Some of our customers complain about poor low RPM fueling, stalling, as well as a very snatchy on-off throttle response. Luckily there are a few things you can do that will make the bike run much better, give it more power/torque, and make it much easier to rider. An aftermarket ECU (best option) or EFI Controller is the best way to get your CRF450L/RL to run properly, and also increase power and torque. We use the Vortex ECU on our CRF450L/RL Project Bikes... Vortex X10 ECU GET RX1 Pro ECU JD Jetting Power Surge 6X EFI Controller And to improve performance even more, save some weight, plus make the bike sound better, add an aftermarket exhaust system from the CRF450X...

Steahly Flywheel Weight Twin Air Power Flow Filter Kit Twin Air air filter Doing these couple of things to the bike will make it run much better, help get rid of the snatchy throttle, and improve performance substantially compared to stock. It will also drop about 8-9 lbs in weight, plus the bike will obviously sound much better if you do an aftermarket exhaust system. ** NOTE: Yoshimura, Graves Motorsports, FMF Exhaust Systems, Vortex ECU's, and other performance products, are designed for closed course competition use only.
