How to remove the jet needle of a AT

**mmaarten** · #1 21 Dec 2006

I need to remove the jet-neelde of a Africa twin. A mecanic removed the rings that are placed under the needles to make the mixture leaner. Naturaly the bike now overheat's when ideling so I want to put those rings back where they belong... Unfortunatly the mecanic does not remember how to remove the needles.

They are fitted in the throtle-valve (ofcourse), which is made of plastic. Seen from the top there is a square hole ( 1 X 1 cm) with in the middle a round holow tube (5 mm) sticking up. The tube has threath on its inside.

It looks as if the neelde-seat (the tube is part of that) is just pressed in there, but I pulled and it did not come out.
I even screwed a bolt into the tube (it has threath) to get more grip... but if I pull any harder I might break it.

So, does anybody know the secret trick? Do I need to klick my heels together three times first of say a magic word?

I,m sort of desperate since I,m in a hurry.

I own an older different AT so let's quote the Haynes manual: ".. Thread a 4mm screw into the top of the needle holder (one of the top cover retaining screws is ideal), then grasp the screw head using a pair of pliers and carefully draw the holder out of the piston. Note the spring in the base of the needle holder. .."

Looks like you did it already the right way. Good luck!
