(WTF) What caused this???

I'm baffled :confused: :confused: :confused:

So, I keep the bike in an outside secured enclosure that is not heated and is vented to allow natural outside airflow.



The bikes been in there all winter with battery tender on. I detailed it before putting it away, and everything was perfectly cleaned, waxed, and polished. I go in and out of there from time to time, and I always look over everything while I'm there. Up till now, everything's been normal, even up till a couple days ago.
Then I go in yesterday and find this on the cooling fins and some on the trans case. Nothing else on any other aluminum parts. No work has been done in this area, or spraying anything of any kind, AND.... it's only on certain aluminum parts, but not others........

(Looks like dried road salt)











SO........ you get the idea..........:eek: :angry:

First fear was pitting of the actual metal, but you can see in the 3rd pic that I was able to get one of the upper fins pretty well cleaned up in a couple minutes time. Still needs work to be perfect.......

My first thought is that because of the moisture in the air having picked up some of the road salt thats been used in my area because of the snow, maybe that's what caused this to happen. But if so, then why not on all aluminum parts instead of just the areas that I found? Maybe some sort of electrolysis in the metals???
We're getting ready for another snow blast here in Maryland, but as soon as it's over, I'll be out there buffing the crap out of all the affected areas to get it back to show condition!!!!!!

I keep mine stored indoors and it has done it a bit...not a lot like that, but a bit.
That's a cool link Kickstart posted.

By the way...man...those reflectors have got to go!!!

The first pic (Storage) is an old one. :)

Now, back on topic......... So I skimmed the link that Kickstart posted on dissimilar metals causing such a reaction. Great link by the way!!!
Question now is, has this happened to anyone else and what to do to prevent it??? Does having the tender hooked up all the time contribute to this?? I'm just throwing some questions out there........ This is all new to me......
Thanks.... :D

Do you have a pool and store chlorine in the same shed? I know of one case where a brand new bike needed complete chrome replacement after storing his bike in shed with pool chlorine (ouch).

SHEEEESH..... don't say that...LOL
No pool & no chlorine...... Chrome is fine, it's the aluminum.

I had a NOS rear valance for my 70 Mustang stored in my cousin's shed along with his parts (he's my paint and body work guy). He set it on top of a bag of cement or something like that. When I pulled the valance out of the box to use it, there was about 6-8 inches MISSING. It had corroded right off.
I would really take a look at what's in the shed around your bike.

It's possible that the corrosion could be galvanic reaction.
Remove battery and place it on a tender with a piece of wood under it.
Any chemicals in the blue 5 gallon containers?

I have my bike stored out in a shed as well but it's in a bubble with desecant bags and I have the battery removed.
I would think that if it was moisture in the air then more of the bike would be effected. How are the hand controls any oxidation there?
In the meantime you may consider a little WD-40 on the engine, not sure if it'll help but it may.
Or it could be radiaiton from the reflectors as skid pointed out......

I have had this happen to my bikes during certain winter months. I think it is rapid oxidation due to temperature swings. I noticed this happen to my bikes during milder winters where the temps would rise from say 15 to 40 in a day. I can always polish the crap off without problems. If it were me, I wouldn't do any cleaning or polishing until the metal warms up though.

If the battery tender was not a quality device, the battery might be venting acid fumes.

Was there a rotten eggs smell?

That's exactly how the weathers been around here lately. 60 degrees one day and upper 30's the next..... That's a good observation..... :up:

I had this happen to a bike in the past! Don't wait to clean it.Mine pitted and did damage that was irreversible. After polishing it ,make sure you wax the living shit out of it to prevent the air from allowing the difference to happen again!:(

No... no smell at all. The tender is fairly new and never a problem from it.
The thing that confuses me is that 2 days prior, everything was perfectly fine. The fact that it happened so quickly is kind of puzzling.
As long as nothing is pitted, I'll be happy......

Just another thought....

If what you have is moisture related, a Goldenrod under your bike cover might help....has worked great for me...

Hope this helps.....:2thumbs:
