This is a long shot but I have a number of 39mm diameter titanium valves made by Zanzi of Italy for a 996RS. 106mm overall length, 7mm (nominal) stem diameter and the collet groove starts 3mm down from the top of the stem. Andy
Just re-read my advert and realised my pricing strategy is all to cock. Who on earth would want a single valve ? Dick :Bag: ! So, £180 for a pair (2) of valves or £320 for a set of 4. If you want more than 4 (and I have more than 4) I'm sure you can try and squeeze a little better discount out of me if you ask nicely . Andy
