sounds like your running lean? i had a similar problem and that is what it was.

Try checking the roll over sensor under the hood, it may have come loose and is bouncing around.

it dosnt cut off when i hit whoops tho it only the low rpm landing its like after i let off the throttle the rpm just sink the landings are smooth untill the bike dies it as soon as i touch the ground the bike dosnt die in the air eather only after i make contact then its like trying to pop start it

The roll over sw would be my 1st thought as well.
Although what do you have done to it ?
Numerous things can do what your refering to.


By the way I and many others have a way to fix the roll over sw.
If you havent had one apart, there is a small well call it counter balance looking shaft that rotates when the quad moves around.
Very easily could that be shutting the fuel off when your jumping,we have had them shut off just riding on a small off camber .
