Wheelie bog

[zr900turbo]

Hi
I have a 2014 m8000 with a boondocker tial turbo IC.
When i run on the flats ITS not bugging at all. But when i start to wheelie it can start bugging hard.
Anybody have any clue what may be causing this problem?

The front smart valve in the tank might be bad. Could be sucking air when your skis are up
