You've sort of answered your own question really. It's a bitsa that has evolved over 56 years. Maybe Triumph didn't do this but someone else did. Maybe the tank was from a twin carbed bike or the bike it was created for ran better with this set-up. I had a bike which only ran at its very best when the tank was over half full.
