Description
The ZDZ 97RV-J is a two stroke, 97ccm class-gas engine with processor controlled ignition unit. This engine is based on the ZDZ 90RV-J , but it has many modifications including a new improved design with CNC machined crankcase and backplate to decrease vibrations and increase power. At the same time, we were able to keep the same outer installation envelope from the ZDZ 90RV-J.
Fuel intake of this engine is managed by a rotary valve which allows for more precise control over the timing, unlike the usual reed valve system.
