…and that is why I have cleaned up the new valves. I’m not sure if it will really make any difference, but in theory its got to be better. Not least because A. Graham Bell reckons it’s the thing to do (according to “Performance Tuning in Theory and Practice”)
So I dropped in on Alain Antoinette, who runs Spacesavers Plus in East Finchley. Specialising in light engineering, engraving, signmaking and CNC laser cutting in various media he’s been a great source of advice. He let me use his lathe and tools to remove the sharp edges from the valves, clean up the surface, and give them a little polish. What a guy, thanks Alain!

On the left is the untouched valve, on the right one of the inlets after our attention.
And here is a close up. You can see both the smoother profile and the polish on the surface. I used Scotchbrite, then fine Wet n Dry (first dry, then polished wet)
The polish had touched the seating area of the valves, so I very lightly lapped the valves in again, just to be sure! Boring? Pedantic?? ME???!
