There is a link to the 8/2006, www.motorcyclistonline.com, on the entry page of this group that refers you to a "Smart Money". In this article it states that the Blackbird has had instances of oil leaks around the crankcases. Especially, "where the balance shafts live."
I was hoping that other members have encountered or heard about this and had some tips. Just want to avoid the trip to the local Honda dealer.
