Rust on lower fork bracket

Ferret,

I've been watching Wheeler Dealers car show on TV and am learning to speak Brit from that

Learning English from Mike Brewer is like learning child minding from Michael Jackson.

Well, I'll be go to heck. I just read this thread, walked out into the garage, don't want to be a Debbie Downer but, my CB is showing some rust also.
I will email these pics to my dealer tomorrow. It is just the left side as you sit on the bike. The right side shows zero rust.





I have rode in the rain some. But my bike has been in a 72 degree basement since Dec 1st. I will report back what dealer has to say,,,,,

For rust you need moisture. This can take the form of visible moisture, rain, dew, fog, tapwater (cleaning), or not visible, high humidity for example. My point re the cover was that they do tend to be humid inside. A humid atmosphere even in a 70deg closed shed or garage will give conditions conducive to rust. So Ole, do you have a hygrometer in your garage? If so what is typical winter humidity? If it's snowing it will most likely be cold but humid outdoors and even if your basement is heated it may still be humid.

The humidity in my garage (doesn't need to be heated in Sydney) varies from 20% to over 90% depending on the ambient. After cleaning I generally spray forks, oleos, linkages etc with a rubber friendly silicone spray. (As an aside, Cormanus, I don't use the high pressure cleaner directly on seals or areas where the electrics may be affected.)

My bike has been wet for periods of over a week (on a ride back from Adelaide last year it literally pissed down for five days straight and the ride to and fro the MotoGP this year was only slightly better). However my bike doesn't show the rust that I've seen in this thread. When I said, in a previous post, that there was some slight corrosion at the underside ends of the oil cooler pipes it has made me think that this is an area that I haven't been careful with.

Once again this rust thread has got me puzzled. I have had some trust in Honda as far as build quality goes so I would hate to think that I have just been lucky.

Cheers

Pterodactyl, what silicone spray do you use?

Thanks.

Humidity has to be a factor here. In the wet season it can be incredibly humid—in excess of 90%. I'm clearly going to have to rethink how I protect the bike when it's parked.

Cormanus ,

Don't use WD40 or any spray that is not suitable for use on rubber. For instance, I use INOX to prevent corrosion on kayak and fishing gear. Great stuff but can't use on rubber. I have been using a good grade silicone spray but even that is not suitable for prolonged use on rubber. Don't ask me what prolonged means, in this case it's one of those weasel words

However, all is not lost. On the cb1100forum.com there is a thread concerning aviation grade lubricants and water displacers. If no one jumps in I will get off my blot and use the search engine. These products should be available in Oz, after all, we can fly aeroplanes to (joke guys, please don't flame me). I am going to follow this up but, from memory, I think the distributor was QLD based so give me a hand* if you like.

Cheers.

Thanks popgun

I work on Navy aircraft (DOD civilian). Ok, I work on radar, but the mech in our office says that oleo struts work almost exactly like the forks on a motorcycle.

There is very little difference. The three oleo struts on my plane work just like upside down motorcycle forks (i.e. slider is on top). There's a provision for adding pressurized air for additional cushioning effect, which is present on some motorcycle forks (but bikes tend to use vastly lower air pressure).

By the way, after a year out here in the desert, where rain is rare and humidity is below 20% most of the time, not a spot of rust on my CB11. It sits an unheated / uncooled garage uncovered when it's not on the road (which is 3-4 days a week).

Wow, with all this Yankee ingenuity nothing, but nothing, can go wrong . The Rust Fairy is doomed.

Cheers all.

OK, so I sent the pics to my dealer. Then called him a couple hours later. He agreed with me, it is not right. He called his Honda rep and the rep told him Honda will make it right with me. But the dealer needs to "put his eyes on the bike" before anything happens.

So I will drive it over there and let him do just that. I'll keep you all informed on what happens.

[Cormanus]

Pterodactyl and popgun, thank you very much indeed.

Waddaya know? There's a stockist a mere half an hour away. Sadly he might have to wait until next week as I've a heap to do today including getting some of that rust off the bike and getting myself back to Brisbane. Let's see.

Thanks again, guys.
Wouldn't it bloody rotate you! They don't have it and at least one dude there thinks they can't get it any more.

Grrrr. I'll concentrate on cleaning the bike today and get back to the longer term fix in due course.

BTW, one dude in a bike shop yesterday said Turtle Wax is as good as anything on chrome to stop the rust getting in.

Ole: good luck with your discussion with the dealer.

Cormanus,

The ACF-50 would be for the metal parts. The 303 is for the plastic stuff. I had 303 on the brain.
