I may possibly have a 42 tooth, will have a look tomorrow, but surely exact size will vary according to what chain size it's made for?

i have a 530 chain on a Quaife ATB QDF14K chain lsd but i only have a 46 and 47 tooth which are way to far off

Just checked, sorry looks like the 42 tooth I had got binned, only thing I have is a 37 tooth which is 200mm across the diameter, point to point of the teeth. That was for a ZX10 chain which I seem to remember is also 530.

I normally use 46 tooth.

Just one additional thing to be careful of, never use a sprocket which has an exact multiple of the front sprocket size, eg 14 to 42, (3 : 1 gearing) it will give horrible resonance & rumble as you always get the same teeth coinciding with the same teeth on each sprocket
