Motorcycles > Yamaha FZ-09
This is my Yamaha FZ-09 sportbike. With the FZ-09, Yamaha positioned a new high-performance three-cylinder 847cc engine in a lightweight platform, creating a quick-turning motorcycle with an impressive power-to-weight ratio, stump-pulling torque, and street-friendly ergonomics.

GP Suspension kit (new valves and needle, new springs) installed in the front forks by Stoltec Moto and GP Suspensions.
I removed the forks and shipped them to Stoltec Moto for installation.

EJK Electronic Fuel Kit
I could have been completely happy with the throttle response acheived with the ECU Reflash. It's amazing what improvement can be acheived without even changing the fuel mapping; one change alone--keeping the injectors on during deacceleration--seems to have made a big difference.
But I wanted to try some fuel changes with the EJK fuel kit to test the results. The biggest benefit, I think, is a slightly improved smoothness from closed to open throttle and a much bigger improvement during acceleration. The EJK is load-based and easy to adjust. Just push buttons to add (or subtract) fuel in either cruise mode, acceleration mode, or WOT (wide open throttle).
Graves Block Off Plates
While installing the EJK fuel kit, I installed the Graves Block-Off Plates. See the Graves website for photos.
Fabbri Windscreen for FZ-09
This Italian windscreen works well to keep the bugs off the instruments and provides just a hint of wind protection sufficient for summer riding. The asymetrical shape is really cool (shown in satin black).
Rizoma Tail Light for FZ-09
The below image is just to show the difference between the svelte Rizoma tail light and the stock appendage.
Rizoma Action Signals for FZ-09
I installed these signals front and back. I used two pair of OEM turn signal connectors and an LED flasher relay (to prevent fast blink rate caused by the low LED voltage) from CustomLED.
The wiring was a bit tricky, so I thought I'd post the routing to help others with the job.
