Please offer an opinion if this is a worthwhile Mod for a 05 WR450.

It is only noticeable and helpful when rock crawling with throttle control and no clutch work. Forget the plus version it leans out the JD needles too much when uncorked. I would not buy the Power now for high reving wide open riding. It is real nice on tight enduro single track trails if you are not racing. Racers wont find it useflul. Trail riders on nasty trails will. :cry:

After doing all of the free mods and going one up on the pilot jet, I rode my bike again after installing the Power Now and going up one size on the main jet. I believe the Power Now made a big improvement when getting on the gas, especially in 2nd and 3rd gear, and continues to pull in 4th. Below is a copy of what I wrote in another thread and covers just about everything I've done to my '05.

Just my 2 cents, but instead of the JD kit, I installed the Power Now, did all the free mods, one size bigger on starter, pilot, and main jets, and 1 and 3/4 turns out on a Storm fuel screw. The bike rocks! Can even keep up with my friends KTM 525 going through all the gears as well as top end. Still has a little hesitation some times on starting with the e button so I might go up one more size on the starter jet.

I got mine for a YZ250F at motosport outlet. It was a surprisingly good difference on the bottom to mid of the bike. First time on the track was at an indoor, with it i could tell it was easier to do the jumps from the inside lines.

When I fitted a PowerNow (about 2 years ago), I was riding in pretty deep loamy conditions. With the PN, I found I could pull third gear hard through certain corners, that prior to the PN, the 426 would bog in third on the same corners. I just noticed it sharpened up low-mid' range response, which is always good..... :cry:
