As per my other thread about what chain is on my bike, sprocket has arrived and I had 30 minutes spare so thought I'd crack on with this little task.
Removed the sprocket cover to see a different setup to my 996 (plate with 2 5mm bolts holding sprocket in place) on the 999, and I'm guessing any Testastretta engine it's just one big (32mm) nut holding the sprocket in place.
Tried as hard as I could to get the thing to budge, but no joy, then it dawned on me maybe it's a reverse thread? does anyone know? anyone got any ideas how I can shift this nut etc
