I have an 07 WR450 that I installed an Edelbrock carb. on. Yes it works very well!!!One of the best mods I have done to the bike. With the Edelbrock you unplug the TPS and don't use it. There was a post where someone did an actual dyno run showing the TPS plugged in and not plugged in. Does anyone have a link to it. I believe it showed the motor making more HP with the TPS unplugged.
