 I didn't mean to stray in my last post, I was trying to find a correlation between 5.5oz and 213cc, but..... I *may* have it now...
...in the 'BSA book by OCEE RITCH' from 1970, Page 117 says to effect 'the A50/65's take 190cc (so I may have been right there *smile*) , up to '52 takes 142cc in the forks, and after that up to '66 they all take 213cc '.....if I recall, Richard L also has a copy of this book
 
 I'll attempt to take a pic of it and add it when my phone stops bouncing down the driveway.... *eek*

Manual said 213cc per fork....interestingly, it says this equates to 5.5 fl.oz....but I used a conversion App. and this say 5.5 oz (UK) equates to 156 ml.
Is this a typo or are my calculations inaccurate?

213 cc = 7.5 (UK) fl oz
or
7.2 (US) fl oz.

I think I suggested that...but was *guessing*

 Here's a pic of the paragraph from Ocee Ritch; phone didn't bounce- this time ... *eek*

maybe the wikipedia page on weights and measure could be replaced with one about BSA fork seals? then order will be returned.

I have a new question, I think, in this topic. Are fork seal holders available in flared and straight versions to accommodate gaitors vs. shrouds, respectively? Otherwise, are they all flared so that the flare centers the seal holder in the shroud? I seem to see both types online, but it seems they are all called 29-5310.

Thanks,

Richard L.

Well, just called Draganfly and, according to them, they're all flared.

a question Uncle D, is the oil leaking past the seal and up the stanchion, or is it leaking past the threaded seal holder? there is known issues with leaks past the threaded seal holder which you can read up on old threads, and naturally this isn't such an issue compared to the seals themselves, albeit dripping on the floor!
