Trading Out The 426 To A 450.. Got Some Questions

[oj250r]

ok i'm gonna end having to do a motor swap on my hybrid and my bike is already set up for a 426.... i'm gonna get a 450 next time it messes up and i was needing to know whats all different like with the oil lines and mounts.. are they same cause i think that they are

The lower middle motor mount is about .200 different. Depending on were you got your frame the tabs might be slotted to allow this swap.

Hey whats up. Go with an 03 YZ450f engine. The lower mount like posted is slightly off. The head stay mount is also lower but not by that much either.

Thank you
