Re: Tight section on chain
If you have a 'dry link' in an o-ring chain, the lube is gone from inside that o-ring. You can't put it back in there, so it will just get worse. At the same time, my 929 chain had a couple of stiff links when it was new. One of those was the master rivet link. After a while, I saw that the o-ring for that link was probably damaged when they installed it at the factory. The chain still lived a long time. It eventually developed several other tight links. It really seemed to hasten it's demise after I added a 15t front sprocket. It was probably the fact that I did not add the 15t sprocket until the chain already had 21k miles of wear on it, so there was a mismatch in the spacing of the pin distance and the sprocket teeth.
If I went 500 miles between chain lubes, my stock chain would never have lasted 23k miles and 39 track days. Every 200 miles or so is more like it. If the chain ever gets shiney, you have underlubed it. There should always be some lube visible on the chain. Rain will take the lube off in a hurry, so you'll want to lube it right after a ride in the rain.
I am finally replacing my chain and sprockets. I'm getting an RK 530 XS0 chain and some new steel sprockets. Cost will be under $140. This is a basic good quality o-ring chain. Not the very best, but as good as the factory chain that lasted so well. If I was going to a 520, I might have gone with the EVR-2 at double the price. If going to 520, it is not the chain that is usually a problem, but the life of the sprockets. If the sprockets get worn, they take the chain with it. The wear on the chain comes not from the exterior of the rollers, but from the interal pin stress brought on by the slightly altered spacing of worn out sprocket teeth. This puts all the stress on one pin at a time, instead of a set of pins carrying the load.
I decided against going 520 or aluminium, just to keep it long lasting. I even decided to go back to stock gearing. I had gone to a 15t front, which was fun for the track, but a bit buzzy for the street.
