why does my 400ex keep burning rings every month?
um, rings won't burn out of the cylinder, they may break apart and end up in your engine oil. the blue smoke sounds like burning oil. Just to get this striaght are you saying you remove the cylinder once a month and put a fresh set of rings on the piston? if that is the case you need to have the cylinder bored to the next oversize and install the mathcing piston and rings.
