The crux of your problem is alluded to in paragraph 3…
“3) Set up the shock within the hyperlink, then fastidiously slide the shock spacer by means of the hyperlink, then by means of the
shock backside bearing. This the place many have issues – a number of suggestions: take a look at match the spacer within the hyperlink, being
positive it slides in simple. When placing the spacer in, insert it downward and twist it again and fourth – do
not hammer! We’ve got had some points with the scale of the decrease spacer, at occasions needing to heat
the hyperlink to get the spacer by means of.!”
Not figuring out if you’re mechanically inclined and geared up, I am hesitant to explain what I might do.
When you aren’t mechanically inclined, your bike might fall over damaging the bike and/or injuring you.
Are you aware how one can safely safe your bike and jack up the rear of your bike so there is no such thing as a load on the shock?
If you are able to do that…
Are you able to take away the decrease bolt securing the reducing hyperlink to the swingarm?
Are you able to take away the higher bolt securing the highest of the shock to the body?
Are you able to take away the shock/lowering-link meeting from the bike?
If the installer needed to heat the hyperlink to achieve inserting the spacer, that warming elevated the scale of the outlet so the non-warmed spacer might be inserted. As soon as the hyperlink cooled, the outlet decreased in measurement and locked the spacer inside the outlet. One strategy to take away the spacer is to heat the hyperlink with out warming the spacer; with them joined collectively, that is exhausting to do, if not unimaginable. One other approach is to place the entire shock/lowering-link meeting within the fridge or freezer and see if the disparate shrinkage conduct of the reducing hyperlink versus spacer would possibly allow eradicating the spacer. Principally, cool the entire thing and punctiliously attempt to faucet the spacer out. When you do this, please tell us if it really works.
If that does not work, you possibly can pay a suspension specialist to see if he might press out the spacer with a hydraulic press or you possibly can have a machinist drill out the spacer. Each of these choices are prone to value greater than a used shock, however you by no means understand how a lot mileage a used shock would have. A brand new shock would seemingly run ~$400 and up relying how good a shock you need.
Nonetheless, in case your shock is the unique BMW shock that got here together with your bike; nicely, I’ve a type of with simply 4 miles on it. I eliminated it from my 2022 G310GS after I trailered the bike dwelling, so the shock has solely the seller’s 4 mile test-ride on it. I eliminated the shock as a result of I had already obtained the Rally Raid Low Adjustable Shock I ordered from the UK. The unique shock has been sitting bubble-wrapped in pristine situation in my take-offs bin each since (see pic beneath). In case you are ; I am positive we are able to work one thing out.
