well i had a look at a '97 gsx-r600 with 22,000kms on the clock. it has been tipped over and just has a few scratches on the right fairing.rubber is about half worn front and back,chain and sprockets are in good shape. he just got new plugs,and wires, cam chain tensioner replaced, wheels were powdercoated last year as well. also he is the first and only owner.i didn't talk to him personally, just his roomate and will find out a bit more about it's service history tommorow. i assume there should have been a valve adjustment done already? if not is it costly? also are there any inherent problems or things i should look out for on this bike. i can take it out for a test ride tommorow so i want to know what i should look out for. also from reading reviews on this bike it seems like it is not the greatest street bike. btw he is asking $6000 for it, but there is room for negotiations. anyways just let me know your opinions on this matter, it will be greatly appreciated. thanks a lot!
