Ok a question about oil, again this is prompted by my Triumph 3TA from 1962 but it could apply to a good few bikes I suppose.
According to my book.
Engine oil is SAE 20 or 30
Gearbox is SAE 50
Primary Chaincase is SAE 20
Does a modern 20/50 do it all or do you use two different oils ?
‘Similar’ questions have come up before, the reason I’m asking is I’ve used a Classic Vehicle 20/50 for everything but selecting 1st gear is a bit ‘noisy’ changing up and down is then ok.
I’ve inspected the clutch which though not perfect seems ok. It was dragging if I had the bike running on the stand but trueing the pressure plate seems to have resolved that.
Is it the oil causing a graunch when selecting 1st (sometimes it’s just a clunk)
I don’t mind tackling the gearbox but … if it just the wrong oil it’s a bit of overkill.
The Classic Vehicle oil looks very much like Duckhams Q 20/50 by the way.
