Moose torque spacers

[hillclimberr]

I have seen moose torque spacers for mx 250's.I know they increase bottom end power but what would happen if you used two of them or made a thicker spacer. Would this give you incredible amounts of bottom end or destroy engine response

I tried one

on My 89 KX125 and it really made it run bad....
Killed the top end and did nothing for the bottom.
I think some bikes benefit while others suffer
