Any recommendations on avNow vs. PowerNow vs. JamesNow??
Posted February 21, 2004 - 02:18 PM
In researching this, I found the following EXCELLENT links:
From Motoxer62's and AV's R&D, it appears that the avNow is the way to go. But I'm still not clear on how to go about this for my WR426...Can anyone help?? Is there a TT member doing these? I just want to make sure its done right, and as my wife says, "pay someone else to do it then". Thanks honey.

I guess this won't be a secret link anymore unless I change it again...
I would just recommend getting the power now, that would be the easiest and quickest way to stay in the game. I've read all the post you mentioned. I thought about the james now but finally decided the effort to build wasn't worth the time since power now was available with similiar results.
basicblues - I ran with the PowerNow for one season, made the avNow which works a lot better than the PowerNow, sold my PowerNow and never looked back. If you think they create the same in output (that you can actually feel), you're just missing out. For older models, the venturi are removable so it's easy to make the avNow. In your case, the 450s' carb don't have that removable venturi piece anymore, so you would have to cut the slits into the back of the carb and THAT scares a lot of people away and they just buy the PowerNow - who can blame them? The older models' venturi pieces can be bought if you mess up and they're relatively cheap - truthfully, the slits that you have to cut into the newer carbs are only 3mm deep, so it's really no big deal, but people like to get things done the easy way (i.e. already made, plug and go). I know the differences between the avNow and the PowerNow, you can NOT feel that much of a difference in torque/snappiness(sp?) in the PoweNow, but the avNow will give you a big surprise and grin with how much harder it pulls. I still smile when I think back to the first test with the avNow - all I could say was wow, wow, wow and kept smiling.
Anyway, I don't get any $$$ for this advice/research unless I make the avNow for people (which I don't ask for this work - people ask/beg me to make it for them and pay me for the labor and parts - it's really not worth my time to do all that work).
Do as you wish, have fun guys.

What gauge copper/sheet metal did you use? And I've also heard some horror stories about the epoxy chipping away and making whoopee with the piston, I know AV recommended some, does it hold up over time (and wipeouts)??
I used a license plate. Perfect item, 1mm think and aluminum. Best of all, it was free.
