Mate the dealer did the first service on my bike and did it for free as part of the deal. Now the dealers will tell you that you need to have valves checked on first service but this is not the case any more so if they try that on you is all bull.
Just do it yourself change oil and filer plus clean screens. It takes a bit of time but its no big deal.
If you do have a warranty issue between now and June and they wont cover it well that is just GAY! As most dealers will not have a problem with it.
Most owners do a better job than the shop mechanic anyhow.
