... the Moki footprint is too big for the stock firewall.
That's the same impression I got from a quick look with the OS BGX the day the kit arrived. This engine also has a square jug; I think the slope of the cowl is a bit too "steep" to cover the top of the jug when the engine is side-mounted.
I'm looking forward to your photos.
