Hi,

The 38mm carb will bring a little bit more low-end torque and a little less top-speed (good for a trike!)

You adjusted the intake-port to the cross-section of the carb and the holes will bring a better turbulence - absolutely right!

Stephan_S asked if you also reduced the exhaust side (if yes, why?)
qoute: I also worked over the exhaust side

Hope you are fine after that night-warmer
