650 vs 701 factory pipe manifolds, same or different?

[yamijumpn]

anyone know if the factory pipe manifold for the 650 is the same as the 701 (61x) minus the mounting holes being slightly smaller than that on the 62t

the original 650 factory pipe manifolds have square ports that match the 650 cyl ports. the 61x is shaped different. the 62t cyl ports are shaped the same as the 61x but they are bigger. i requested a 62t manifold when i bought a new B pipe. i know the bolt holes were for the 10mm instead of the 8mm but it didnt look like they opened the ports up for the 62t. its been a few years since i had that 62t manifold in my hands.both the 650 and 61x 701 manifolds have the 8mm holes unless somebody hogged them out.

I run one on my blaster with a 62t bottom 61x top end. I had it port matched and opened up to 49mm it rips has factory limited pipe. I couldn't tell any difference,just have it opened up and you will be fine
