DescriptionThe whole story▼
The FZ8 was Yamaha's attempt at an accessible middleweight four, built on a detuned R1 engine and sold for five years. The survivors are cheap, solid and modified freely, and the secondary air system is one of the standard things to remove.
Key Features
- Covers FZ8 and FZ8 Fazer, 2011–2015
- Bypasses the PAIR solenoid circuit electronically
- Valve, hoses and reed valves can be removed
- Plug-and-play on the factory connector
- No remapping and no diagnostic reset
- Fully reversible
An Underrated Engine
The FZ8's 779 cc four came from the R1 with milder cams and a shorter stroke, and it is a genuinely good motor that has never been fashionable. That is why these bikes are worked on by owners who like them rather than by people chasing a name, and why sensible, cheap modifications get done properly.
The Overrun Noise
An inline four with an aftermarket can crackles hard on a closed throttle, and most of that is the secondary air system feeding fresh air into a hot exhaust. Take the system off and the crackle mostly goes with it. Whether that is what you want depends entirely on why you fitted the exhaust.
Unplugging Alone Fails
The ECU energises the solenoid coil and checks that it responds. Pull the plug and the diagnostics log an open circuit within seconds and light the dash. This part reproduces the coil electrically so the check passes and the hardware can leave permanently.
