These outside head studs are wet. Drain oil back to the crankcase.
oil comes into the head from above…splits to each rocker…some is sprayed, the rest follows the outer head studs to the crankcase
machined return galleries…each outside headstud
look like this
Copper washers on the outside head studs seal well. Allow securer torque settings.
Kits are available with 4 copper or brass washers and 4 steel ones for the 4 inside head studs.

Or look for 22 x 10.5 x 4. Metric of course.
torque sequence
Don’t forget torque sequence. Diagonally opposed.
Torque in sequence. And in increments.
Don’t go direct to full torque in 1 hit. Take your time.
Clean threads. A little oil. No loctite.
Set torque. Leave the top mount off. Run to warm. Retorque. Test run. Retorque. 70-100 kms. Retorque. Top mount – don’t forget it.
Failure to do this, and check occassionally, leads to cylinder leaks.
Doing this to stop cylinder head leaks? Too late. Do the job properly. New head gasket. While you’re there do the cam chain, front guide, valve seals and valve grind.
Board tracks, loosely based on French velodromes, were popular in the United States in the 20’s and 30’s. Oval courses. Wooden plank surfaces.

The Coliseum Motordome, LA, California, opened April 8, 1910. Built with 4x2in (100x50mm) boards, banked up to 45° (Fulford-by-the-Sea and Culver City both claimed 50°+). By 1915 there were a few tracks operating up to 2 miles (3 km). 24 in 1931.
High maintenance costs, perceived and real dangers killed them.

Reminds me of this Opel Sandracer replica built in Opelwerk Rüsselsheim. I’ve had the luck to ride this-yes, it does go.
opel sand racer replica…13-23 hp…over 40kmh….DM700 in 1922
The thrills of raw speed, banking, overtaking possibility are still suitably exploited in modern racing.
There have been a few nice replica projects documented over recent years.
