In the interests of factual accuracy the oil change frequency for the primary drive in pre-unit Triumphs is every 1,000 miles, per the owners handbook. The interval for changing the engine oil and primary chaincase oil on a T140V is 1,500 miles, again from the owners handbook, hardly a lot more frequent (other than in percentage terms before some other pedant butts in). And I get accused of exaggeration! Anyway, what's wrong with a bit of hyperbole? Oh, and the reason Triumph switched to breathing through the primary chaincase was to improve its efficiency and reduce leaks, rather like the original Continental GT which was the only 250cc RE with a decent breathing system. The vast majority of those who know Triumphs reckon that the post 1968 are the best, particularly the 1969 or 1970 models. These of course had the breather exiting from the primary chaincase. Don't you just hate didactic posters?
