James I am new to the posting thing. I have read several posts on BK mod and jetting. My jetting is the following in my signature, I have no clue what the stock MAJ, PAJ,and Needle Jet numbers are as they are not listed in my manual. I also have the EJP needle. Should I use it or the stock needle. The bike runs well the way it is but I am not sure if I need to change the MAJ,PAJ,and Needle Jet? How much will all these settings change with the BK mode? I live and ride in the Calif. desert 2000 to 4000 feet. Any help would be appreciated.
