A New Engine

The first dyno session did not go so well - The engine eventually ran several of its bearings, probably caused by corrosion on the crank. Luckily Mick noticed the slight power drop and stopped the engine before it completely destroyed itself by throwing a con rod.

So it was engine out and re-build time.

Aside from damaging the bearings and con rods, the crank shaft was also bent and a replacement crank was sourced from another engine.
