Z602 is now rated to 3600rpm

[Westro]

I see that Kubota Motor's web page has a 3600 RPM rated motor vs the 3200 RPM rated version that is in my BX1500.

I have already pulled the governor back to give me the 3600 RPMs in my BX, but it has some vibration up there. Any idea on what they would be doing with the 3600 RPM motor that my 3200 RPM motor doesn't have to help the vibration?

Thanks
