kawasaki z900rs performance upgrade without ruining smooth street manners

kawasaki z900rs performance upgrade forum question

I am considering a kawasaki z900rs performance upgrade, but I do not want to ruin the smooth retro-road feel. Better roll-on is the goal.

I found this related page while comparing notes: kawasaki z900rs performance upgrade. I wanted a practical thread before guessing.

Before a kawasaki z900rs performance upgrade, should I check service baseline, air filter, plugs, throttle sync, chain, tires, brake drag, exhaust legality, ECU faults and fuel economy?

The bike is smooth but feels a little flat compared with another Z900RS I rode.

Retro style is nice; retro troubleshooting by guessing is less nice.
