My carb cleaning process is the following:
1) disassemble
2) soak in carburetor cleaner for 20 min
3) run the agitator for 5 min
4) rinse
5) dry with compressed air
6) assemble with new jet components
First, please, please, PLEASE do not think that this process is in any way whatever of any value, except to fool you into thinking that the carbs are "clean" and that you can eliminate them from whatever problem you may incur. While it is indeed possible that this might be fine, there is zero certainty that it will be. The only way to know with certainty that the carbs will function properly is to inspect each and every passageway by seeing a clean and sharp stream of carb cleaner pass through it. There are more threads on this very forum than I can count that have gone on for endless pages searching for some mystery problem that couldn't be the carbs because they were "(already personally, carefully, professionally, ultrasonically, etc) cleaned", only to find out at the end that they really were not.
Secondly, do not replace ANY parts in your carbs unless they are actually damaged somehow. If you have rebuild kits, take out the gaskets and throw everything else away. That means any jets, needles etc.
I could not even guess how many bikes have come into my shop to be repaired that "couldn't be the carbs 'cause I just had them professionally cleaned by the dealer" etc. that simply needed the carbs cleaned. Nearly as common, is "rebuilt" carbs with "brand new carb kits with all new brass" with mystery running issues. Take carbs apart, clean them, and replace all the "new" jets and needles with "old wore out FACTORY OEM parts" from my stash of junk carbs and by some miracle, the bike runs flawlessly.
FWIW, I actually have one of these bikes, and it is a particular favorite! Best sounding engine in any vehicle ever made (IMHO) or at least that I have heard, and I have been around a lot longer than the bike so I have heard quite a few!
