Here's the story I've been riding for a year now and just bought a 2007 zx6 with 23000 miles as I can tell its all stock but I want to up grade more torque more speed and over all better performance the bike runs great I just want to grow as I learn to ride (I'm not Ritch) I service and work on my bike myself and am looking for advice as to where I should start my upgrades and if you can give me s little back story as to why,how,and what else I need to do now that I got that on my bike? Thanks for the time!
