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

No I don't Chris as the only way to be certain is to remove the clutch cover you can then count the teeth on both the primary gear and the clutch basket 32/73 respectively for the 2.28 to 1 and 31/62 for the 2 to 1 ratio

The output shaft is a good guide but there is nothing to stop someone having changed the primary gearing on a previous occasion

Shane, I think your bike is the same primary drive as mine as I was running 14/40 at Cadwell this year and was about 8500rpm at the end of the Park straight.
Based on the gearing at Donnington I will probably start the first few sessions for the Friday at that then as I hopefully start to carry more corner speed I may drop the rear to 39.
Ultimately your riding style, corner speed etc will determine the best gearing for you!

Thanks Mark. Well with the sprockets I've got at least I've got a couple of options to get a bit more top speed

I'm aiming to keep the same gearing on that I've used all year, maybe at Snet I'll use top.
