I want to shift my weight further back so i can get to the BP on my pocketbike. I tryed screwing like BMX pegs onto the back axel but they didnt fit. So on the frame like acouple inches up from the axel do you think i could drill a hole. Its a flat square framing about an inch thick. But its hollow. I am 165 pounds. If i rigged this do you think it would warp,crack, or cause damage to the frame?
