Hi, i got sent a cylinder for my '97 yz250 which i bought over the net. When i recieved it is noticed that the manifold and powervalve cover was different to my '97 barrel. I found in my manual that it looks like it came off a '94 yz250 cylinder. I was wondering if anyone knew whether a '94 barrel would fit my '97 250. I know i might have to buy a different pipe but whether the ports would work. :bang:
