Why do the Revs stay high when the throttle is open?
When I open the throttle and let it close again the revs stay high.. it doesn’t always do it and to get the revs back down I have to either wait for about 10+ seconds or blip the throttle again which sometimes helps but sometimes puts the revs higher. The carb has been stripped and cleaned.
Why does my car rev up when idling?

What does it mean when your car Idles too fast?
But if the accelerated idle persists even after the engine is fully warmed up, it probably indicates a genuine problem. Troubleshooting Fast Idle Problems The first step is to determine if there are any diagnostic trouble codes stored in the PCM (powertrain control module).
Why is the idle speed too high after start up?
The high idle after start up is one of Toyota’s way of reducing emission. A warm engine emits less emission than a cold one so Toyota and other manufacturers put in this feature to help get the engine to operating temperature quicker and thus reducing the higher emission that would have been emitted if the engine was still running cold.
Why does my car Rev by itself when idle?
It sounds like you may have a dirty or failing idle air control valve. The idle air control valve monitors the air intake as it is mixed with fuel prior to being injected into the engine at low speeds and at idle.

Why does my bike not rev to higher RPMs?
Since you cannot go above 1300 rpm, that rules out your TCI ignition not advancing, as a cause of your problem. This points to the carbs as likely suspects. You said the bike sat for a year. When was the last known time that you were able to rev the engine to higher rpms?
What does blip throttle and Revs hang mean?
Blip throttle and revs hang = rich/lean? are adjusted towards the lean side. If on the other hand a quick blip returning to the idle rpm the bike is running a little rich. Does anyone know of the underlying mechanism to this analysis?
Why does my bike engine not rev up?
You can have fuel in the pilot circuit but if the air supply is blocked off, then engine would not rev up. On my carbs, the pilot jet air comes in through a hole at the carb front, goes down through a hole in the bowl gasket, along a passageway, and mixes with the pilot jet in the bowl.
