A little messy, but mostly just on the frame. The hard part is getting any type of drain pan under there. I just use an old cookie sheet.WOW! They have got to be kidding! That tiny allen? That has got to make a huge mess. Thanks Jeff. I NEVER would have found that.
Just curious, but why in the world would you do the 500 mile service yourself? Get your bike broken-in and some hours/miles on it and use the hell out of any potential warranty work.
Also the dealer does a "dump" of the rev hits and time at rev's as part of this service. If you end up having problems, you want to have the early histrory on the engine documented to the nth degree.
