Awesome! Thanks for the suggestions! I stopped by Tru Value and got a micro torch for $30 because there isn't a Harbor Freight within 50 miles of Southern MD. About 5 cycles of heat/PB Blaster, it began to work free. What I found inside was a white powdery build up of some sort of residue along the rim, just aft of the threads. I know it was clean prior to installing it last time (maybe 10K miles ago). Any ideas? (pics attached). You can see the residue on the screw threads as well. It almost appears as a salt powder (didn't care to taste it grin). I have been riding this winter, and there was salt brine on the roads, although not very often, considering the winter we have had. Could dried salt brine made it's way past the filter?

Anyway, worst part's over and I am not pricing a throttle body. Currently awaiting 2 new brass screws from Bobs. Whats the best way to clean that area out?

Thanks,

Aaron

Do you think it could be just a reaction from the Blaster? The other one did not have it, just saying. I would check it again in a few thousand miles but not worry about it.

I suggest a something like a brass gun cleaning brush from a .22 cal rifle cleaning kit & carb cleaner. Everything should eventually come whistle-clean.

DR has a good idea using heat after penetrating oils. There are some incredible mechanics on this forum.. Gonna remember that one!

You must live in a nasty corrosive environment. I suggest putting the whole thing back together with antiseize paste on the threads, the o-ring, and the outside surfaces. At least that way you can get it apart next time.

On my R1100RT to clean the BBS screws and their ports I used Brake Cleaner spray. Remove the rubber bungs from the vacuum take-offs at the bottom of the throttle bodies and spray the Brake Cleaner into the BBS screwholes until it runs clean from the vacuum take-offs. You can also spray up into the take-offs if there is heavy coking.

+1 on putting anti-seize on the BBS threads.

A gun cleaning brush is an interesting idea. What are the risks of a bristle clogging the air passage? Cleaning the bore of the air passage has always been a dilemma for me. I want to get it as clean as possible, but I don't want to leave debris behind, or damage anything. I like the idea of squirting cleaner up from the bottom, through the vacuum take-off.

CVS makes a "safety" swab that is useful for this application, and the tips seem to be attached more tenaciously to the sticks than is the case with many swabs:




Don't fix it if it ain't broke, don't break it if you can't fix it.

I recall now I used multiple Q-tips w carb cleaner (brake cleaner may work too) doing my R1100. Probably a little more friendly to the threads.

I use to ride all winter on salted, wet roads. My BBS did the exact same thing, but I had more white stuff then yours. For lack of any knowledge I was able to muscle mine out after tapping a oversized screwdriver into the slot. Good news is the new one worked perfect.

That is probably a combination of road salt and bauxite, which is what aluminium is made from, and what it turns back into when it corrodes. If you fill the area above the O ring with the silicone that Dirtrider suggested, it will keep it from happening again.
