I'm new to Buells, just purchased an 03 xb9r, my question is about the oil change. I know that the engine oil goes in the swingarm, but I keep hearing about the primary or transmission oil, I know there is a drain plug under the tranny cover but my question is how the F#@k do I fill it with oil after I drain it, if somebody could explain this to me using pics I would be thankfull since I always dealt with Jap bikes and the oil change is simple, thanks and sorry for being ignorant when it comes to these engines
