Fork seal - damper bolt removal?

If I still lived in that area, I could get them out in less than a minute. Holland engineering are just the other side of Buckingham to you, they can get them out.

If you still have the springs compressed, i.e. You haven't taken the top caps off there should be enough friction to allow you to undo the bolts, it needs a sharp "crack" to get them to released rather than steady pressure, so get the Allen tool in there apply gentle hand pressure to take up any slack and the turn in a fast sharp motion, or whack the tommy bar with a hammer or ratchet with the palm of you hand, it a sharp shock that you need to deliver to the Allen screw.

Don't matter how much you crack it, if some sod has used a stainless bolt, you will never get it shifted. Had a pair last year, took the heads off with the air gun and then it was time for some drilling >:(

Or if someone has drastically over tightened them, I'm doing my CBR1000F on Saturday, left seal has gone, fingers crossed that no Neanderthal has been around it in the past!.
Actually the previous owner (I'm the second owner from new)was a Neanderthal, he tried to free off the front brakes with a bar and bent a disc, tried to remove the rear brake dust seal with a screwdriver and damaged the calliper casting, the main fuse was loose in its sockets so he put a u shaped steel plate in its place , it would have blown at about 2000 amps 😄, so many bodges, luckily I got decent replacement parts cheaply but it's the last time I buy a bike sight unseen.

On my 350F no amount of tension or clamping would stop the inner damper section revolving and I ended up having to drill the Allen screw out. Fortunately I managed it without damaging the slider. It appeared to have been fitted with thread lock.
