Hello together! After I did not have a motorcycle for a long time, I bought a GPZ 500S now. Actually it is meant for my son (will be in Dec. 18 years old), but until he has the driver’s license, I can take care of it. Here a few key data: Year of construction 99 13300 KM Black thrush on 34hp Pictures are in the signature Since the previous owner made the oil change at 12000 KM himself, the inspection is of course missing. I was at the Kawasaki dealer and those who think you should inspect the Is it necessary to have the valves adjusted (to 300,- cost). What do you think? Should I have the inspection done?
