I had forgotten my first experience with my N15.
To fit the engine into the frame is a nightmare, the two lower engine fastners are accross the frame tubes.
But after a kamasutra positions the engine is in place now with gearbox.
I thought after have rebuilt my P11 nothing could be so hard but fit the G/N15 in place is more difficult.
Sorry i cannot post pictures.

The left engine/gearbox plate doesnt have the hole for the inner chaincase spacer.

The very early hybrids (N15CS, G15P) didn't have the stud for the inner chain-case. This was an oversight by the factory, as noted by Paul Morin in his essay on the hybrids, and was soon rectified in one of the next batches. Obviously you've got one of those early bikes, or at least an engine plate from one. You need to drill the left engine plate, otherwise the inner chain-case will start to rattle and crack. Those 3 tiny screws holding the chain-case to the crankcase are not up to the task of carrying weight of the complete primary chain-case. Use one of the later engine plates as a template when drilling the hole.
