Question regarding Hirth Motors

[John Boucher]

I had a chat to Donald. Waiting for CAA to issue atf for Jora with 85hp engine. All technical purposes, it's a 3702. The torque is actually higher on 85hp engine than on 100hp version. Installation is a mere 5kg more than a 582 & it kicks arse! This setup will be comparible to a 912s if not better and at a serious weight, performance and price advantage!
