I just completed my own oil/filter replacement as the bike as 21750km and the warranty expires next week.
            
 
             I had it done by the local dealer before.
             
            
 I used to do oil/filter and all sort of work on my GSE500 and my VFR750, so I wasn't expecting any trouble.
             
            
 but wow, this is messy !!!!
             
            
 3 drains for the oil ! (frame, crankcase, filter drain)
             
            
 I'm glad I saw it coming and had a lot of newspapers under the bike...I still managed to get some oil on the concrete in front of the house 
            
 
             
             Otherwise, pretty straightforward with decent funnel to catch/fill in the oil.
             
            
 the best thing being: with the Yamaha aluminium bashplate, the oil drain is accessible without removing the bashplate, happy days
