levers

I need a better brake lever and perch for my CB72. I think some of the lack of braking power ( I have V.Brake linings already)is from the perch itself flexing when I pull on the brakes. The old Hawk stuff was very lightweight. Has anyone used any modern dirtbike stuff, like those folding levers, etc? Most ones I saw are for disk brakes and if I use a clutch one upside down the lever will fold the wrong way. I did see one for an XR50 minibike that was a drum so maybe that would work. Any thoughts?

Thanks, Chris
