Typically head stays are used to improve handling of the motorcycle and they are not intended to hold the motor in place like motor mounts do.

Unfortunately with some of the new bikes the distance between the frame at the swing arm pivot is a little too wide and the motor does not get tightened enough at that point.

In past years the old frame would flex a little and allow the swing arm pivot bolt to tighten against the swing arm and motor.

The new frame is more rigid and even when torqued to the factory spec does not fit tight enough to hold the motor in place.

Now keep in mind we are talking about very small tolerances but at that point on the motorcycle it is critical because there is a lot of flex and stress, remember the swing arm is translating all the force of the back wheel to that pivot point. If the motor is not being squeezed tight at that location and is allowed to move eventually it will wear itself against the swing arm bushings.

This causes the motor to become even more loose then the motor starts hanging off the head stays causing much more stress than it was designed to handle.

When the motor is being held properly with all the mounting locations, there is almost no stress at the head stays which are only there to manage flex.

The way to fix this problem is to first carefully measure the distance between the frame at the point where the swing arm attaches.

Next measure the two swing arm bushings and the width of the motor at the point that the swing arm bolt goes through.

Now add those numbers up and compare it to the distance between the frame at that point.

You will probably find that there is a .030” to .050” difference. It is important to shim that out so the motor and swing arm will fit very tight against each other.

One of the big benefits of making this adjustment and fixing this problem is that the bike will handle better and will not vibrate as much as it does now.
