I got four bikes for free and they all started and ran with normal dismantaling cleaning and reassembly.they sat for years '80 '74 '75
Free is ok if you do all the work yourself,if you have to pay some one to work on it NO!
Just be sure you have title and pick the last owners brains all you can about the last known condition ,and even then use the "force" to see if what he says fits the actual condition the bike is in.
See if he has any reciepts of past work ,what ever you can get will help your trip back the the road.
As ussual "if you decide to take this job...Good Luck,and we will be seeing alot of you .If not buy a runner ,lowest mileadge you can afford and cafe it.Because its all about the cafe
Im so far behind ,that I think Im in first.
