Thanks guys.
As I recall the SR was running when it was parked. My dad had too many other projects and the bikes ended up being pushed into the corners of the barn. I was busy with my own collection of early '70s (non-BSA) race bikes at the time. Since then I've sold almost all of my collection. Now I have another.
The SR turns over and has good compression. Cosmetics are rough though. It's my first pre-unit project though so I'm sure I'll run into some surprises. I have a couple of relatively easy projects underway (Royal Star and Thunderbolt), a couple of "challenging" projects started (Square 4 and Sunbeam), and I'm hoping the SR will be somewhere in between both in time and $.

Thanks for the link to the service sheets.
As soon as I get a good pic I'll post it.
Cheers,
Terry
