Bike starts up then sounds like it’s redlining

Started my yz125 up today and it idled good for 10-15 seconds then it sounded like the throttle was pinned and I couldn’t get it to stop, and ideas thanks?

Air leak in intake boot, base or head gasket, or crank seals. Rpms should change when you spray carb cleaner on the leak

Thanks for the help I don’t have a hose clamp on the intake boot so it could be that, I’ll test all the things you listed, thanks
