Hi

Took HP2 for a spin and noticed a weird fuel starvation problem
If I grab a handful of throttle, the engine sputters and blurp blurps and loss of power
If I ease of the throttle and smoothly and slowly accelerate the engine purrs perfectly and smoothly and power is unaffected

At 120km/h in 6th i need to really add fuel gently and any sudden twist results in blurp blurp stutter stutter
The problem seems less evident in lower gears but grabbing a lot of throttle suddenly brings on the splutter

In all cases easing off and accelerating gently has the bike behaving as normal. In fact the HP2 is running smoother than ever.

The cable operates smoothly without stcking.
in Neutral, cannot recreate the problem (and my neighbors are starting to wish I did find the problem quickly)

Any ideas on what to check next?
