    Industrial engine conversion. *Private* group.

    I've recently been thinking about oil cooled heads for these. Might not offer as much cooling as water and need the use of a second oil cooler radiator. Anyone have any thoughts on whether the stock pump would be able to supply the extra volume and maintain pressure?

    Aeromarine 60hp V-Twin Engine

    Just watched the video on the valley assembly. Seems pretty simile. The balls are just a spring for the idler pulley. Bit of pre-load setting it up to stop the belt slipping. Then as the tension on the belt changes as the engine runs it allows the change in load to be damped by the springs...

    72kg and 90hp. Seem to gave a selection of redrive available. I have no idea what is in the housings. Plus it's rotax money before shipping a duties.

    Will add that Kevin still deserves credit for bringing the smaller engine to a wider audience and his personal testing.

    The gk engine with a redrive for use in drones has been around for a while from a company called subaruair air in china. Only seem to have a presence on alibaba. They use the 1000cc version.
