I've found that sometimes the 1BA screws are to tight, so must be 3/16. But a 1BA tap through the thread opens it nicely. Ron

Cheers Ron, I’ve bought some stainless 1ba screws with the correct head profile and a set of taps. So just got to get the old screws out cleanly now.

In case anyone is looking for Amal screws, I have just bought a set of stainless steel 1 BA screws, with the correct head profile, from RGM Norton Ltd (www.RGMNorton.co.uk). A reasonable price and look great on my newly plated levers and throttle twist grip.
