Some people check the valves and others do not. The dealerships love to make a little extra from the customer by charging to do the valves. We have a local atv garage that will do the valves for way less.[img]i/expressions/face-icon-small-smile.gif[/img] I would check around to see if someone would do them for less. If you want them done at all.

Change the oil, check the air filter, and lube what needs to be lubed.
