Hi everyone.

does anyone know whether the bore from an 04 WR450 would fit onto my WR426 engine and cylinder with the appropriate piston. might have a 450 bore in condition to play around with and i was just curious as to whether this would work.

It is my understanding that the '03-'05 450 cylinder (or an '06 WR450) will fit the engine, but the 426 head can't be used with it. You'd need a a 450 head of the same year/generation to make it work. Overall, I don't think the 5% increase in displacement would be worthwhile.
