what size Mikuni to Run on GP292


carbs

too big can be a problem with responce..... I had 44mm round on mine that was running 54hp on 112 octaine. Down sized to 38mm and seems to be runnning just as strong. I have a original 50mm kehin from a thunderjet that I had ran on the dyno after the motor was built. It actually produced 6hp less!
 
44 round
