Toddy a friend from the Dirty Bobbers forum has recommended cutting the ports at the top of the brake plate and doing a frame with mesh. Considering that Toddy is a top builder with loads of experience I will take the recommendation. However I may not do stainless as Toddy did on his SR500 Café Racer build. But it may depend on what materials fall to hand when I get to the bit of work.
