Engine Mount and First Trial Fitting

Started and finished the engine mount, and fitted it to the Ultimate to see how well it fits. The pictures tell more:-

Bags of room inside - Could've built a bigger engine

Exposed, showing the mount.

6mm dia. base, 8mm dia. spacers tapped M4 both ends

4 Degree angle

The original holes in the firewall are drilled at a 4 degree angle. This is to accommodate a large two stroke engine with a larger diameter cylinder and designed to fully enclose it so that unsightly holes don't need to be cut in the cowling. The KT120fsT needs to be horizontally mounted so the plate needed to be adapted.

Base is made from cast plate for lightness

So far it weighs 670 grammes including the mount, thats 1lb 7.5oz in old money. Not bad for a home build 24cc twin. There's a bit more to add, carburettor, manifold and delivery tubes, and exhaust pipes.
