In!

Grabbed the motor with both hands and heaved it over to the frame, which was strapped down to my makeshift bike stand. Slotted it into place without too much difficulty and slipped some mounting bolts into place. I don't know how long the engine and frame have been apart, but it certainly seemed pleased to be back in its rightful place.

Head, Part II

Checked the height of the pushrod tubes with the head placed on the cylinders, and worked out the correct thickness of translucent seals (bottom) and o-ring (top) to seat properly. With these seals in place the head was between 1-1.5mm off the gasket, and this closed up nicely when the head bolts were tightened.

Hubs

Picked up the hubs from the powder coaters. What a difference! Fitted new wheel bearings so all I need to do now is teach myself wheelbuilding....

Head

Fitted new valves and springs to the head. In the kitchen.

Frame

Started frame assembly. Even just this first step makes it look recognisably like a bike.

Back in Black...

Frame parts back from powdercoating. The fasteners needed to screw this lot back together have been zinc-plated, so it'll all look pretty fresh when it's assembled.
