This is a simple task, and involves un-plugging the EXUP Servo motor. Graves Motorsports offers an EXUP Servo Eliminator which plugs right in so you're bikes computer won't realize you've removed anything. This optional part is highly recommended anytime you remove the OEM exhaust. Choose the option if you want it to be included as part of the package. Graves Part #: ELY-U-EX ** OPTIONAL: Graves AIS Block Off Kit: (adds to package price) When installing an aftermarket exhaust on your WR250R/X, the AIS (Air Induction System) is no longer serving any purpose and will cause backfiring/popping on deceleration. Once you remove the AIS from the bike, this kit can be used to block off the port/hose on the bike. Choose the option if you want it to be included as part of the package. Graves Part #: ABY-08WR2-S ** OPTIONAL: EFI Controller: (adds to package price) An EFI (Electronic Fuel Injection) Controller is HIGHLY recommended any time you install an aftermarket exhaust and/or air filter on your fuel injected bike, otherwise you will see little to no performance gains, and the bike may even run poorly. At this time, we offer a couple different EFI options, the JD Jetting EFI Controller, or the Dynojet PowerCommander V. Details below. Each are simple to install and plug into existing wiring using stock connectors. Choose the option if you want one to be included as part of the package.
