What does this ad mean about a dirt bike??

I'm looking for a new dirtbike to ride but don't want to brake the bank. I saw this ad on the internet but I have no clue what it means. Heres the link: http://connecticut.backpage.com/Moto...Ad?oid=1624997

it has a basket case and is in good shape. The year is an 1987.

"Basket case"is a slang term for piece of junk, ready for the car crusher, good for parts, to much money and repair time to get running, good for someone looking for a year long project to rebuild on their spare time, not running, has to many problems to list, etc."nds crank"- the crankshaft is broken and needs a new one.The crankshaft for that bike is over $300 and the entire engine must be dis-assembled to replace it.
