Hello,
I Am Darren and i own a 1979 Yamaha yz250.
I have the original 250 engine with correct Numbers but the engine is broken and almost unfixeble...
So i can buy a complete Yamaha yz125 engine (1987)for €375 euro’s and i am considering to put this engine on my yz250,
I think the 125 is faster then the 250 beqause Its LC and younger
