I’ve thought about changing the bushes myself. I haven’t because I’m a s**t house but got some advice.
To remove the bushes I was told to use a washer that has been filed down so that it fits through the bush and then you should be able to flip it so it catches the outer edge of the bush, then use some threaded bar to pull the bush out. Before you have a go remember to measure how deep they are in the fork leg.
I also got told that they have to be sized for each fork, not too sure about this?
To fit bush I imagine that you just tap them home.
If you do manage to fit new ones can you post up a pictorial.
