Idling a Jawa 350 twin

Slo mo video of the rare motorcycle - Jawa 350 twin. Notice the firing doesn't have any particular order.
It is a twin cylinder single carb two stroke motor.
The Yezdi factory shut down before too many bikes were sold. Running these bikes on road now is a problem becuase of huge oil smoke that' it emits from its twin pipe.
Not to be compared to the legendary RD350, this was a sedate, silent cruiser.
