>My process takes over an hour, is very tedious and expensive, and doesn't produce good results in my opinion.
And it's completely unnecessary.
You really don't need to clean it like you're doing. It's total overkill. Between my mountain bike and the various motorcycles I've owned, I pretty much never clean my chains and half of my riding "career" took place in Florida where it's always damp and humid.
This is the only lube you need: https://www.amazon.com/DuPont-Teflon-Chain-Saver-Self-Cleaning-Lubricant/dp/B00KMMFE8Y
Fold a paper towel up, hold it behind the chain, then spray the few inches of chain in front of the towel. Then move the rotate the chain and repeat. It should take all of 5 minutes to do.
If you want to avoid some of that mess, try using a self cleaning chain lubricant.
I use [DuPont ChainSaver](https://www.amazon.com/DuPont-Teflon-Chain-Saver-Self-Cleaning-Lubricant/dp/B00KMMFE8Y\) Similar benefits. It works great on my road bike. The FG bike doesn't seem to care! Lol!
Yea I leave it for about 700 miles, then clean it and use Dupont's chain lube
Dupont Chain Saver Wax. I have high vis yellow wheels. This minimizes dirt and keeps it feeling smooth. It goes on the chain clear also so it looks cleaner. I also use a grease ninja because drunk shopping once.

Yes, that's your master link. A chain can certainly die after just 6500 miles if it's been neglected.
If the master link is sticking and none of the others are, you could try replacing it to the tune of about $10. http://www.revzilla.com/motorcycle/did-525vx-x-ring-chain-master-link
As far as continuing maintenance on your chain, I highly recommend Dupont Chain Saver. A $9 can lasts me about a year of daily riding, and my current chain is about 12k miles old with no sign of quitting.
That stuff looks good
This is a terrible price BTW, should be at walmart-- http://www.amazon.com/DuPont-Teflon-Chain-Saver-Self-Cleaning-Lubricant/dp/B00KMMFE8Y
Do yourself a favor and get a rear tire stand to get that wheel off the ground. It'll be much easier to spin the rear wheel.
DuPont makes a terrific chain lube and I've been using it for years: http://www.amazon.com/DuPont-Teflon-Chain-Saver-Self-Cleaning-Lubricant/dp/B00KMMFE8Y
Here's the brush I've been using for many years (buying replacements when worn, of course): http://www.amazon.com/Docooler-Cycling-Motorcycle-Crankset-Cleaning/dp/B00GRQLDWU/ref=sr_1_2?s=sporting-goods&ie=UTF8&qid=1428941855&sr=1-2&keywords=motorcycle+chain+brush
Lots of people will tell you that WD-40, being water-based, will dry out the O-rings in the chain, but I've never had any issues and have never been able to find a better solvent that can remove the dirt and grime from my chain like WD-40. My process looks like this when cleaning/lubing the chain:
1) Ride the bike for at least 10 minutes to get the chain warm.
2) Find a large cardboard box and place it under the bike.
3) Prop the rear wheel up with my center stand.
4) With the right hand, slowly spin the rear tire and spray the chain with WD-40 with the left hand, avoiding the tire as much as possible. You want a thin coat at first, getting the sides and middle of the chain.
5) After one full revolution, get out your chain brush. You'll notice the one side has a place wide enough for a chain. Put that end on the chain and quickly spin the tire with your free hand. I spin my forward so I'm not flicking gunk, but it won't matter much either way.
6) Once you've gone a couple of revolutions, clean the brushed gunk off with the WD-40. The black stuff should be falling onto the cardboard, not bare driveway.
7) Once you've got all of it off, spray it down with water, turning the wheel for a few revolutions. Don't lube it yet. Get on the bike and ride it for at least 10 minutes.
8) This gets the excess WD-40 off and gets the chain warm. When you return, use the thin straw on the nozzle and, with one hand, get a clean shop rag and place it under the chain.
9) Carefully spray the inside and outside of the chain as you spin the wheel very slowly. Done!
