I’ve now become the owner of a Nc30 and NC35 in the matter of a few weeks .... both bikes have been butchered at the front however I have pretty much a complete NC30 front end ( clocks/ lights/ fairings)
Will this translate across to the 35 ?

Is one of the bikes going to be spares for the other?

clocks, lights and fairings are not a straight swap.

Clocks need different pickups for the tacho.
Front mounting is different for clocks and fairings
top fairing mounts differently

You either need the clocks to match the motor or to change the pickups to match the clocks in the motor
