[2] BUILT-IN DYNAMIC BALANCER (BALANCER MODEL ONLY)

Engine are sure to vibrate by piston's reciprocation.
Theoretically, three-cylinder engines are much less
prone to cause vibration than four-cylinder ones (second
inertia, etc.). However, any engine has many moving
parts in addition to its pistons and cannot be completely
free from vibration.
The four cylinders engine can be fitted with balance
weight on crankcase to absorb the second inertia
mentioned above and reduce vibration.
This engine is internally provide with two balancers
(1), one at the suction side and the other at the exhaust
side.
