I start to ride and stop again and repeat the same issue.

Right now I have to settle for the bike to hang the revs high for a while and if the light last long enough it will eventually (But taking its sweet time) go back to 1700rpm.. It also does this weird thing that once it has passed enough time it will idle high again completely on its own..

Ex:
>I stop for a light put on Neutral or Pull the clutch bike revs high on the low 2000s RPMs.
20 seconds pass
>Bike idles back down on its own to 1700rpms (My desired idle speed)
10-15 seconds pass
>Bike starts to idle high again to 2000s RPMs without me touching anything.
Rinse and repeat for as long as I am stopped.

This is the really the only issue I have at the moment.

Also I am running NGK DR8EA (7162) Plug which is what the manufacturer recommends, should I switch plug now that I have the mods?
Forget about your plug, and forget about your "mods", they are not relevant in this situation. You have changed your life by 1.22 cubic inches. That is not enough to factor in and everyone here has done the exhaust and cone filter thing. That is why we have a base line of jet sizes and adjustments to apply to the CG platform.

That carb is a tube with a slide to block the air and two holes to control the fuel flow. Those holes don't change. They certainly don't change randomly while you sit on the bike. The idle screw does not move in and out on its own either.

I do know one thing that will cause your symptoms.

Your air/fuel mixture screw has a fine point that closes the pilot jet when it is fully screwed in. It is a very delicate point and can be damaged if the adjustment screw is turned in too hard. It is easy to damage the point if you turn the screw in and out several times, going to full in, then turning out the desired number of turns from closed. I think you have made that trip several time now.

It also has a tiny spring to keep it from vibrating and changing the setting constantly, It can be mashed and become useless if tightened too hard,,,,, and that is the problem you seem to have.

I would check that A/F screw tip and spring.

Past that I am clean out of ideas.
