need help badly....
 

what is the equivelent (air flow) for the k&n air filter...the bmc standard version or bmc race version

Don't know the equivalent, but I know the BMC race has very little filter material and really isn't good for the motor if you put a lot of miles on it. You're better off going with the street.

actually your the person i wanted to ask...you posted a reply to one of my threads on jetting and you gave me a link to your site, which is a huge help by the way...i was gonna use your settings to start off the tuning process since you have a similar setup...thats why i wanted to know about the air filters
