Hi there all, Happy new year and all that..........Just wondered if anyone has any descent pictures and any other useful info about running a pre engagement type starter like the RTV's had years ago. This uses a external tooth ring gear mounted on the back side of the chain wheel, and the starter pinion would mesh from the lower behind. I know it would require some machining to the crank case, I am not worried about that as the cases I will be using are new ones not originals. The RTV cases had a depression cast into the lower rear of the gearbox housing to accommodate the starter, i will not have that luxury, but there are many styles and types of 12 volt starter available now verses years ago. I only ask as the engine will be larger in capacity and I would be concerned about the longevity of a Grosset one in this case........this is also my engine so I can do to it as I please. It is the centerpiece for my next twin project bike based entirely on the twin racer I built a few years back, with all the suspension upgrades plus much more.........I am leaning towards not running any kickstart at all, so the electric starter needs to function like a modern bike, and my right knee is not so great after our accident back in 2015. Interested to see what we come up with on this one...........Cheers......... Greg.
