Took out the WR450 yesterday, WOW! the power still amazes me every time I ride it, and thats just with the free mods.I don't know if I will even put a pipe on it, but I was wondering what that new Power Now device would do. Any reports?

I have the power now installed on my wr450. I can feel the improved off idle throttle response. Thats about all it does I think.

Has anyone tried making their own PowerNOW/JamesNOW for the WR450?
Reading the PowerNOW website the material is now steel rather than alloy I am guessing due to the rear carb boot not being a bolt on anymore.
As the rear carb boot is just rubber, is it strong enough to hold a piece of aluminium plate? The last thing we want is that to be sucked up into the engine :)

It just takes a bit of creativity to make the thing fit the 03 models... if someone does it, then send a writeup to us all... if someone wants to send me a YZ450 or WR450 to experiment on, then I will be happy to design one that fits, and do the write up... :)
