if u change pistons out a lot about how long does it take? this is for a 400ex too by the way

it depends on many things. skill, whether you have done it before, any problems that may occur, ect... I can have the top end off in about an hour, but other people it may take three hours just to dissasemble. i can do the whole thing in about three hours total. i reaaly depends but i would say about 5 hours for a average from running back to running.
