Took apart carb cleaned and now there is no mid or high range

I have a 1998 1200 custom i took apart the carb and cleaned it out, before i cleaned it it ran fine. now it ildes fine but there is no mid or high range. i checked the float and accelerator pump and that seems to be fine. cleaned the ilde and main jet and they are clean there is one more jet in the carb that seems to be clogged but im not sure. when you start it up and run it without the air cleaner and put you finger over the two little jets in the lower part of the carb and hit the throttle at the same time it runs great but will not idle. when you rev it up it will die please help erick

Did u install new gaskets, the engine might be sucking air from outside the carbs. u can use a propane torch (not light) spray a little around outside of the carbs, see if engine sounds different, if it does... leaky gasket.. u might check there is no unplugged vaccum hose.

1. check for an intake leak in front of the carb, like broke carb gromet, carb flange o'ring/gasket leaking, or any broken or leaking vacuum lines. If the bike has been sitting for a while or has had little use, the carb is probably plugged up and needs cleaning.

Bike loses power in the mid rpm range

Try the air filter first (make sure it's clean). The needle valve on your carb slider could be bent, or not seated correctly or just set wrong. If you have a power exhaust valve, it could be set wrong or malfunctioning as well. Good luck.
