Hi all, currently own a 2003 zzr600. I've found that when looking through forums for technical information that rarely is the year of the bike specified and therefore I don't know if what I'm reading applies to my bike. Right now I'm specifically looking for information on how to adjust the suspension to make it not as spongey without ruining the bike. I found a good write up , but again no year was specified.
was hoping someone knew of a list of what changed other than aesthetics from year to year.

Thanks.
