What chain did you lot use?
Or... Does anyone have a Knakered chain I can nab as all I need it for is to align the engine/drive sprocket to the rear wheel/sprocket.

If anyone's already got engine spacer measurements, I'd be interested in having a look.

I forget. It's a 23 with f1 engine or something less obvious?

The bottom ends of those two engines are basically the same, they should line up like magic.

Nc23 frame with a F2 (1992) lump...
I took out a F1 sleazed lump that had no engine spacers! One of the many odd things I have found with the "story" I got from the prev owner!
