Help a brother out...

All,
What's up I am Jared.
First of all I am a rook at this forum business.

I recently got my bike back from Japan, while stationed there I had my bike tuned to pass emissions but it failed the tests. During this time I had bought a PCV to help the tuner. When I got my bike back on the first ride it would not Rev above 8k with a load. I searched all kinds of forums, took it to a dyno make sure it was the tune, changed spark plugs. Checked my tps with the pc, and finally I realized that it was the EXUP valve that wasn't opening during riding. I unplugged the servo so it would just stay open but would like to fix the issue.

My question is what would cause the valve to not open a 6k. Like it is supposed to?

Thanks for everyones help in advance.
