I'm selling a ninja 250 with no title in hand. i bought the bike as is from a friend who was several years behind in registration and was going to use the bike as a track bike. discovered that motor needed replacement and was out of my budget. now i want to sell the bike with no title. what should i do? do i need to write a bill of sale? if anyone has done this, any help would be great. also i'm located in CA.
