Adjusting Pickup height on a Dinky DK2 HSS configuration (Seymour Duncan)

[jalexquijano]

I own a Jackson Dinky DK2 made in Japan which came with stock JB TB-4 humbucker and 2 STK-1 Single Coils. Whenever i strike a power chord hard, i can hear a loud noise produced as if the strings were hitting the pickup pole pieces. Should I lower all the pickups? Is there a standard measurement for the pickup height in this guitar? If so, can someone provide me with the corresponding measurements for each pickup?
