What i like about old British bikes is that i can fiddle with them on a rainy day. I always liked repairing old bikes and cars since i was 13. My new bikes needed very little work and just maintenance. Never used a main dealer for servicing etc. I just ride the new bike away and do any work. That means i have no warranty but have been lucky. The first year is covered but second year is not as it appears it has not been back for service.
Worst problem with the new bikes is engine management light. Both my new bikes have a warning but ride alright so i leave it running
