Mike's CB550 Project
Bryanj:
Steel wire wheel on bench grinder or in drill and yes it does feel like concrete
McCabe-Thiele (Ted):
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 vet 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.
Laverda Dave:
Same method I've always used Ted. I use an old electricians screwdriver with a slight radius filled into the edges to prevent any digging in. I go very, very gently on the carbon followed by some wire wool and oil.
