Description:
The 70 twin gas is the littlest bicyilinder of the big Aviomac family.
This is a 70cc 2-Stroke Gasoline/Oil bicylinder which operates in the “Boxer Style” system with opposed cylinders that fire simultaneously for more power, ideal balance and greatly absence of vibrations, that normally are present in other engines.
To elevate these excellences, the crankshaft has been totally obtained from a whole steel bulk and the connecting rods are obtained from ergal and made by utilizing CNC machinery and precision castings.
All of this is supported by aerospace quality ball bearings with high smoothness.
The chromium-plated cylinders use dual-ring pistons which guarantee considerable performances.
The alimentation is supplied by a reed block valve and by a very reliable Walbro carburettor.
