My dad's BSA A10 Golden Flash

[Joolstacho]

Emma, I think you have won a few hearts on our Forum! Great story, and we hope to get a new picture of you in Sweden sitting on dad's bike sometime. (It will always be dad
s bike). But no rush! It's a beautiful ol' machine, take your time with it and enjoy.

G'day again Emma.
What was your dad's name? He may have visited the Forum in the past. Would be best to PM me with that for your privacy reasons.
Don't be in a rush to pretty her up (why do we give bikes a female title). I love the patina.
While your waiting for her to arrive, (6-8 weeks will feel like an eternity) have a good look through the Forum.
Cheers

Hello Emma and welcome aboard, this forum is the best place for helpful, friendly BSA advice.
A couple of things I'd like to ad to the previous replies.

Please google 'dry sump engines', the oil is stored in the oil tank and is pumped to the engine and then pumped back after lubricating the engine. When the motorcycle sits for a period of time the oil will drip into the sump of the engine and create problems when you start it. This is the reason for the drain plug in the alloy sump that Richard posted a picture of. It is much easier to remove the sump plug and drain the oil than remove the original steel sump plate, gauze filter and two gaskets.
To check the engine oil level in the tank it should only be done after running the engine for 10 minutes.

The spanners and sockets used on these machines are imperial sizes known as Whitworth and have fractional numbers. The letters are W, WW or BS. For example, 5/6" WW.

Good luck and I'm so pleased that you have taken on your fathers motorcycle.
