My baby, my first bike, my Honda CB750 Custom.

I’ve kept a journal off and on all my life, and consistently for the last 40 years. While, for me, the simple act of putting things down on paper is beneficial, it’s also a very interesting thing to go back later and read what you wrote. Here’s something I just ran across, from October of 1992. This was on my Honda CB750, the only bike I had back then.

I stayed a while longer, then got on the bike and headed home. Turning off Federal onto 67th my chain jumped off the sprocket and I had no power but could roll, and did, till the rear wheel locked up right out front. Jack (my neighbor across the street) helped me get it to the garage and this morning he helped me get it back to where I can at least ride it to Legends (a motorcycle shop just up on Federal a couple blocks from me) tomorrow. I’ll need a new chain and who knows what else.

OK, several things here. I had just come across town and this could have happened anywhere but it did happen just about 200 feet from home. How lucky is that!

Also, the chain jumped off the sprocket? How loose must it have been, and how negligent of me not to have noticed. I had been on I-70 much of the way home and what would have happened to me if the chain had come off at 70 mph? I mean, the rear wheel locked up. I might not be here writing this today.

Then there was this a few days later.

Got my bike from the shop. $55 for a new chain and installation but now the foot brake is sticking and causing a problem.

Yeah, you read that right. Just $55 for the chain and installation. Of course back then that was actually a big hit to my wallet. That’s inflation. But inflation is also the reason you can buy a house and have a payment that is a real stretch, but some years later it’s not a stretch at all. I’ve been a beneficiary of that and I’m sure many of you have as well.

I haven’t yet reached the next chapter in this story in my reading but I’ll reconstruct it here from memory.

As I noted, the brake was sticking. I had no idea why. I soon found out.

I was out at about Colfax and Monaco a few days later and the brake seized completely. And it wasn’t the rear brake it was the front brake. I must have gotten things confused previously–I was still pretty new to riding motorcycles at this time.

I pulled off the street and got down to check on the problem and in doing so I touched the brake disc with my finger. Yow! That sucker was so blazing hot it scorched my fingertip and left me with a second-degree burn. This is not good.

I was way across town but I figured this had to have been a result of something the shop did, something they did not set up properly. So I called them and told them where I was stranded and why. And here’s another thing I don’t think you’re likely to see any more: They sent a guy over with a truck and picked me up and hauled me back to the shop–no charge.

It turned out they had adjusted the cable on the brake a little too snugly and apparently the pads were in constant contact with the disc, gradually building up heat and expanding, until things seized. They readjusted it and that was that.

OK, so here’s one caveat. I know both of these events occurred. I’m going from memory saying one led to the other. I may read on in my journal and find that they were separate events. I’m simply not sure at this point. But they both did happen. And they both hark back to my title up above: Things Change. They certainly do. For one thing, that shop is long gone, as motorcycle repair shops seem to have a penchant for doing. And you’re not very likely to get that kind of service these days either. Heck, you go to an Italian restaurant these days and the bread sticks they used to give you are now available for a price.

The only constant is change.

This chain has served me well but now needs to be replaced.

When I got a new tire on the V-Strom the guys at the shop told me the chain was pretty stretched and needed to be replaced. That was no surprise–I’ve had this particular chain for a long time–but it got me thinking. How in the heck does such a large mass of metal stretch? I mean, do the many individual pieces that make up a chain actually get longer?

I decided I would do some research.

One of the first things I encountered was a whole other question: Do new motorcycle chains stretch?

Heck, I wasn’t thinking at all about new chains, I was totally focused on older ones needing replacement. But apparently new chains do “stretch.” That is to say, when a chain is assembled, all the pieces are more or less in place but once they are on a bike and experiencing stress they all sort of fall into functional place and that can result in the chain being a little looser. It is recommended that you do an adjustment after the first several rides with a new chain. Then you should be set for quite a while.

But that’s not the same phenomenon as an old, worn chain.

In the case of an old chain, it turns out it really isn’t the individual pieces getting stretched so much as worn. A chain has all these links that are joined with pins. The pins are projecting through round holes in the links and they are what allows the chain to flex. What wears is the pins against the holes, so these initially round holes get rubbed away so that they are no longer completely round, but become elongated.

That enlarging of the holes effectively allows the entirety of the chain to become just a bit longer. Mind you, we’re talking only a fraction of an inch over the entire length of the chain but it is enough to make a difference. If you want a detailed explanation here’s a good video.

Now, I know the V-Strom needs a new chain and sprockets but I figured all along that would have to wait until after I get back from the upcoming OFMC trip. I hope that is not going to be any kind of problem because it’s looking more and more like I may be riding the V-Strom on the trip. I was hoping Joel would have the Concours ready in time but that is starting to look doubtful, although I’m still awaiting the final word from Joel. I’ll go into that issue in my next post.

My motorcycle had a small oil leak. And thanks to my lack of mechanical skills, it now has a giant oil leak.
