Always do it myself (other than first service). That way I know for sure it was done, and I know for sure which oil went in and that the filter WAS changed.
really appreciate the feedback everybody- i'm going to do this myself got a 6 pack of 10w-50 4T synthentic Castrol, KN-204 oil filter, and 10 crush washers for 69 bucks; have a separate small order of 4 o-Rings from bikebandit (6.99 shipping cough) I should be good for a while
