Just bought one, and this is my 3rd post here.
Max II, 1986, serial 7400.
Previous owner(s) installed Vanguard 20HP V-twin, winch, and full roll cage.
On edit:
I'd better recheck the registration. (The new title's being processed) I see from the list above that #7400 should be around 1984 instead. Maybe I remembered the year wrong.
