i just bought a 1991 ZZr250 for my first bike and because i haven't got my license yet i got my brother to ride it home for me and it went fine without any abnormalities. two days later we took it for a run around the block and found that when its in neutral it makes a heavy clunking noise but when you pull the clutch in the noise goes away. what would this be? i plan on getting it serviced when i get my license but im hoping it doesn't cost me much.

And if the chain is THAT loose, you probably shouldn't ride it until it is adjusted.
It might also be an indication that it needs a new chain and sprockets.
I hafta wonder if the noise is while moving or sitting still. If moving then yea as has been suggested check your chain. I don't miss having a chain. I've heard some on bikes rolling down the road that you just know it's going to be coming off very soon.
