2002 Honda XR200 dies when I rev it high

[offroad adventure]

I just bought a 2002 Honda XR200 that was hardly ridden at all and has lived most of its life in a storage locker. I already cleaned the carburetor and replaced some of the jets. I also replaced the air filter. I have checked to make sure the pep cock is clean, and even replaced the gasket that goes between the exhaust pipe and the engine. 

It starts up on the first kick, but when I turn the throttle more than 1/4 the way, it dies.

Any ideas that you have would be appreciated. Thank you.

Sounds like the needle is not in correctly, and is not moving correctly

Did you ream the passge for the main jet?  Is the float height set to factory specs ?
