91 most of the time. On hotter days at the track (revving high) I'll put in 93 or 94.
By re-jetting, you probably mean re-mapping. No jets to change on a F.I. bike! Once you sort out your exhaust setup, best thing is to get a dyno tune with your PC3. Probably run you $200 - $300. Worth it.
ok cool, i figure ill use 91 most of the time.
oh really? that's weird the rep at one of the stores where I got the maintenace done said it may need a re jet...but like you said guess I mean a re mapping then. my exhaust setup is all sorted out, I'm sticking with the arata system, its dope and sounds perfect for the bike. i still need to get a new map for my bike since i only have a mac at my hands right now. i also need to pick up the program for my pc as well, so i can map it myself.
