I just got a yz450f 05 and rode it for about 5 mins and it stopped and wouldn't start we took it home and drained the oil to find there was 4 litres in it and furthur inpection i found that the cam had jumped about a quarter of a turn and one of the valve caps had disintergrated there was also before all this happened very little compression with the kick start would most of this been due to the excess oil?
