G 15 / N15

Hi All.
is the Matchless G80C frame good of G15CS or Norton N15?.
Thank you.

I believe they are different, being a single and not a twin.

If you are referring to the mid 60's G80CS frame vs the hybrid frames I think they are the same the difference being the engine mounting plates.

I have a complete G15 and a G80 frame, it looks like the engine mounts at the front are a little different but could easily be modified to fit, the rear section may be a little different in details like passenger footpeg and exhaust silencer mounts. Unfortunately the G15 is in the US and myself and the g80 frame are in Hong Kong, so I can't easily compare. I was going to turn the G80 frame into a G15 type replica using a Commando engine. I will try to find my spare rear engine plates and try a set of cases in the frame when I get time.

The front engine mounts in Nortons were a little different for the singles and for the twins,
for quite some decades even, so sounds quite likely.

Hi.
Please, the G80CS gearbox fixing plates are giod for G/N15?
Thank you

I would doubt it.

Engine plates for Norton ES2 (singles) and dommie twins were different - the shape and hole locations were rather different. AMC singles and Dommie twins crankcases are nothing like each other.

You - MIGHT - be able to cut and and weld and drill them enough to MAKE them fit.
But a bolt-on fit they will not be.
