What is this starter sound?

I have a 1979 custom 12k miles runs great. Its cold now. I've been getting weird sound from my starter. The sound comes and goes. It usually comes on after like a minute of trying to start. A hard start. I got the bike this fall. Never made the sound. Once it got below freezing and I didn't ride it for weeks at a time, it would make the sound during the longer times it took to start. Once it started, the sound would go away on warm restarts. But when cold some machinery definitely changes, and there's a very different bad sort of sound after a minute or so.

[REVISING TO ADD INFO ON THE HARD START: Whew, it took like 5 minutes of cranking to start this last time. I vary all the options. Is there a standard way to hard start in the cold? I try choke out, choke in, throttled a bit, twisted a couple times, no throttle. Sometimes it starts turning over with starter still engaged then it quits when I release the button. In the warm weather it often only takes like a 1/2 second to start -- touch the button, bang. So nice.]

Can you tell me what's happening with this sound? Here's a link to the Youtube....

Stabilizing the fuel in the tank won't help what's already in the carbs.

READ the FSM from cover to cover. And when you are done with that go back to the beginning and start doing everything in the maintenance schedule and the chapter on maintenance.
that's not gonna happen. oh well! i'll wing it and do what i can as needs arise.

my ignorant hunch is that now that Stabil is in the tank and I rode it for an hour today that the Stabil is now in the carbs.
You got lucky this time.

Continuing to ignore the maintenance schedule now can only lead to grief later. Have you at least set the camchain tensioner adjuster?
haven't done much of anything. don't know this adjuster. i suppose the bike will die at some point. i'll probably get in a few repairs along the way. i don't have it to preserve it. i'll use it. hope to get a few years out of it. yes, it's abuse. I also have a wonderful huge old Ariens snowblower from the same period that i barely keep running. i also have bicycles older than the CX500 that i ride hard every day and put away wet and they keep working. i swap out parts as they wear out.
I've always said that CXs don't die, they're murdered with neglect.

Routine maintenance will keep your bike running reliably for years. Among the things required for a long bike life are frequent oil changes and routine valve gap and timing chain tension adjustment.

As with many a mower or weedie-wacker.....people will curse em but run the same plug and filter when it left the shop 5 years or more ago....

If the factory service manual is too much of a read consider reading through the owners manual. File:1979 Honda CX500 Custom Owner's Manual.pdf - Honda CX and GL Wiki
See pages 70-74 for adjusting valve gap and timing chain tension.

great way to deal with a 40 yr old bike. Not
This thread can't be serious...just wow.
The helping hand here is sounding more like preaching fire and brimstone. If I didn’t know better I’d think he is riding one of YOUR own personal bikes? Well intentioned but getting a bit heavy handed IMO.

how easy is it to adjust valve gap and timing chain tension?

I've never cleaned a carb.

i'm concerned about slippery slope and making things worse.

i understand that you can keep your bikes running and mine will die. hopefully, as i said, i'll achieve my stated goal and get a few years out of it. i'm not interested in proper, full maintenance. but i can do some things. i can change oil. i've never been inclined to fiddle w a carb. it wd truly be best for me to have a bike w fuel injection. that's required nothing from me on any vehicle in past 20+ yrs. nice.
If you do any wrenching on your bicycles you should be able to set the valve gaps and adjust the cam chain tension. Described for bike owners inthe owners manual linked in post #28.

(#23 noted...)

Is there any "small engine" maintenance classes or "motorcycle engine" classes near you...?
You might find that a good starting point to get some confidence.
no time for a class. ... but i can work on anything on a bicycle. rarely have to.
When I got my first motorcycle I called a childhood friend who had grown up to be a motorcycle mechanic and asked him if I could bring it to him when it needed work. He said "No. You've been working on bicycles since you were a kid so you should be able to learn how to work on motorcycles too. Get a shop manual and when something needs to be done on it sit on a box next to the bike, read the section in the book about the job and call me if you don't understand something".

I wonder if there is someone on the forum close enough to get together with you and show you some of the basics.
If you can adjust derailleur gears you can do a valve adjustment.
I've never been good with derailleurs. Valve adjustments are easy.

It sounds like dry starter bushings. they make noise under load sometimes, depending on temperature.

Because these bikes are so reliable you will probably achieve your few year goal. It’s unfortunate your goal isn’t to learn about your bike and how to maintain it. You might come out ahead trading your bike in while it’s still running for a newer one with fuel injection and an onboard computer and no personality. Happy riding.
