My stock sv master seems to work just fine with twin line set up , but i have to change calipers back to 05 radial + 5mm spacer ,or go to 320 rotors (sv1000 310mm)as i just found out today. I have 08 calipers on 04/05 600 forks , pads are overlapping outside of rotor by 5mm

damn

I have a set of 05 600 gold calipers but i think i will change out to a larger rotors
