    Anyone experimented with fork height?
    Had my bike for 2 years now and I’ve always felt it wouldn’t turn as well as it should but put it down to coming off lighter 350LC 2 strokes.
    It never seemed to want to turn on slower tighter bends and has caused me to run wide regularly and have to brake. Seemed to be ok in faster bends though.
    Was in a few bike dealers looking last Saturday and saw 4 Speeds and notice all their forks were through the top yoke more than mine, on both Ohlins and standard suspention.
    B4 I collected the bike in 2018, it had forks removed to have new seals, and turns out they were not put back to their correct position.
    My forks are the right hand pic and left is where they should be, the line 5mm below top yoke.
    Measured mine and it is at 13mm, after a little research 4mm of ride height equals a change of 1mm in trail, higher ride height = longer trail and slower steering and lower ride height = shorter trail and faster steering.
    The situation was probably made even worse last year when I had the shock serviced and set up with the correct sag which lowered the rear a little making trail even longer.
    Hope to get out today if rain stops to see if it’s made a difference.

    Can't hurt to try, it's easily reversed if you don't like how it feels. Have a good look at how the tyres are wearing as this can have a dramatic effect on how the bike steers, particularly the right shoulder on the front. Even if you aren't a roundabout hero that side can wear more than the left. Also you can experiment a bit with tyre pressure. I run mine a bit softer, maybe 34 front, 40 rear.

    Got fairly new S22s on it and wear is fine, all level either side of the sipes.
    I tried lower pressures that was recommended on here, 33/36 I think and didn’t like it but going to try 36 rear once I’ve tried it with the new fork position today, but don’t want to change 2 things different from how it was last Saturday.
    May also try slightly less rear sag, as it was set at 38mm last year.

    Looks like about where I dropped mine to, 5mm to the line down from 10mm.
