200m engine swap on a 125m chassis

[punkrokr1701]

Is it possible to put to 200m engine unto the 125m? seems like just connecting the drive chain, electrical etc etc,

[ebecme01]

maybe in the 86 125m chassis, i would say no for the earlier models

The bottom ends on the two engines are totally different, and the 200 series engines are vertical cylinders, while the 90 to 125's are laid down. It would take nothing short of a master fabber to relocate the cylinder to the front of the case in order to use it in the 125 chassis (it's been done with a 200X engine and a 250R engine to date)
