2003 zx12r common mods for street

what are common mods for a 2003 zx12r?i'm most concerned with comfort during 2-4hr rides and harnessing the big k's power lower/smoother in the rpm range while still getting 125+ to a tank.i'm 6ft 200lbs.i'm not so much concerned with top speed (150mph+),just getting the most out of this baby while touring/passing/street riding.thanks guys from reading earlier post i know i'm at the right place.

The first thing I did on my 01 was gut that damn cat...lets the heat out and improves throttle response. I think you'll find it in the same place on the 03 right before the can section.

Nothing much is needed for that kind of use. I recommend Heli Bars, maybe a slip on for a little more sound, a rear hugger to keep the suspension cleaner and some cosmetic changes to suit your taste. Gas mileage is pathetic, but I still get 150-170 miles to a tank, depending on the number of gas stations in the area. Miscalculate your mileage and you will find it hard to push, so err on the side of safety!

WTF? I get maybe 110 if I'm lucky. I've got a '00 with a full tsukigi titanium exhaust, PCIII USB with a very mild map, and -1 on the front sprocket on the rear. I ride about 25 miles a day, and on the 4th day after a fill up, I'm well into the red.

what kind of setup do you have? All stock? mods?

my mileage blows

Sounds like you need some helibars, soft luggage and heated grips if it ever gets cold in Houston.

My '02 has stock gearing, PCIIIR, Devil exhaust, K&N filters +3degrees timing and delivers a consistant 37mpg @ 75mph or below. My old ZX11 used to give 45-50mpg under the same conditions, even though it pulled a lower gear. I'm not exactly aerodynamic at 225 lbs. and 6 ft. tall either. Maybe the B models are just more fuel efficient! I've never yet reached my goal of 40mpg yet, although I have seen 39.

ships funny,, almost a 007 set up with the flip up doo hicky and NO2!
i run the Helis and a Corbin amongst other stuff,, those 2 should be first for the long rides,, maybe even gear her for the highway. i am a tad more than 225 and 6 foot,, i never take a chance,, i pull in for fuel @ 120 miles!
