My front fork of my XT660X started leaking. I asked my local dealer/service how much it would cost to change the seals and they said around €350.
Say what?!

I could change the seals and install �hlins springs for way less than that, assuming I could do the work my self.

Have any of you done it? Is it difficult?
I see that there are a lot of "how to" videos and guides online.

How long do you think would it take for someone who is inexperienced but can follow instructions?
