:blah: How many miles & hours is on the bike? Has the top-end EVER been rebuilt, IE Rings, Piston, Piston Bearing, New Gaskets? Wheel bearings are cheap & easy to put in. Rings, gaskets, Piston & Piston bearings not bad either. If your going to rebuild the top end-Get the piston kit. It comes w/rings, piston & piston bearings. Gaskets are seperate. Has he ever flushed the radiator.Has the clutch ever been checked or plates & springs replaced? Has the bike ever been in a serious wreck(I would think you would know that) And why is he getting rid of the bike? Thats the problem w/buying older bikes. Its better to know if the bikes been maintained well, before you buy into a MONEY PIT. Also, a word to the young-Don't do business with friends or relatives-Just a piece of advise. :(
