Spent the winter restoring a 1977 RD400E.
Still some carb work to do, but otherwise ready to roll.
Brings back sweet memories from my late teens when I bought my first new bike, a 1977 RD400D.

Yes,
My original '77 back in the day was a D model.
In Canada, the E's arrived the tail end of '77.

Correct, 77 model year is a D and 78 model year is an E.
In North America each model year is manufactured in the end of the previous year, usually between August and about November or December. So, the RD400C models were manufactured at the end of 1975, RD400Ds were made at the end of 1976, and so on. And a'78 model for example would be made between about August and November of 1977.
The US model RD400F 2V0 was manufactured a little later than normal (November 78 through January 79), likely due to the EPA certification and regulatory items that model had to go through, but I'm not 100% sure why the build dates for the US Daytona are later than other models.

To my knowledge all North American '78 models were Crystal Silver.
