The steering stem bearings had a recall on the 2002's, check if yours was done. Also, get a steering damper as this bike needs one, other than that they are a little under-powered compared the other "litre" bikes but they are definitely fun. i would also recommend getting the front forks resprung & revalved as the springs are way too soft at .70 kg. and the stiction on mine was close to 14mm
I have a full erion exhaust (erion map), PCIIIr
, flapper pinned, and it only dynoed at 138 rwhp, now albeit with some custom mapping and other fine tunings i should be closer to 145hp.
If you are willing to dump some money $$$ into upgrades you can make it track competitive so long as the other guy isnt doing the same thing to theirs, plus the new technology on the current models really puts this bike at a disadvantage when it comes to overall geometry, mass centalization, etc.
will definitely need:
* steering damper
* new suspension
* 520 conversion plus -1/+2
* full exhaust w/ PCIII
& good map
* Forged Alum or Mag rims to reduce rotating mass
