Shane depending on the actual primary drive ratio the bike would have had as standard road gearing
15/36 gearing if its a 2.28 to 1 primary (a lot taller than your 14/40 which is equal to 15/43)
and
15/41 gearing if its a 2.00 to 1 primary (not far off your 14/40 which is equal to 15/43)

right
the very first 600SS came with a 2.28 to 1 primary drive and had a 15T front sprocket and a 36T rear sprocket

During 1994 they changed the primary drive to a 2 to 1 ratio a change of 14%
as such the final drive gearing need changing to compensate so the rear sprocket was also altered by 14%

Knowing which one you have is the key

Ok Kev thanks
Is there any way of telling which primary drive ratio I have?

well you could remove the clutch cover and count the teeth on the primary drive
the other way of telling is the output shaft for the front sprocket is shorter on the 2.28 to 1 engines, maybe Mark Hamilton or Andy Claridge could let you know what their early engines measure

I think Kev means remove the Sprocket cover, not the Clutch cover
