Re: k7 600 won't start need help!
Don't get me wrong, but you seem eager to replace parts, hoping that it'll fix things. A no-start condition in a bike with unknown history, can be due to various causes. Your best bet is to troubleshoot the problem methodically, as others have suggested, starting with measuring the battery voltage (as getting some lights to turn on doesn't say much about the battery's condition).
If you don't know what to test, or how to test it, we can provide some guidance. If you don't feel up to it, or don't want to bother, you'd best get it to someone else.
