I have a 2004 Stumpjumper FSR with a 100mm Duke fork on the front right now and I started racing last year and I really do not need the 100mm of front travel. My Duke is getting near needing to be rebuilt. I was wondering if anyone out there has ever put a 80mm SID on a 2004 - 2006 FSR and if so, how it worked out for them.

I have a feeling that putting an 80mm fork on that bike would steepen the head angle to the degree that the handling would be quicker and more endo prone than what you have known thus far. I'd stick with another 100mm fork.

I agree with GrantB. Even if you don't use all the travel, you do need the lenght to keep the same geometry of the bike..
