Buying a used 4 is scary too. If it eats out on you from the PO's abuse(aka a ticking time bomb) you could pay over a grand to fix it easy if the valves get messed up too. Also, if the engine grenades in a 4t(unless it's a honda, because they have a separate crank/tranny) any metal shards in the crank case will go into your tranny also. So if your bike eats a valve you can end up with a totally destroyed engine. Jos will tell you it shouldn't cost anymore than up front purchase price.
