Default Slide spring = Arm pump?

It seems like I'm very susceptable to arm pump on my Gasgas. I feel as though the spring requires more effort at the throttle tube than I'm used to on my other bikes, leading to arm pump. Has anyone else experienced this?

Does anyone change or modify the carb slide spring?

I might change grips from half waffle Progrips to the thicker Rally or Protaper pillow grips to see if it helps.

What are your opinions?
