Next was the engine. This is a fairly simple representation, as a good deal of it will be hidden behind the side covers and tanks. There were one or two misfits, but nothing disastrous. Unfortunately I didn't take any photos of it at that stage - you will have to read on a little further.
We come to the frame - this really was a disaster. The main part is a tubular structure, but problems arose even with the first section.
This shows the right-hand front tube assembled according to the alignment marks. The top two sections are in the plane of the rest of the tube, and angle towards the rear of the bike. In fact they should angle inwards toward the centreline of the bike, to fit into the single top member. The gluing land bearing the number 52 is facing straight outwards, instead of generally towards the rear, to receive the intermediate side tube. I redrew the mating ends to rotate the top section by about a right angle, to something which looked plausible.
Then it was possible to put together the rest of the frame, though in several places the gluing positions marked had to be ignored to get things to fit together. Then came the big problem - there was no way the engine would fit without significant distortion of the frame.
The left photo doesn't look too bad, though the casings on the left side of the engine project well beyond the footrest attached to the frame. The right-hand photo shows the distortion of the frame needed to get the engine in, and even then it wouldn't stand upright.
