I believe the fork is a '94/95 model so would be suspension corrected for 80mm? I used to run the original Manitou 3s on the long travel setting which I reckon was pretty similar to these and they certainly feel okay. The change in geometry was quite noticable with the Foxes on set at 100mm.
I have toyed with the idea of stripping this and trying to find original components but I just like the look of the M960 XTR too much so it's staying as is. To be honest I'm kind of thinking that this is what the bike would have become anyway over the years as an 'evolution' of the original as parts were upgraded etc.
The original '93 XT cranks and BB are still doing good service on my Fire Mouintain
