Nor is it the too large master cylinders. On my RD350, that has the same 2x48 mm piston caliper as the 72-76 XS/ TX models, a 13 mm Brembo master cylinder improved brake effort and control a significant amount (The RD MC was 5/8")I like originality but when it comes to brakes I use the thing best available.
IMHO that ain't rubber brake lines.
