I park mine in a shed. Honda is replacing my lower for bracket under warranty

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,,,,,

But again, without a larger sampling, or reports from those who park outside under a cover and DON'T have rust issues, we are only speculating at this point. I wonder if Chris on the UK forum parks his outside under a cover. I will ask him.

Well Chris says he parks his in a ventilated garage, never under a cover. Was hoping there was something that would link these reports together. Doubt Honda will ever tell us why.

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

I've been following this thread since it started. I have some rust in various areas. I ride the CB infrequently and it is garaged. Occasionally the outside temperature will rise 20 or 30 degrees in a few hours along with a big rise in humidity. The result is, everything metal in my garage is wet with condensation. I try to get to the bike right away, toweling it off and running the engine for a couple of minutes to dry it off.

As soon as I noticed the rust I got some ACF-50 and applied it liberally to almost everything except the brakes.

I remember my high school biology teacher saying that rust was caused by bacteria, so I went looking for some confirmation of this online. There is a fair amount of info on microbially influenced corrosion but most of it deals with sewer systems, water pipes, and jet fuel tanks. Turns out there are bacteria that love jet fuel and they corrode the insides of tanks.

I'm no scientist but I think that in addition to moisture and salt, microbes are a factor in this rusting problem. The different reports make it seem random: covered, not covered, clean, dirty, dry, wet, etc. but apparently the concentration of microbes in a specific location is also a factor.

I found a product for rust removal that no one had mentioned. I think I will order some and see if it helps my situation. http://www.evaporust.com/evaporust.html

Tomorrow I'll post up some pictures of my rusty spots.

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.

By the way, any suggestions on how to remove rust and inhibit it will be gratefully received.

Cheers

Well, I don't see anything on mine… But I'm gonna give it a few strategic squirts of WD-40

Ok, Ferret asking another dumb question..what is an oleos?

I wondered that, too, Ferret, so I looked. I think an oleo is "...A type of shock absorbers on aircraft landing gear". By implication, the shockers.
