SeaFoam

 

Since getting my bike 2 1/2 years ago I’ve been diligently following the unofficial Honda maintenance schedule as known by Honda riders the world over:

 

1 Add gasoline of choice every +/- 200 miles.
2 Glance at oil once in a while, just to see there’s some in there.

 

I'm pretty sure this is in the book, right after "Your new Honda will give you many years of trouble free riding pleasure if you follow these few simple steps...

 

Anyway, having done this, the bike has lived up to its promise. Always starts. Runs smooth. Thank you Honda.

 

But in spite of my attentions, on a ride just yesterday I noticed a new and slightly disconcerting sound. Normally on longish hill descents while letting the engine braking keep my speed down I hear a reassuring rumblemumblemumble with an occasional quiet cough (pop pop). Yesterday it was more like mumble pop mumble pop mumble ka-BANG!! pop mumble mumble. And while I happily envisioned the BANG!! part accompanied by muzzleflash that would do the space shuttle proud, I also thought that can’t good. 

 

So I went back to my garage training, decided the thing maybe had picked up something bad last time I was at the local Gas’nSip and whatever that was was messing with the jets. Then, always one to take the easiest, most hopeful decision, I dug out some SeaFoam.

What is SeaFoam?

 

SeaFoam is, well, I’m don't rightly know. It’s promoted and sold as some kind of miracle engine cleaning additive. Uh huh. Importantly it seems to make a difference, maybe especially on carbureted engines with bad gas. I'd used this before in the cbr and it worked a treat.

 

Apparently SeaFoam, while a secret formula, is really nothing more than diesel fuel (kerosene?) and naptha and isoHEET. And what exactly do those things do in my engine? Again, I dunno. But there’s a Swedish guy who's figured out the formula for us. Here's his link:

 

http://www.hildstrom.com/projects/seafoam/index.html

 

He analysed the stuff, tried some experiments, and came up with some qualified conclusions. You guys know I’m a sucker for quasi-scientific approaches to pretty much anything, so I liked the link. He even explains how you can make your own SeaFoam. Cheap. Not that I’ll be making my own any time soon, but nice to know I could make it, and you can too. Go Sweden!

 

Meanwhile, I’ll give a can of the expensive store bought stuff a chance to do its thing. As directed, about 1 oz/gallon in the gas tank. I'll use up the can, but hope for positive results before it's gone. And I might buy some real gasoline too. Let's see it that does the trick.

 

 

(Ed. One month later. Did it work? Well, it didn't hurt. I've returned to the same long downhills on a nearby route to see if I could coax more backfires from the bike. Mmmmnope. So that's good. For some reason I'm getting a vague idea I have a lazy cylinder. It's just a feeling. Under load, everything sounds great. When idling or decelerating I may be picking up some kind of hiss. Like there's a vacuum leak. It's just a feeling so I won't be following up. You know I don't look for trouble. Obviously if a problem develops...)

Ten years ago the forks on my '92 looked pretty scruffy, though not quite as rough as yours. I had the forks off to get emulators installed and decided to try cleaning them up. Some good paint strippe

Following along, it looks like a lot of good information is being shared here so thank you everyone including the original poster Gebruiker.

 

Now I have 9 more pages to read to get caught up 😆

I might save you some reading by warning you that most all my entries are sortof experiments in bumbling. They contain a lot of information on what you don't want to do. It's the experts on VFRd that can save you time, money and misery.🙂

Nothing looked dodgy to me but the little hubcap thing wouldn't click in place. So I tried jiggling the nut. And it turned. By hand. It was loose. The nut. I could hand tighten the whole nut. By which I mean, I could hand tighten the whole damn wheel. 

 

Here’s the service manual. Nut number 1.

Thank you for bringing this to the attention of the forum!

 

You are correct, a properly staked nut will have a big dent in it.  Glad yours didn't cause a catastrophic failure.

 

I went out and checked mine and while the rear axle nut is not loose, no attempt has been made to stake the nut in place even though it is definitely designed to be.  I am wondering if it came from Honda this way?!

 

Thanks again.

Neither of us know the history of our bikes. Once I discovered the problem, I did notice what could have been a small staking dent maybe. But dent or not, it wasn't doing its job. Since it has never become a known unknown around here in 30 years, it seems unlikely to be a major issue. Unless of course, all non-stakers are now dead and therefore failing to report in...

 

 But now that you have doubled the sample size of unstaked axles, it might be a good thing for more gen3 owners to check into. 🙂

What about the unknown unknown? :laugh:
