Also are you running a fuel filter b/t tank and carb? Your tank could have crud in it, thus clogging the pilot after each cleaning.

You never mentioned adjusting your fuel screw at all. If it is all the way in, it will probably be lean at idle regardless of the pilot jet size. Count how many turns out the fuel screw is set and record it, then start adjusting it. I would set the fuel screw at about 1-1.5 turns out to start and adjust from there. Also, make sure the fuel screw is installed properly, in the proper order. It should be O-ring, washer, spring, screw.

Punctuation is your friend, by the way. That was very difficult to read.
YES!!...without it you are hard to understand...and I'm sure you are smarter than no punctuation makes you appear.

Save yourself some aggravation and screw a new one in there, and set your fuel screw to 2.0 turns out, and see how it runs.

Fuel Screw/Pilot Jet
Fuel screw settings in the 'book' are recommended starting points. Every bike is different, as is the temp and altitude. Set the screw according to this method. Do it with the bike fully heated up.
Gently turn the screw all the way in. Now back it out two turns. Start the bike and fully warm it up, go for a 10 minute ride. Set the idle to speed to 1,500~1,800 RPM as best you can (I know, without a tach this is tough, just set it to were it idles relatively smoothly). Once warmed, slow the idle to the lowest possible speed.
*** When turning the fuel screw, keep an accurate 'count' of the amount you are turning it and record it in case you have to reset it for some reason. Makes life easier when you can just set it from notes Vs. going through the procedure again.***
Turn the screw in until the idle becomes rough or the bike stalls.
if it stalled, open the screw about 1/4 more turn. Restart it and slowly screw it in till you can just perceive a change.
If the screw can be turned all the way in and the bike still idles perfectly and does not stall, then you need to go down a size in pilot jet.
Now very slowly, open the fuel screw till the idle is smooth. Blip the throttle, let the bike return to an idle, wait say ten seconds. Confirm it is the same smooth idle.
If the screw has to be opened more than 3 turns to get a smooth idle, you need to go up a size in pilot jet.
If you find it does not stall with the larger jet but has to be open more than three turns with the smaller pilot jet, put the larger one in and set the fuel screw at 1/2 turn.
If the idle speed increased, adjust the idle speed knob to return the bike to a real slow idle speed. You must then re-visit the fuel screw. Keep doing this till the fuel screw is opened just enough to provide a nice steady idle at the lowest possible RPM. Once this is done, increase the idle speed to the normal one for your bike, typically about 1,850 rpm, but go by the spec in your manual.

Clean the passage above it.
Clean and lube your choke plunger
Replace your fuel screw o-ring
Change your plug
Clean you plug lead connection.
PROPERLY adjust your fuel screw.
