Just removed my arrestor on my fzr, just wondering if any one has just ported out the intake rib instead of buying the sleeve. It has plenty of material to port just curious. I ride at +4500 elevation and i need all the free mods i can to get this thing to move out of its own wake and not spend thousands of dollars. Allready installed diy ff exhaust and 4" intake and lets just say never seen over 60mph on the gps
