    I just mounted a pair of Ikons and am quite impressed.

    It’s been a while but I’ve now been for a decent ride with the turcite bushes and Lansdowne dampers. What a difference, all is now silky smooth in the suspension department and a significant improvement over the standard forks.

    If you have stiction in your forks, it is usually cured by tying the lower for yoke down to the wheel with rope with everything slack and the forks compressed - then tightening the bolts and top caps on the yokes as well as tightening the axle nuts, while everything is still tied down. Then remove the rope and test the bike. Fork braces in particular can be culprits. Some have slotted holes in the joining piece. If you are doing the tie-down tighten the bolts in the fork brace last. I would not buy a fork brace which was not adjustable for width.
    When you have the front end tied down, it sometimes helps if you flex the forks by twisting them a bit each way. On old bikes the clamping surfaces of the yokes can corrode making self-alignment difficult.

    That’s sort of what I did, I fitted the forks and front wheel with the forks fully compressed, tightened everything up from the top down, tested them for free movement, removed the wheel then fitted the dampers. With the standard bushes things still weren’t stiction free which is when I decided to fit the turcite bushes.

    I had fitted new stanchions and bushes and they were just too tight a fit, even with each fork off the bike the movement was stiff. As the standard bushes are oilite reaming them can cause issues with the holes in the material so isn’t a great idea.

    Anyway all is now super smooth so I’m happy with the end result.
