I had my 24t sprocket repaired by John Heming.
I'm pretty sure he could resize your 21t to 24t.
Ph for john is 01547 530759.
The bike goes a lot better now..John

Hi, my model 9 has a 21t engine sprocket and is consequently a little low geared. . . even after fitting a 18t final drive sprocket. Can anyone suggest where I might find a 24t one?
