Hey Guy's, I have come across a couple of head & barrels to suit RM125, either A,B or C BUT the strange thing I find is, firstly the barrel has a T shped exhaust port (where the stock A,B,C is square) and an 'un bridged' intake port, unlike all other RM125 A, B orC's I have ever seen.
Secondly, the cylinder heads have a factory squish-band !!!!
What could these be off?!!
I'll get a couple of pics soon.
