F2 Powerback kit

[mbx5]

Anyone see the article in Dirtwheels about the F2 Powerback kit - timing change, some jetting, etc?

Anyone try this kit? Is it worth the price? I have read that all you need is some jetting and dont really need their kit?

I have an 07 YFZ....a friend of mine has an 06 Raptor 700 SE and just bought some EFI programming module and is talking trash about how he has the upper hand now so I am looking for some cheap horsepower w/o changing the pipe...

i have it and it works. there are also magnetic oil plugs included in it so thats good. you get a 162m 48p screw new needle and instructions for the exhaust and cam mod.
