Hi everyone. I bought a brand new 2012 WR450 this yesterday. I love it. It rides great! Did a few heat cycles on some logging roads this weekend. I have a few questions. I opted to have the dealer not install the GYTR comp ecu because of the price they wanted to install it. I got the screw out already and have read on here I can plug it with a screw thats 1/4 inch long. Does the comp ecu make a difference in power output by it self? I know it allows the use of the tuner which I will get later on when I get a pipe. If the comp ecu doesn't make a difference then I will just buy a shorter screw for the time being. What do you all recommend? I also pulled the axles out only to find them dry. Zero grease. Pretty interesting they don't grease these things from the factory. Thanks for all the help.
