Ok thanks, yes they are drilled. How about the needle, and pilot? And does they elevation from 300 to 50 feet really matter in the change? It really sucks that my tuning has to be done 2.5 hour drive away. As I've mentioned I live in San Diego and if my bike's running for more than 30 seconds I get complaints. Very very gay. Thanks for the help. Is the drive up to Pismo worth it?
