with me having the 3ss, I think I got a good deal on a 3rtr for 100 bucks for my wife,the only thing it needs is a clutch and a set of tires, and a good cleaning? then I disasembled it to clean it and investagate everything and I took the head off to see the piston and sleeve of the 15fe, The top of the piston is black? completely black? the guy said he never tuned the engine? that whatever it was set from the factory was where it still was, so my question is can it hurt an engine to run it breakin, without retuning? he said he had only run like 2 quarts through it. And what is the black stuff? the engine runs good after it warms up so I'm confused? it looks like it ought to be hurt?
