 options on the starter switch. Original was mounted on the tank bracket and required reaching around the steering post with your toe to operate it, which was a pain in the a$$ as well as the knee, ankle, etc. There were a few aftermarket options to improve them with such as a lever, or such as ours with the little bracket and curved rod to make it easier to reach. I will get some pictures later today. Later models came with a bracket that mounted the starter switch on the left side of the steering column at a level it could be easily reached with your hand.
If you are not part of the solution,
you are part of the problem!!!
