I just got a 2005 FireFly, but I am having some problems with the travel adjustment feature. Whenever I crank the travel down (so lower the travel from 150mm to 110mm), the spring on the inside is rubbing the inside of the fork making a grinding sound. I can't imagine that riding a fork that is making a grinding sound is a good thing. But I have no expereicne withe newer manitout forks so if someone could shed a little more light on the possible causes/solutions to this. I would take it apart, but I have yet to get a response from manitou if it is ok to follow the 2004 service steps or not. My guess is that they just did not properly fill the fork with oil and/or failed to sufficiently lube the srping.
