Re: Looking for some advice.
Go get it now. Words are cheap and besides, you never know what could happen to the guy who has your dad's bike. What if HE gets hit by a Mack truck and then you can't prove who owns the bike?
On the other hand, if the title is still in your father's name, you may have a legal precedent to win that fight but still, not worth it.
I'd do what I had to do to get it back now.
