John, I was wondering how well the water jacket was going to drain myself,
as it’s still freezing here at night. I’ll have to remember that trick of turning
it upside down. What you say about the "air space" in the water jacket
makes good sense.
I’ll have to take a look and see if the water outlet of the cylinder is
lower than the rear gas tank mount bolt hole, as that’s drilled into
the water jacket. If the mount hole is higher, it might be a fun
experiment to leave the mount bolt out and plug the water outlet
to see if the "hot spot" in the cylinder goes away.
Prepare to be boarded!
