Anyone using a "Power Now" ?

Ive read in some mags that the power now part can give a 2 1/2 HP increase at mid RPM. Any truth to this? Any re-jetting or anything else to be adjusted?? Thanks ! :banghead:

I would have a hard time believing a 2 1/2 HP gain, I did the homemade version on my '99 400 along with the accelerator pump mod. The major difference I saw was that it dramatically cleaned up the low end bog.

I did the JamesNow mod as well and noticed better off-idle response.

I have a Power Now on my 01 WR. The only thing it seems to have done for me is maybe help it start a bit easier. Didn't affect jetting at all. I didn't really notice a big improvement anywhere else.

I have one my my 03 WR450 and I didn't really notice a huge performance gain either. Your $100 is better spend elsewhere, IMO.

When we're done here you'll all be wearing gold plated diapers.

OK.... I feel stupid now :banghead: but what is the JamesNow mod? Is it the same as the one listed here??

Here is the PDF explaining how to do it.

I dont think that it would affect the bigger bore bikes much, only the 250f's

Damn!! I Just LOVE that COWBELL!!

You can really feel the difference with the power now at just off idle with more grunt and better throttle response. I do not recommend it for mid range performance gains. Just dont buy the Power Now Plus version for the back side. I got both and ended up just using the standard Power Now. The plus model just screws up all the jetting on the idle and needle circuits. :banghead:
