STM clutch help !!

So i have the new STM rage 3 clutch set up, i finally have got my cam arm weight tuned in for the most part,but the problem I am having is when I take off from a dead stop I get this jerking when I first ease into the throttle and then it goes away !! My motor mount are good Ive tried different belts cuz I thought it might of had a flat spot but still continues to do it! any help or input would be greatly appreciated.
Thanks in advance!!
