That is correct.
The air pollution device was mandatory for sale in the State of California, and the jetting was a bit leaner.
A richer pilot jet should cure the slightly lean condition caused by the removal of the tank vent fume recirculator, or whatever it's called.
As for many bike parts...... the big four Japanese Makers Parts may be found at bikebandit.com, complete with online parts fische style blow ups.
Everyone I know removed the air canister and had no problems after bumping up the pilot jet one notch richer.
It should work for you.
