I've been on the forums all night to try and find out. Some think you can't get to 65mm because of a groove inside the pulley. If so, I may just go for 68mm and think about stacking a 178mm later.

If you don't mind me asking how much is your guy charging to do the machining? The owner gave me a 'couple of hundred' as a verbal today while I was with him. (left it with him for a 'day or so' for him to work out). He thinks he can fix up the loose rivets on the backing plate too! Hope so. That means I'll mod the original and keep the one you sold me as the fall-back / spare.

Cheers,
James
