i might have to get a 98 400 because i don't have the money for a new one. what is a good process in checking out 4 strokes? i havn't had a 4 stroke for a while and i don't know how to make sure i'm getting a bike someone took good care of. i don't want to get a used one unless i'm absolutly sure its going to hold together and how need stuff like new a electrical system, top end, clutch, valves, ect. thx.
