Besides 'too fast'.....can anyone guess what RPM this unlucky engine achieves?

The speed may be ok for that engine.
Many of the twins run at 1000 rpm.

My twin is rated for 1000 rpm even though I run it at about 800.

That engine in the video didn't sound bad to me.

I thought at a couple points in the video it was turning excessively fast, over 1000. Maybe not.

More examples of overspeed?
In this video at 1.00 and at 3:10 the 2 big engines seem to be running quite fast.

Looks and sounds like a 1000 rpm twin at the rated rpm

The flywheels are 5 feet tall.
