Call me a vandal - I put my valve in an electric drill using an old screwdriver holding it as a cutting tool. I kept away from the very edges then finished the job with 400 grit Wet & Dry.
That’s quite reassuring Ted. I will continue Dremelling for now then. You don’t say if the bike ran or not after you did this though; I assume it did :-)

Yes it ran and still does - I've used this method for decades on mainly on car engines in the days of leaded petrol.

With all that going on a grump is a perfectly normal reaction, so don't worry about it.
It's a lot to take in and will take time for the pain to fade.

So de-carbonising the inlet valves was easy. The exhaust valves less so. The deposits on the valve face & stem are like concrete. I am assuming this is normal (?) Are there recommended ways of removing the deposits from the exhaust valves? As the crust is so hard Im worried about damaging the valves. I have been using a Dremel clone with softish Scotchbrite mini-mops.
