Thats the Cheap way of doing it. Like anything in life you can spend the money to do it right, or you can rig it to work. Thats what they did. You really should have a chain thats the proper length and a New cable of the right length also. That being said, as long as you check on it from time to time, and keep the chain lubed, you should be ok. Many people go this route, and it has proven itself to be relatively safe.
The extension is designed to keep it from wheelieing, so that being said the bike will be more forgiving of quick throttle inputs, however as a trade off, its going to be a pig around corners. The length is going to make tight corners harder to navigate, as well as forcing you to lean harder in normal riding.
