YZ 125 bogs with full trottle

Today i tried a 2002 (or 2001?) YZ 125. When I drove slowly with just alittle trottle, it seemed to run well. But when I gave it full trottle under acceleration, it bogged out after 2-3 sec and it would stop if we continue to give it full trottle. When it has stopped, it is no problem to start it again.
We took the carburetor apart, and cleaned it.
It has a 480 main jeg, but we tried a 400 jet with same result.
I didn't measure the float height, but it seemed to close the fuel when it was in horisontally position.
Any tips?

Yes it worked! Thanks.

I lowered the float height a bit, and it seem to run well now. But how do you measure the correct height? The manual tell you to use a tool with a transparent tube outside the carb and measure the gas level. And I have not this tool.
