I decided to do my own at 355 miles and all I have to say to everyone running in their new bikes is to do it! At this mileage the drain plug magnet had quite a bit of fine filings in it (a black sludge). The filter is all black and the filter cap had some sludge on it as well. Took me two hours with receipts and pictures as proof. I will take it in on the next one as there are more complex bits to take care of then. While I rather give the business to the business to help keep them in business, this was a chance to get to know my bike better and have a little spending cash for that next Suomy helmet that I want, hehe. BTW even the oil filter cover facing the ground is a machined work of art with the MV logo (even though no one ever sees the part), simply beautiful and a pleasure to service.
