A10 Timing

[DAVE BRADY]

Hi,

Interesting.  Both A10s, a '59 Flash and a late SR, I had in the past had the larger hole fitted to the exhaust banjo and My wife's '51 Flash has the larger hole one fitted as well.  Perhaps there was a spate of owners fitting them as it was considered a worthwhile mod??

I think it is/was quite common.
