I know nothing about an '05 but on our rushmore bikes the mount points between for the left and right shocks are a little different in length so we mount the shorter length and turn out the other shock so it slips right on.
You need two to 3 people to set up the sag correctly and rebound is a play and see once you start at the initial suggestion.
Many of us bought from
who will gladly talk us through the process while sipping margaritas while laying in his hammock on some beach, somewhere.
Throwing in my two cents.
Twowheeladdict, you mention that on Rushmore models that individual shocks are a different length. Do we know if it comes that way from the factory when new? Do they really have a different mount point length dimension as a design? That sounds a little goofy. What if one of the shocks was changing length over time as the bumper inside moved and whole motor moved? This could be caused by the difference in the two shocks, one being a shock with rebound damping adjustment, the other just a slave spring allowing the whole motor to shift on its rubber mounts. Not to mention, the bike sits slightly to one side on it's jiffy stand with more weight on side then the other. It’s a BS system. It somewhat defies logic that our swingarm could be slightly sideways and not parallel to the ground right? Also it seems that the length difference continues to change over time/weight. Check with several people that removed the stock units and you will see a length difference between bikes. Again WTF?
I own a 2016 RGS with 18K on the clock and decided to upgrade shocks (also to Ohlins). I ride two-up 85% of the time. When I removed my shocks, they were just over 1/4" different in length (see pic). Oh my WTF? I remembered the last tire change I made, the rear tire was worn a lot more on one side then the other, like all I do is make left turns? What?
When putting on my new shocks, I too was counseled to put the right shock on first, then adjust the length of the left to fit. That is what everyone said. That too blew my mind. What if your shocks are not length adjustable? Then one side will be loaded more than the other to begin with. Sag adjustment would be different depending on what side you were measuring. How to set sag in that case? What? Didn’t get it.
Did a lot of research on the issue and found a company in Ca. that developed and sells a frame straightening device for shops and dealers (to expensive for a home type thing) and a very knowledgeable guy. What I did learn is how to somewhat fix my shock height/length difference. Attached is a pic of my new upper motor mount stabilizer link that is adjustable (like a turnbuckle) that I bought. I installed it at the same length as was my stock unit. I removed my shocks, shook the swingarm up and down a few times, then started to adjust the length of the stabilizer arm. I measured bolt hole to bolt hole length on each side with my homemade length checker (a piece of wire hanger and a zip tie, pic attached). Wouldn’t you know it, the swingarm started to straighten out. I was able to get my shock lengths back to within a 1/16” of each other or practically the same length for each side. To really do the job correctly, I should also replace the four rubber donut things that the motor is mounted to (#8 and 11 on attached pics). Nevertheless, I’m now riding more true.
BTW, my understanding is that the shock ‘difference’ is still acceptable according to HD but again WTF?
Lastly, SamJr, your shocks, like my 159’s have three inches of travel. Conventional wisdom is to set sag at 1/3 travel and for us that means 1” or 25/26MM. Not that 30mm is to much though.
Now that I have reread this tome, I will start a new thread with some of the above for general reading/comments.
