Bump for a thread that is more that a year old.
The GasGas SM50 that I was talking about oh-so long ago is
now parked in my garage. It is time I started to learn all I can
about the bike. Most important... "Who made the MOTOR" what
model is it and where can I order some parts for it.
I think you all know what the SM looks like and I did not take any
pictures yet of the full bike, but, here is the motor.
"left side"
"Right side"
Along with trying to find some big bore kits. I would also like to find a larger
countershaft sprocket. The stock one is a 12 tooth and there looks like there
would be room for a 13 or 14 tooth.
I have a 2002 Derbi 50SM and the motors are definitely NOT the same.
I am pretty sure the GG 50SM is a Franco Morini motor. But, what model?
From what I could find. It looks very close to the Morini M65-C motor and not
the S-6 motor
Examples:

Morini also makes the S-6 motor with liquid cooling.
These motors, or derivatives of these motors have been used in the KTM and the
LEM model of mini-bikes. But which ones? 50cc or 65cc?
Some more research is going to be required. I'll let ya'all know more when
I find out. Plus I am open to suggestions and any information you can provide.
Thank you, Jeff
