Start with what is wrong. When was the last time it ran?
No start I assume... Do a compression test first off. Ace Hardware sells a good tester. 120PSI or better is needed for the bike to run.
next check for spark, and fuel in both the carb, and on the spark plug.
Check these, and post back. The only reeds I have ever seen go bad/leak/break were in a 500HP Mercury outboard that ran expansion chamber exhausts. Yours are fine.
