Buy a rear stand, a can of Maxima chain wax, a gallon or bigger can of kerosene and you're all set. Heck, if you can change oil anf filter, that's about 85 percent of the total service! Trust me, been doing my own maintenance for 30 years now! It ain't rocket science, the dealer service is a big rip off!
Chain adjustment, as I am sure you already know, is in your Owner's manual. Some may say those little adjustment marks aren't accurate, but hey, they're close enough!
Put her up on the rear stand, wipe that chain down and rear sprocket with kerosene, then wipe it dry with a dry rag. Rotate the rear wheel while appying the chain (no fling) wax.
Adjust the chain as instructed, buy a 36 mm socket at Kragens or Autozone or where ever. IMPORTANT: Before you remove the right fairing to get at that oil filter, remove the top three fairing fasteners and apply a strip of masking tape to that upper portion of fairing that won't be removed. You'll prevent scratching, see if any dealer does that for you!!
I'll get flamed by many on this next hint I'm sure, but again, trust me! After you drain the oil, only "hand tighten" the drain plug, then put a socket on the drain plug and give it just a touch past hand tight, it will not leak. Check all visible fasteners and hex nuts for tightness, pay particular attention to those phillips screws that hold the bar ends on and the couple of hex bolts that secure your windscreen. That's about it man, jump for joy, you just put $160 in your pocket!
And guess what? You have just done a much more thorough job than the knuckle draggers down at the shop would do!
