Those forks look awesome, But I agree on the strength issue. You may just be able to slide some thicker pipe inside those for strength.
I've found that black iron pipe is plenty strong for go carts and minibikes. I helped my friend build one from black pipe, Pretty solid bike, but the forks do flex a tiny bit when going down the road. A few gussets would fix that though.
