Installation Instructions
Fits: 2013-up Gas/Gas EC250/300 and all 2014-up dirt models. (Both 2 & 4 strokes)
KoubaLink PN GG13-2 link lowers the rear 1.5".  Replaces Gas/Gas link assembly PN: 5035851153

**Will not fit  the 2013 Gas/Gas XC250 /300 or any bike that does not have the one piece link.  The KoubaLink GG13-2 replaces the stock link that has the casting number on the cross piece of "BF30-001CT-4512".


KoubaLink GG13-2 link shown above.

1) Raise the motorcycle with a bike stand, milk crate, etc., so the rear wheel is just slightly off the ground.  Loosen and remove the two 17 mm nuts from the link mounting bolts that hold the stock H link to the rocker and engine cradle.  (Nut is on the right end of the front mounting bolt and left end of the rear mounting bolt).  Then push the rear mounting bolt out the right side.  You may need to lift up on the rear wheel slightly to allow the bolt to slide out freely.  Now push the front mounting bolt out the left side.  You may need to raise the rear wheel a little after the bolt is removed to allow the link to fall out the bottom. 

2) The new link comes with only the bearings and seals, so put some grease on the needle bearings in the KoubaLink and install the center sleeve and both end washers from your OEM link into the new KoubaLink.  Install the new link on the bike (bearing end forward) with the grease fitting facing down and towards the rear by pushing the front mounting bolt in from the left side, be sure the flat on the bolt head is aligned with the tab on the clevis.  Next install the fork end mounting bolt from the right side.  You will have to raise the swingarm to install the fork end mounting bolt as the KoubaLink is a little longer than the OEM link. *Left link engraving will be upside down and backwards, right side will be readable left to right.  You need to pump some grease in now as sometimes tightening the mounting bolt nuts can seal the bearings too tight to allow the air to escape.  Torque the mounting bolt nuts to the Gas/Gas recommended 100Nm = approx 75 ft/lbs. 

3) If the link is used for lowering purposes only we recommend the rear race sag be set at the Gas/Gas recommended 105 mm's = (approx. 4.125") and you will get the amount of laden rear lowering claimed for that link.  You can run less rear sag for a better ride but that does take away from the laden lowering amounts.  If you need to reset the rear race sag the easiest way we have found to adjust the rear spring preload is to use a long punch to loosen the top jam nut and turn the spring and the preload nut at the same time.  **You may have to put some lube on the shock threads to allow the nut to turn freely. Turning the spring/nut "clockwise" increases the preload and decreases the sag.  **Do not forget to tighten the spring jam nut after setting the sag. 

4) You can slide the fork tubes up from the stock position by loosening the pinch bolts on the triple clamps.  How much you need to slide them up will depend on the amount of rear race sag and how quickly you want it to turn.  Just keep in mind that lowering the rear more than the front slows the steering but makes it more stable on the striates and visa versa.  However much you change the fork tubes, be sure they are both set at the same position and that the triple clamp pinch bolts are torqued. *Do not over torque the triple clamp bolts.  (Gas/Gas recommends 11Nm = 96 in/lbs for the lower clamps and 15Nm = 132 in/lbs for the uppers.)  Sliding the fork tubes up farther than the stock handle bars and mounts allow could let tire hit the fender if the forks are bottomed.  :-(

*Disclaimer:  Raising or lowering the rear more than the front can change the geometry and could affect the handling, so be careful out there.
