Fox fork travel change

I just got a fork that I don't really know much about, so it would be great if someone could help me out. What I do know is that it is a F-series with a Fit Remote lockout. It appears to be 80mm, and it has 9mm qr dropouts. Can I extend the travel on this fork to 100mm? The previous owner says it is a 2010. Is that correct?

Yes, it's a simple job of taking out a plastic spacer (or 2, it's been a while since I did it).
Here's a guide to the entire job.

You'll alter the geometry of your bike my effectively lifting the front end. It will slow steering response, put extra strain on the head tube, and slacken the head tube angle. Going 80->100 isn't huge but it will almost definitely void your frame warranty if you care...

If it was a 100mm fork that had the travel reduced, yes it's just a spacer, but if it's an 80mm, and you read that guide, it states that going up from 80 to 100 (or 100 to 120mm) it can't be done. Some people claim that you just remove the pin and relocate it, but they don't provide a warranty. The stancions are shorter by 20mm, as is the damper cartridge. You risk damaging either if you do the ghetto conversion.

As Alias530 said above, you put more stress on the front end when you slacken your headtube angle, and that also puts more stress on the fork.

Ooops, sorry.

I bought a new 2010 Fox 80mm Float in May 2010, pulled it apart, removed a spacer & rode it at 100mm for 2.5yrs before I sold it

Thanks lubes, I want to reduce the travel on an old (04) F-100 so I can put it on a vintage Stumpy I picked up. 100mm is too much travel for that frame. It's a 93 and I'm certain the travel back then was under 100, maybe under 80, but I'm going to go with 80mm.

Thanks for all the replies. For further clarification, I am not changing my head tube angle, as this fork is new to me, and the bike is made for a 100mm fork. Also, I called Fox and told them about my specific fork, and they said it could be extended to 100mm by removing an air spacer. However, I cannot find many diagrams on the 2010 f80 with the fit remote. If anyone has any experience with this specific fork, please let me know.
