PowerNow free mod?

I caught wind of something called a "JamesNow" in the WR forum and wondered if 1) This can be done to a 99YZ400 and 2) has anyone tried?

I gather it involves cutting a small notch in the intake side and sliding a machined metal plate in the new grooves to mimick the PowerNow plate...sounds kinda sketchy... but if it works like they say a PowerNow does.....Hmmm...

couldn'y really find anything in a forum search.
