Ok, I got the rocker cover from HMS and, as clearly announced, it is black with soot from a fire that ravaged a Colorado dealership (there is a little bit of molten plastic from the tsnk.

Besides sand blasting, what do you suggest to remove soot from this aluminum cover?

Acid would eat the aluminum, so that is not going to work. Neither will oven cleaner. Aluminum hates it.

Thank you!

I recall Mr Lineawearver saying that the carbon deposits in a aluminum head can be removed from an exhaust port with water.Soot from a fire should also be carbon based,so water and a little elbow grease might work as well.Worth a try?
 
it is the caustic from cleaners such as oven cleaners, Machine Dishwasher Detergents etc. that is the biggest concern with aluminium (and it is an alkali not an acid). You should be able to use normal/mild detergents. I suggest a hand wire brush might be the best alternative or a wire wheel even on a drill/grinder.
 
LeFrog,

have you ever tried a product called 'Blitz' from a company called Chemtech, it is the same company that makes the well known CT18 Truck wash.

I have used it on plenty of alloys, ford cast alloy rocker cover, KX125 cylinder, and DID rims as well as normal alloy product like when I built my forkbrace.

you can dillute it as much as you like to allow it to be gentle on the metal, and with a bit of brushing, with a corse bristle brush or toothbrush, it should lift the crap off.

Id definately consider re facing the sealing surface of the cover with fine emery paper on a flat surface (glass).

did you get the PM about the sidestand you are after??
 
Le Frog,
I know of a place in Van Nuys CA. that dose chem cleaning. They do a lot of restoration work on clasic cars and do a very good job of restoring/cleaning metal parts. I know Jay Leno has used them to bring back the finish of old parts, so they would be the ticket. Of course, I'm sure there are places like that in AZ. I would go that rought...you will be happy with the results :)
 
Drop it by work tomorrow and I'll throw it in a Cuda (water based industial parts cleaner) and see how it comes out.

No but I got a few quotes. It's about $80 but I guess it does not include the spring and retainer.
 
Damn, something's wrong with my Private Messaging, it's never worked.

log on to www.ebay.com/ and just do a search for 'husaberg', there is a dude parting what looks to be a nearly complete 2000 model, there was a sidestand, with spring, looks great, as did all of the parts, complete frame, tank, all plastics swingarm etc.

I had the ebay item no, but left it at work... Doh.

Tie the rocker cover to a string and pull it behind (a bike that runs) at approx. 95 mph through the AZ. desert. That'll take the tarnish off! :D

You can thank me later,
I like dark beer. :twisted:

Right now our desert is a puddle of cold mud. Thank you Colorado!

And our Suns did not take it to 16 in a row, because of the stupid blizzard over there that snowed them in and force them to land merely minutes before the game.

Dang it, Colorado! Now they have to restart a new streak.

Excuses, excuses! :roll:
 
Reviving an old thread here perhaps, but for what it's worth there have been several threads on some of the RD/RZ forums I read about cleaning Al bits and cases etc in antifreeze using a slow-cooker (like what you'd use to cook chilli or stew over a couple of days). Get the antifreeze hot (not boiling), drop the part in and let it cook for a day or two. Cheap solution so might be worth trying in this case.
 
I have used CRC "brake cleaner" on many aluminum parts. takes just about anything off. It's cheap at Autozone for about $3 a spray can.
 
Well, this was a badly burned part, my friend. Berger helped me with his industrial equipment.
