Suspension set up and steering dampner.

 

I'm with the concensus on this. Modern bikes have more power than we can use anyway, so spend the money on how to stop and control the power in the twisties.
Brakes, shocks, fork work.

 

could the mystery mod he was talking about be a power commander?

 

I am going to say no??? If I am correct that year bike was carburated. PC is only for Fuel injection... Plus a PC does not use that much power. Maybe some type of timimg advancer is the only thing I can think of like a TRE????

Yes, the 02 ZXR is Carb'd and he already must have a dynojet kit judging by his sig. I'd recommend some Race-Tech suspension parts & tuning for the forks and an Ohlins or Penske rear shock. Better yet, upgrade to a complete front end with inverted forks from an 07 ZX6R. I'd recommend a BMC or K&N for power to go with what you have already.
