Introduction, new member

New member, and just wanted to say hi and introduce
myself.
Jeff from So. Cal. USA.
The reason for joining this forum is to find out information
on what I believe is the Franco Morini M65C competition motor.
I have a 2002 GasGas 50SM Rookie. So far I can not find anyone
that knows about the motor that GasGas used in this bike.
It is also very similar to the motor that GasGas used in their
70cc Trials bike. The TXT70 Rookie.
The SuperMotard bike has a alloy cylinder, but, the trials
bikes use a iron cylinder. One is 49cc and the other is 72cc.
The case bottom ends look the same. with the exception of
the 50SM having an oil injection system and the TXT being
pre-mix.
If indeed the GasGas used the Morini M65C motor.
I would like to find out if there is an aftermarket 70cc - 80cc
alloy kit for these motors. & Where I could purchase one.
My next thought would be an Expansion chamber. As I suspect
the stock 50cc pipe would not work the best on a 70-80cc top
end.
I can post pictures or links to pictures of the GasGas motors
if you think that might make identification easier.
Thank you for your thoughts.
Jeff

Ok, how about a couple of pictures to spark some debate.
Right side GasGas EC50Sm

Left side GG EC50SM

And for comparison. The left side of a GasGas TXT70 Rookie.

What do ya' think? Are these Franco Morini M65-C engines?
