I took both of ours in, I wanted no issues when it came to warrantees. They adjusted and oiled the chain, checked nuts and bolts, adjusted e brake which needed adjusting (they figured it out on their own) checked my valves, and would've changed the oil, but I'd already done that. I know for a fact that they checked valves too cause there were just tell tale signs of it. Our clutches were whacked out of adjustment too, but that's an easy fix. It was just nice to know I wouldn't have issues with warrantee, although if I'd known that it wouldn't have voided my warrantee, well, I might have done it myself. I paid $125 american per bike.
