My engine is an 89 small reed with 500 Fanatics HRD porting. The intake is a Honda 250r air filter without an air box. Stock ported intake boot with a stock cage and Boyesen reeds. Stock filter to carb tube. Exhaust is a Q V2.

Carb is stock other than the bore as far as I know. I am not aware of Q making any modification to metering circuits.
