Also, how many miles are on it? Hondas (and every other bike in the world...) have a set mileage for various tune ups, and mantinence. (i.e., my 350 is due for a valve adjustment according to the factory at 14000 miles.) See if the P.O. has a mantinence history, can he prove things were done when they were supposed to be? And DO NOT just take their word for it... I got my 350 from a bike shop here that ONLY works on vintage Japanese bikes, and has been in business for 30+ years, and was told it had just been gone over thoroughly... Well a leaking petcock, gummed up carbs, plugged up muffler, bad battery, etc. later, and im still finding half assed "fixes". Most of these old Hondas, if they have been properly maintained, are fuckin bulletproof. Honda has always prided itself as being an "engineering" company above all. The manufacturing tolerances on most models (there were some lame ducks...) are damn near perfection. Ya gotta hear it run though before droppin any dough... Get on it after its warm, and shift through every gear and see if it engages and power is being transferred. You dont have to go on a long ride, or even leave the driveway, to at least get an idea of things being in line.
