In the last part we started making a pressure regulator, allowing us to
increase the pressure of the oil in the return line after the
T joint where the small oilline goes to the cylinder head. The
more resistance in the return line, the more oil goes to the
head. The plan is to find the optimal setting, measure the gap
under the adjusting bolt and then machine a ring to fix the
adjuster in that position.
The oilline in front of the frametube is connected to the crankcase
breather by the way, something else we will need to fix as it
blows a bit of oil when the motor is running.
