I think I remember the chains were 110 links and 520 pitch, correct?

Here's the chain I was looking at on bikebandit:

For the rear sprocket:

For the front sprocket:

My question though... for the front sprocket, which one do I need to get?  They each have a different number of gears.  Also, should that rear sprocket work fine?

The rear sprocket is 6 teeth up from the stock 39 tooth sprocket so it will increase your acceleration some and want for the bike to wheelie when accelerating.  The front sprocket people have used all of the various tooth counts but depending on your riding style would determine how many tooth sprocket you want.  You should probably read the wiki about sprockets and on there has a chain link calculator to tell you how many link chain you need depending on what size sprockets you get.

Don't get a roller chain unless you want to oil it every gas tank. If you need to go on the cheap get a KMC chain from ebay.

I have one and keeping it on the loose side of tension it looks like I'll have a 50,000+ mile chain. A roller usually wouldn't go past 15,000 even with careful maintenance, I know cause I had one on my Honda Rebel and it wore out in 15k.

Thanks for pointing that out.  I'm just going to go with the stock options.  i'll try to get some extra power out in other methods.

What are your thoughts on X-ring vs O-ring?

Here's an x-ring chain:

Actually, I think I'm just going to go with the O-ring chain.
