Sometimes when I start the bike it revs to like 5k and stays there for a while or until I start riding. When riding it will sometimes stay at 3k with out me touching the throttle or sometimes if I don't touch the throttle it will slow down and just shut off.

My guess is that your choke is stuck, but have you adjusted your ideal
screw? It's positioned under the petcock on the left side.

Certain sign of carbs needing cleaning ... , to eliminate doubt . First check tank and carb venting ... petcock for obstruction , fuel lines for collapsing .. fuel flow from petcock ..., My bet would be dirty carbs ....,
