R50X engine number?

[MikkelR]

Hello guys! I got a TGB R50X 2010 model where i am going to swap engine. Trying to find the engine number, but cant seem to find it. Anyone know what type of engine that fits, or have an original engine number? Thanks

never swapped a TGB motor out-- but have
swapped a 50cc out a jog motor for a 90cc (FYI most scooters have jog/minarelli motors)
both rear wheel & tranny splines have to match and wheel size is very critical so that your not rubbing the frame.
back near the rear wheel on the motor  there is a flat spot with the serial(vin) number
look from behind the rear wheel
 what are you trying to slip into the frame?
