The Genuine Buddy 125 old EEC system diagram (2014 and older models) shows the early evaporative emissions control setup used on first-generation Buddy 125 scooters. This system includes the EVAP canister, fuel cut-off (fuel cutting) valve, pressure valve, rubber vacuum and vapor hoses, hose clips, and related mounting hardware. This diagram is used to identify OEM replacement parts for emissions system service, vacuum line repair, and fuel vapor routing maintenance on earlier model years.
The 2014-and-older EEC system relies on a more traditional hose-and-valve layout to manage fuel vapors from the tank and reduce emissions by directing them through the charcoal canister system. Over time, rubber components can degrade, making this system prone to vacuum leaks and vapor flow issues. Common repairs include replacing cracked or collapsed hoses that cause fuel odor or rough running, servicing faulty fuel cut-off valves that disrupt fuel delivery, replacing brittle clips that allow hoses to disconnect, and correcting vacuum routing issues that impact idle stability and emissions performance.
