    Fork oil refresh, ESA fork Longer.

    Hi I've read the earlier thread on a differing fork length after fork oil refresh, I've had exactly the same issue, the ESA fork ended up around 6mm longer, however on reassembly it all pulled true again with the wheel Spindle, I've asked this question on a few FB groups, other owners seemed to think they had the same issue, it was also mentioned that this is due to the ESA fork not being connected/energised and the nitrogen cartridge just relaxing, I have ridde6the bike since, seems more spirited as I serviced the rear linkage at the same time, but the rear shock seems way off, perhaps a recalibration is in order, all that said any suggestions or ideas are welcome, cheers.

    Not sure what the outcome of that thread was but it is true that the ESA fork is locked unless ignition is on, re- the shock, there shouldn't need to be any recalibration, did you check the linkage went in the right way around? In my rush I put it in reversed once and sure the bike was much softer and nicer ride but also risk bottoming out the thing haha, the linkage should be parallel to the ground with the long end connected to the shock, short end to swingarm did you remove the damping cartridges? If not there shouldn't be any issues.

    Yeah I'm 99.9% sure the linkage is right, but I'll check tomorrow now lol, think with me moving the swing arm up and down while removing and refitting I could of possibly moved or damaged the ride height/level sensor, bike feels great on A roads, but anything slightly bumpy having me out of the seat.

    Don't worry the ride height sensor is sturdy, it wont go out of whack like that, or it'd throw an error, if you're worried you can check with motoscan or GS911 but I think it might be just that  now your linkage actually works lol, have you checked your preload settings?

    Hold down your suspension button until the helmet starts flashing in the top left of the LCD, Options are: rider, rider + luggage and 2 up (+lugage)

    Oh I can do that, got it on 1 helmet as per usual, I thought there were settings in the main dash, setup menu.

    This is why i always thrawl through the manual before getting a new bike, sometimes there is really cool (not so) hidden features   :008:

    Not sure then, the XR is a stiff beast, but might be better to draw a conclusion after you've made certain everything is back together correctly, including the forks, on that make sure they're in the correct amount, the forks stick through different amounts on low and high bikes. Only last thing I can think of that might make the rear buck you off is tyre pressures.

    I'll work through it, tyre pressures are fine, my front tyre is ready for replacement, I've also ordered a new front wheel bearing, it wasn't bad, but just didn't feel right one side, an easy job to do and not overly expensive.

    The recalibration function doesn't work with our K49's, I emailed them a few months ago.
