Dear All,
On the way to Bromyard yesterday I put some electrical tape round the headlight bezels.
Yup, the dreaded whistling was gone.
I took the tape off for the Festival runs, and the whistling returned on the way home.
May I have a length of your neoprene Neil?
I can visit you as we are not far apart, and enjoy a hearty discussion about the joys of neoprene with you.
