The YGROS ROAD by VAPE is a modern electronic ignition that converts the classic GS/SS electrics to a contemporary system. The version described here works as a 12V AC system with 110 W and static (fixed) ignition timing.
Important: GS160 and GS/4 models with original 6V battery ignition can also be converted to this system - but then not as a "re-use" of the old DC logic, but as a consistent system change to a modern on-board electrical system.
There is an important design difference between the GS160 and GS/4: 1st series with a small cone (Ø19 mm) and 2nd series with a larger cone (Ø21 mm). The 21 mm cone corresponds to the level of the SS180 and is considered the more stable base.
Note: For mixed components (engine/polewheel/cone), always check the fit and flash the ignition timing after installation.
Regardless of the system selected (AC or DC): A new wiring harness is always required for a clean conversion. The original 6V electrics are not designed for a centralized regulator system - and in most vehicles, the cables are also brittle due to age, corroded or have already been repaired several times.
Note: For GS160/GS/4, please also check the cone type (Ø19/Ø21). The electrical conversion is always carried out with a new wiring harness.
YGROS ROAD by VAPE consistently modernizes the GS160 and SS180 to a contemporary system. GS160/GS/4 with battery ignition can also be converted - then as a complete change to a new on-board electrical system. A new wiring harness is always mandatory, regardless of whether you use AC or an optional DC solution. If you are overhauling a 1st series GS160/GS/4 engine and replacing the crankshaft, switching to the 2nd series type (Ø21 mm cone, needle bearing on the connecting rod) generally provides a more stable basis.
