Yes but not all. The starter is situated where the dynamo was originally placed and drives a gear at the rear of the clutch. I believe this is the ideal position as it allows the use of a pre-engaged or Bendix type starter. However, Ernst will not fit these to original crankcases as it requires some machining to make space behind the clutch. He makes his own new crankcases. The down side of this position for the starter is that one needs to find another place for a charging system and Ernst does this by producing a combined charging and ignition system to be placed where the original magneto was placed. It seems to work well but is noticeable. My understanding is that Ernst does not speak any English but if you meet him then another English speaking German person, possibly Little Honda, helps with communication. I do not have any details of what make or model of starter is used but it is robust and works well.
