Subluncay I don't think u know what your talking about half the time.

Get ahold of Carl bud aka iceracer.

My cylinder is heavily ported and the stock 34mm carb was just fine man.

 your missing out on some power maybe. raising the exhaust port makes the pipe peak earlier because of increased blowdown. widening the exhaust port makes a bit more torque and optimises for larger carbs to make torque.

porting the transfers gets tricky because it could lower the primary compression wich would lower the torque and increase the blowdown


milling the head to get a good squish and compression is as responsible for a modern running engine as the ports.
