CARB SPACERS

Mike, I ran a 1" open on my old setup which was similar to yours, wasn't impressed. The M1 sp with an open spacer will be soft on the launch, particularly with the little motor and foot braking it. Lots of plenum volume to get moving at lower rpms. I am going with a 4 hole to pick up some low end torque and improve the throttle response. Also switched to an Air-Gap this year. Guess we'll see!
