Sterring lock left key in.turned whell broke off part of key.how do i remove lock

Right out of the book but earlier model. It should be the same.

Removal of the fork lock:

1. Loosen upper triple clamp pinch bolts, Remove upper triple clamp and handlebars.

2. Loosen fork stem bolt, Let fork stem drop down approx. 5 in.

On the left side of the steering stem there is a "half-moon" indentation that has been machined into the steering stem for the lock. Let the steering stem drop until this indentation is in full view.

3. Look on the underside of the lock on the right side of the frame and there is a lead plug driven into a hole. In this hole is a set screw that holds the lock into the frame. The book says to use a scribe to get the plug out with.

4. Unscrew the set screw.

5. Insert the key in the lock and turn partially.

6. Wiggle lock and pull until enough of the lock comes out to get a grip with pliers or other suitable tool.

7. Rotate steering stem slightly, while pulling on the lock until the lock is removed.
