So, I finally pulled the trigger on a 2012 WR450F. I got the dealer down to $6k out the door which I think is pretty good. I have a 2006 WR450F now that is mildly modified. I plan on doing some basic mods to the 2012 right when i get her do avoid the dissappointment that I had on the first ride of my 2006 (before any mods). I plan on getting the competition ECU, GYTR FMF pipe and IMS 3 gal tank (only one I could find fot the 2012) immediately. The dealer is selling me these items at dealer cost. My main question is, does the competition ECU come with any maps pre-programed into it? My dealer didn't know so they called Yamaha, and the guy who answered the phone coldn't even tell me. I thought I remembered reading that it comes with a map specifically for the YZ throttle stop and GYTR FMF pipe. Is this correct? I don't really want to buy the tuner. On my 2006 I ended up removing the tiny end baffle and the whole exit hole thing that houses the baffle and drilled 4 1/2" holes through the chambers in the exhause to make it more like a straight through exhaust. I was happey with the performance improvements, but it was a bit louder than I would have liked. Can similar mods be done to the 2012 stock exhaust, and if so, how would a modded stock exhaust compare to the GYTR FMF? I have a scotts damper on my 2006, but also have a frame post that fits YZ smoker AL frames. Does anyone know if this post will fit the new WR AL frame? I am pretty sure my WR steel frame damper post won't fit. I will probably update this thread with more questions as I come up with them and I'll be sure to post some pics of my new girl when I get her home!
