20K miles on a Buell is very low mileage.
However.... you have posted pics of the sludge buildup in your intake tract caused by blow-by.
Blow-by is caused by leakage past the cylinder wall and piston.
That leakage is allowed by piston rings that aren't sealing properly.
There is no 'repair' for piston rings. Just replacement.
When you replace piston rings, you should either carefully measure your cylinder (and then machine or hone them depending on what you find), or just replace them with new.

Keeping an eye on your compression is a good way to assess the condition of your top-end. Heat and wear gradually reduce the piston-ring and valve seal which keep the pressure in the cylinder causing power loss.Originally Posted by TPEHAK
BUT "you have posted pics of the sludge buildup in your intake tract."
Either way, if you have the engine that far apart (and you have an obsessive personality), IMO... Re-build it.
I have a good question. 2009 Buell XB service manual in the cylinder removing process description does not mention anything about exhaust headers removal and braces between front and rear cylinders removal. It says unscrew rocker box cover, rocker box and cylinder right after engine rotation. No any steps with exhaust headers and braces removing. Should I remove this stuff first before unscrewing cylinders? It looks to me the exhaust headers and braces attached to the cylinders and I can not remove cylinders without removing these parts. I even do not have access to the cylinder head screws without removing the braces.

Yes , Remove all first. Its not rocket science.

I believe that's listed in the pull yer head out ,common sense section.
Your asking too much !
They aren't list in the manual because they expect you to re-engineer all that stuff and build a CAD file for every sub-par Buell junk part you pull off that thing and re-engineer every piece of hardware before you reinstall it. Get busy man.
Katie Perry said titanium is way better, you should build all new parts with that stuff.
