Is there a performance gain for port'n polishing the head of of a 400ex with a pipe , filter and bored out carb w/ out choke.
someone told me to this, when i had just a slip on, they said to get a full exhaust and port and polish the head and you will get good gains with the port and polish, and he said i needed the head pipe to let more air out.
is this true cause i got the full exhaust, or do you need anything else to for this to work?
