The idle circuit is plugged up. ALWAYS have a fire extinguisher on hand when working on carburetors.
Remove the water trap bowl at the bottom of the petcock, (gas valve). Is there any water or trash in the bowl? Drain a cup of gas from the tank. Is there any water or trash in the cup? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ).

Drain the carburetor and remove the carburetor from the engine. Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Remove the idle screw and the air screw on the outside throat of the carb and spray into the screw holes as well. Pay special attention to the pilot jet area.
< < READ CLOSELY > >
Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two adjusters down. Only screw these in until they LIGHTLY seat. Now turn each adjuster one and one half turns outward. Put the rest of the
carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. This process should get you back on the road. A “very helpful” rating for this answer? Thanks!

It's probably running out of fuel. You probably have a plugged line, filter or screen somewhere. When it sets a while the gas slowly seeps into the bowl and when you start it up after sitting it just runs till it runs out of gas RPM's slowly building as it is running out of gas

I guess youwillhaveto adjust the clutch cable so as to open the plates more at the pressure plates to let the clutch plate rotate freely instead of binding thus the low rpm.

You have upset the air fuel flow by changing the exhaust, I would try placing a piece of paper over the air filter to change the intake first, to see what happens, then if that doesn't work, you will need to rejet, and sometimes the factory setting won't work, so you will need an adj jet, Find an aftermarket for your carb I think dyno tune has one. They work great. I hope this helps.
