Just an initial review of the throttle body modification by Injectioneering. After reading various threads regarding this modification, I decided to give Wade a call because the jerky nature of the late model YZ450 made riding it offroad less than ideal. Before the mod I had installed the G2 throttle tamer and the offroad tune. Together they both helped smooth out the whisky throttle response but they only minimized it, not eliminated it. Holding a low speed was still just about impossible. I spoke to Wade and shipped my TB to him. I was planning on being in LA the following week and made plans to meet Wade at his facility to pick up the finished TB and carry it home with me to GA when I flew home. Wade is a very personable guy who clearly knows what he is doing. He explained everything that was done to my TB and the work looked top notch. All machining is done at his shop and there were several other TB's besides mine that had been completed. There are several modifications that are done to the YZ TB but taper boring, a bigger butterfly with bypass hole and tps re-orientation are part of it. To test what the TB mod did I reinstalled the stock throttle tube (removed the G2 throttle tamer) and put the stock tune back in the bike. The plan was to put the TB on when I got home and ride today. The 8" of rain GA got over the weekend kept a full ride from happening but I did get a chance to ride the bike in my "2nd gear" capable back yard and can confirm that the modifications that Wade did absolutely cured the whisky throttle issue. The response is clean and the jerky nature that the bike exhibited before was totally gone. I will update this thread once I get a full ride in but I expect that I will report that I love the bike that I only liked before the mod.
