I have a 1980 HL1000. I am trying to remove the front lower damper bolts, but they are both seized solid. I've tried plusgas and a persuading device to no avail. Any tips?

They usually seize in the top arm as they dont get greased at the factory.

Do you need to change them? If theres no damage on the threads or head I'd leave them as they are.

You'll probably end up needing to drill it out

Heat can be applied to help release the rust lock.

I would just keep applying the plus gas and then get a big breaker bar on it at the weekend. So that is giving the plus gas a few days with daily applications to do it job.

If it's the bolt type  and  you can get the bolt head turning cut it off  to drift it through.

I once had a lower damper bolt shear off and I had to drill it out.
That made the hole oversized and I had to fit an M10 bolt and drill out the damper bush.
In fact I recently fitted a replacement top arm after many years.
