chains

every time I ride my brothers honda 200sx the chain gets loose and I have to adjust it. It has a fairly new front and back sprocket and chain and i only ride for about an hour or two. is this just because it is old or what?

sounds like your bearing carrier needs new bearings. They only cost like 10bucks , but takes a little work to get them on. Its alow called an axle carrier.
