    KONI rear shock settings help needed

    Hi,

    I installed some KONI rear shocks that I had lying around, but after a test ride found out that the setting is way to hard...
    Above 50 mph my neck and back had to take all the bumps in the road.

    I noticed that the shocks are adjustable with a tool (that I don't have)...

    1) What is the softest setting ? the setting where the spring is compressed at maximum ?

    2) how is the shock normally adjusted ? just by turning it with the appropriate tool when the shock is mounted ? or do I need to dismantle it from the bike ?

    3) anyone has a tip/trick of doing this anyway without the 'official' tool ?

    thanks in advance,

    gert

      You can adjust them on the bike. Just play with the settings until you find what works for you.

          can this 'playing around' be done with another tool (than the original one) ?

              More than likely. I've used a pair of grips in the past, and a short tommy bar. Depends what you can get on there.

              The risk you take is slipping and scarring the shock. I don't care about that

              On preload, the shock is on its softest setting when the spring is least compressed, ie: on the lowest step.

                  least compressed, so that is, when looking at the shock,
                  the highest step and not the lowest ?

                  I think I'm getting confused here...

                      The softest setting uses the least amount of spring preload. Also check the damping adjustment knob; the lower numbers are softer than the higher numbers.

                          Try a strap wrench so you don't bugger up the shock.

                              When the spring is longest it is softest.

                              Work it out from there, mate
