The irony here in some ways, when talking about building Norton’s in China and the poor quality we often see coming from China, is that Donington definitely demonstrated the ability to build to a high quality standard.
When I bought my 961 I fully expected, and intended, to have to change the coils and relays etc. But to the best of my ability, comparing what was fitted to the bike, to the pictures and explanations I could find, they were all genuine Bosch.
I also intended to go through the wiring and apply dielectric grease to all the connectors and re-route any poorly routed wires etc. But all the connectors were greased from the factory, and I couldn’t fault any of the wiring routing.
I never found a loose fastener on the bike either. Or an oil leak.
Furthermore, my bike never had any of the running or idling or oil in the airbox issues suffered by many.
So, they could do it...
