I just pulled the carbs off of my 83 550L and they have been sitting for 30 years with no winterization. Needless to say, everything is stuck. I have it soaking in WD-40 while I search for a rebuild kit (gaskets and o-rings) . They are dual, double-barrel mikuni's. Any good resources?
 
No rebuild kit exists outside of what you can buy as oem parts.
Disassemble carbs remove diaphragms and get some rings from cycle orients.com.

Thanks, that's what I assumed after looking around. It just easier when there is a package. I think it's odd you point out to remove the diaphrams in particular. Is there something specific to them on these bikes I should know about?
 
Nothing specail they are just bigger.
I made the assumption you would be dipping your carbs in something like Berryman's It would eat your rubber bits and these are still available but insanely expensive.

I got my internal o-rings from robert barr of cycle o-rings super good price and fast rurnaround. There are only rings for the needle valve seats, the fuel crossover pipe and maybe the drain plugs IIRC.

Buy the carb intake o-rings while your at it. The seal the joint twixt the head and the intake runner pipe doohickeys.
 
10-4. I plan on breaking them down completely before soaking them in a carb clean bucket. These things are bad. Hopefully I won't strip or bust anything just disassembling them.
 
AHHHH! My jets are stuck! They seem to be crumbling when I try and unscrew them
 
Ok I have a crazy fix
That same thing happened to me
mine was crumbling with no means of extraction but for a machinist.

I used the square pointy tip of a chainsaw file. I checked the depth of one of the holes I had removed a jet from then I checked the inner diameter of the jet.

I selected a file with the appropriate size ( they vary) then lightly tapped it into the jet hole. The square steel tip cuts into the brass very handily.
I then used a small vise grips to snap the offending piece out.

Not an elegant description
to narrow a tip will bottom out
too wide will not get much "purchase" inside the hole.
