Mine dont. The one on the right closes after the left one. Then after its closed it opens for a bit(very shortly) when the other one is closed. Weirdest thing I've ever seen.

:thumbsup:

The auto-decompressor disengages at around 900 rpm. At any rpm level below that, it holds one of theexhaust valves slightly open to ease starting. But you already knew that... :ride:
