My Perry's, the 900 series, have a slot for a screwdriver that sticks
out about an eight of an inch. I have a short piece of thick wall tubing
with two set screws in it. I put a piece of wire in one end, and attach
this to the rounded area around the screw slot. I got this piece of
tubing from a hobby shop about 1990, and I have no idea who made it. But
you can probably do it yourself with the pieces in the K&N bin at your
LHS. Form your description I'm not sure we have the same style of needle
valve, however.

Alternatively, on my Patriot, I put a hole in the side of the body and
epoxied in a piece of outer pushrod tubing lined up with the needle. It
guides the screwdriver into the slot.

On 2/25/2004 9:26 PM Ted shuffled out of his cave and grunted these
great (and sometimes not so great) words of knowledge:

I did one extension (not an ST3000 though) as follows:  Took a piece of
brass tubing that just fit over the outside of the needle valve and JB
Welded it in place.  Then I bent my 1/16" wire and put a small 90 degree
bend in the end that would go into the brass tube to keep it from
turning inside the tube.  Squished the brass tube with the wire and JB
Weld inside it.  Works great - just make sure the needle valve is CLEAN
before you JB Weld the brass tube to it.

If your Perry is the same as that shown on Tower's page....

... then the steel needle is pressed into a brass housing.

I was wondering about this same thing since I'm putting a Perry on a
OS 60 Goldhead to get rid of the airbleed carb.

Here's my idea......
Get some brass tubing that is a snug fit to the boss on the Perry nv
housing.  Cut it ~1/8" longer than the boss length.  Scrounge up a
1/16"  PLATED BRASS wheel collar.  I do not recall if nickle is
solderable.  If it is not, file off the plating on one side of the
collar.  Solder the brass tube over the nv boss and to the side of the
wheel collar.  You now have a 1/16" hole with a set screw on the
side.....   VIOLA'.
