Title: New Fox NVA???
Post by: wwwarbird on September 20, 2010, 07:27:00 PM

 I was just over on Fox's website. Have they finally updated their C/L NVA assemblies? The .35 Stunt in their ad photos show a nice looking new setup. If so, this could be a great improvement.

  That has been out now for about a year.  Yes it IS new (for Fox), and it IS better for some (a few) applications.  It does adjust quite nicely, but cannot be reversed for inverted applications.  It is quite weighty for a NVA, and to get to the LH front motor mount bolt, the NVA must be loosened and the fuel inlet nipple rotated up out of the way.  I have several and am currently not using any of them due to the above mentioned problem areas

 Good to know Big, thanks for the info. y1 Is there a nut to hold it like normal or is it pressed in?

I use the Fox needle valve assemblies made in Italy.   VD~

  It is held in by a nut.  A 1/4th inch wrench or socket fits the nut.
