Shock Absorber Fitting and Adjustment:

Fitting & Adjustment Instructions for Ikon Stereodampers Type 7610 and 7614.

FITTING :

Loading diagram Adjustment diagram

A. When the coil spring of the original shock absorber – or an IKON coil spring – has to be fitted (see diagrams), the following should be taken into account:

  1. Place the bottom spring retainer in the lowest position (except for 7614 series shocks without springs, lower the seats only as far as needed to conveniently fit the spring, fully extending the shock and measuring the spring against the shock will help you determine the best spring seat position).
  2. Fully extend the shock absorber with the piston rod uppermost.
  3. To facilitate the fitting of the upper open spring retainer (e) the bump rubber (d) should be placed approx. 1 cm under the upper eye.
  4. Fit the spring (in the case of a progressively wound spring the coils that are closest together, should be placed at the bottom).
  5. Compress the spring and position the upper open spring retainer (e).

B. Align the top eye of the damper with the lower attachment.

C. Fit the shock absorber with its piston rod in upright position and with the adjustment window a directed to that side of the motor cycle that the adjusting disc (c) is most easily accessible (in most cases the outer side). – lift therefore the rubber cover (b).

D. If the attachment on the bike has a smaller diameter than that of the shock absorber, fit in that case the furnished bushing.

E. Verify, after fitting of the shock absorber, if the latter with its upper and lower attachment is fully free of any fitted luggage carriers, gear cases etc. If spacers are necessary, fit in that case the furnished spacers.

F. Tighten the nut or bolt as follows:

ADJUSTMENT :

The damping force is adjustable by means of the adjusting disc in the upper eye. As circumstances and/or load may require, you may choose from the following 4 positions (clicks numbered 1-2-3-4) :

  1. For very smooth damping under modest loading.
  2. For solo and pillion passenger use on average to good roads.
  3. For sporting solo riding or for use with pillion passenger and luggage.
  4. Heavier adjustment than strictly necessary for use with pillion passenger and luggage.

ATTENTION :

The left and right handed damper should always be adjusted to the same position, thus showing the same number on the adjusting disc. The adjustment disc must be snapped exactly into its adjustment position, and not left between positions. The MIN. position 1 and MAX. position 4 have a perceptible stop.

In addition to the above mentioned adjustment of the damping force the preload of the spring can also be changed by means of the lower spring retainer. When using the “hook” spanner / “C” spanner supplied there are 3 adjustment positions possible:

  • lower position for solo use.
  • centre position for pillion passenger use.
  • top position for heavy pillion passenger use.

For 7614 series dampers the spring pre-load is much more variable. For most applications we will have an initial spring pre-load of 20mm, less on off road bikes and more on some cruisers. The pre-load can be reduced if need be for very light riding conditions but should never be reduced to a point where there is no pre-load on the spring. From our initially installed position we recommend increasing the pre-load by 5mm to 10mm for pillion passenger use and 10 to 15mm for heavy pillion passenger use and luggage. Pre-load should never be increased such that the spring coil binds over its entire length at maximum shock absorber compression. If you want to increase the pre-load beyond 15mm we recommend you contact us before doing so.

The spring retainers of both dampers should be always adjusted to the same position.
