In building the Tarantula Performance Racing project YFZ450R, we encountered several common obstacles in prepping the new Yamaha for pure racing applications. A lot of new Yamaha owners have to find solutions on their own for some of these tasks, so we thought we would alleviate some stress for YFZ-R owners by periodically posting one of the solutions we came up with to prep the YFZ-R for motocross.
Every YFZ-R owner who wants to improve performance with an exhaust or airbox modification, and do it the right way, will have to install a fuel management interface. After installing our Motoworks FMI, we took a block of high-density impact foam, sliced it partially open and carved a pocket the depth and width of the FMI box, about 2 inches by 3 inches. We then adhered the velcro to the foam and the quad's plastic beneath the seat. We used the velcro to anchor the foam to the plastic, and the foam provides a secure, protective space for the FMI.
We mounted the TPR project YFZR Motoworks FMI tuner in the pocket where the factory toolkit is located.
Our FMI stays put even during the hard impacts dealt on the motocross track. And we can easily remove the foam during maintenance thanks to the velcro. We did not waterproof our Motoworks FMI because we didn't think we would need to just racing the quad only on motocross tracks, but if we tackle that we'll be sure to post how we did it. With the cost of the foam and a little duct tape for peace of mind, our first tip protects our Motoworks FMI for a cost of about $2.
Stay tuned for more tips on the new Yamaha YFZ450R.
