14. FURTHER RETARDATION

The '78 CX's standard,ie small 240mm diameter,front brake rotors with their single pot calipers are certainly showing their age so it's time for an upgrade.
Turns out that Honda's '82 CB650 Custom came out with an almost  300mm rotor which just happens to bolt right up.
Couple that with an ex BMW K100 4 pot Brembo caliper & job done......well almost.
Two things holding up progress, the caliper has to be adapted to the Suzuki forks and the disc needs spacing away from the wheel.
But first of all the wheel bearings are 15mm I.d. but the Moto Guzzi  axle needs ones of 20mm I.d.
Luckily I had a spare set so time to fire up the heat gun again then to 'drift' (which is a euphemism for smack the hell out of) ,them out.

That done it was once more to the lathe to turn up a couple of ali axle spacers & a  stainless steel spacer plate for the disc.
