TRIKE WOBBLES do i have to live with it or is there a cure?

HI i took the trike that i am building out for a test ride today the front end got a severe wobble on, not a tank slapper type,but as if the front end is over sensitive quite violent{hand is sore between thumb and fore finger } is there a cure for this or is it something you get used to. the only other triker in the village mention that he had the same thanks
