I ordered to small a chain and need to add like 3 links. if you got three 520 masters and you dont need em, please send em to me. if they need shipping (which they shouldnt) PM for info and ill pay for whatever it costs to transport them.

Masters won't do it - they are only the outer sections of chain. With no inner sections, multiple masters won't link. You need a chain stub.

Hi Greg,
Actually, you need a different chain.
A chain that is the right length.
The reason -- if you try to extend an existing chain, even if it is new, you will add multiple potential points of failure, which is not safe, nor a good idea.
A chain with a master link is weakest at the master, which is not a big deal for a 40 horsepower GS500. But when you add multiple masters, you are only making it a matter of time before it fails.
It is dangerous and not worth the risk.
Buy a new chain that is the correct length for your bike.
Are you running the stock size sprockets?
This is a safety issue, and not one to fool with.

Best wishes,
