YS .60 SR HELP! with specs please
Hi
I am looking to power a gp revolver with a hot 60-90 sized 2stroke. I have been offered an unused YS .60 sr but cannot find any spes on it. do they make good power and revs with a pipe ? what do they weigh ? any help on this engine would be really appreciated as I cannot afford a JET 60 or 90.
thanks
