can the pm 55 fit sr 125 ?

has anyone tryed to fit the pm 55 to the sr 125 ?

i know the fan cover will need to be modded
and maybe play about with the sr mount
but can it squeeze on ?

allso is it worth me buying the big bore stub as its the same price as standard and opening my 172 port ??

any real gains in this ?

 

The fan should not be modded as you say, make the pipe fit round the cowling.
