CARBURETTOR Problems In Low RPMs
#5
There's loads of things that could cause this effect unfortunately. It's just a process of elimination one at a time.
Bit confusing the way you described that the bike is running oppositely now to when you first had issues before carb cleaning though.


Firstly you've not mentioned the air filter at all, when was it last changed and what type/brand do you have?
If the bike can't breathe properly then it will affect the idle and lower revs, but can also hold you back at higher revs if it's particularly dirty.
Have you even looked into the airbox, it could be clogged up with emulsified oil as well, which my bike has had before.


As mentioned are the HT leads and caps okay?
You can trim the ends off the HT leads by 5-10mm, and maybe try new plug caps. Don't bother with new OEM ones as the price will make you fall over, but a lot of us have replaced them with NGK ones which work fine and are a great price.

A carb balance by the way will only work well when everything else is running properly.
So if your air filter is clogged (or you have an air leak), your TPS is breaking down or knackered, or your spark plug caps are on their way out then a carb balance will be irrelevant and can even make things worse.
Even the TPS positioned wrongly can make the bike feel a tad jerky at lower revs, i would do a check on that too, i'm on my 4th one now although this time i bought a brand new one at a much lower price than over here from Germany as it was all getting a bit silly buying used ones that were at least 13 years old and likely to peg out at any time.

Another small possibility is moisture in the tank, which will sit lower down in the carbs and cause roughness at idle and low revs but once sloshing away at higher speed won't be as noticeable.
