My 99 Bird is stock apart from a K&N air filter, Denso iridium plugs (0.4mm tips), Penrite HPR 15 engine oil (15W60) with a Nulon oil additive (E20), a Toyota LandCruiser fuel filter, an ATF cooler to put the fuel through to cool it down, a pair of Yoshi RS3 slip ons, std sprockets, a Powercommander II (still on factory installed maps), Pirelli tyres (Diablo on front, GTS on rear), runs an 11.00 sec 1/4mile (no burnout, no power stand), (the clutch doesn't slip) but on normal bitumen road, power stands in 1st, 2nd, 3rd, upto 190kmh, all using 91 ron or 95 ron or 98 ron fuel.
The bike has as much power as one could use with out it wanting to do a back flip.
I find this an advantage against the guys on R1s, GSXR1000's, ZX900s.
There are guys over here sqeezing 300+hp out of the Birds engine to use in Sidecar racing, and in the Aussie midget Supercars, (they have m/cycle engines in them, all sorts), all naturally aspirated.
