Saw this today when I went to buy a spare side shift transmission. Flat 4 alfa romeo engine in a Puma... belt drive overhead cams. Owner said 1.5 litre engine about 100 hp.

He also had a tail shift trans for sale if anyone wants one in the Hamilton Ontario area. wants $300 Canadian, will have to pick up between Branford and Caledonia. Old german guy had 2 pumas, 5 BMW bikes and a 300TD Merc that looked immaculate. Figures at 80 it's time to move some stuff. Lots of alfa engines on the shelf too. If anyone wants the trans I'll pass on a name and phone numer, found the ad for the trans on kijiji.
