Mechanics impact trip

Yesterday the mechanics impact group and Mr Mac went to Hauraki Plains Motors. We went there to watch Adam one of the mechanics fix a Honda crf250r 2005, when he got all the parts for the motorbike he told us how the piston works and how the cam chain was all jammed up. The mechanic wasn't sure what was wrong with the motorbike but I think the cam chain had jammed up the piston from going up and down or the oil was to old and it wasn't lubricating everything and making it run smoothly. At the end we asked him if he had any spare motors left and he gave us a lawnmower motor to take apart.
