Enter this title to see an interesting video of an outback expedition in Western Australia wherein BSA side valves figure prominently.
Nice old Land Rovers too.
I was on that ride. There was 4 WM20s,a741 Indian,a20s Indian and a Norton plus 2 tele fork M21s.They took 4 days when a 4WD would take 2 days. No real problems with the bikes. The 741 had a drink of water when it went down in a puddle. the Norton maggy got wet and an M21 had 1/3 of the bead popped off the rim and locked the back wheel up. All were fixed and none ended on the trailer.A medical man rode in one of the Landys in case of a spill. There is talk of a similar in 2023

The youngest was 30 and Greg on a tele fork M21 was 72. The rest were in there 50s and 60s. It took a few weeks to get over it but they are all keen to have another go.
