What can I expect from a full service by a mechanic (Dirt Bike)?

Just out of interest, what should I expect a licenced mechanic to do in a full service to a dirt bike?

Bike: 2013 Honda CRF150RB 4 stroke

If you're creepy and have taken your bike to the same place as me before: I took it to RPM motorcycle Services.

What I'm hoping they'll do: Apart from things like the filters, oil levels, lubricants, etc. I'm hoping they'll get round to making sure the valves are right. Maybe it's just in my head, but I reckon the bike's lost a bit of power since I first got it.

Time since last service: 20-35 hours (I know, It's overdue)

Not expecting them to do this, but hey: Jetting?

Jee, this is getting way too long
Thank's in advance for any answers! -Harper
