Sparrow, I'm quoting your post because you are my hero today. We finally had a nice day to do my install out in the crowded and unheated shed. I laid my tools out, watched the T-Rex install video one last time, then dug in. Three full hours later, including coming back inside to reference Sparrows spring solution, the CTX now sports a functioning center stand.
Things to know if you buy a T-Rex...starting and tightening the right hand side will cause one to question the very nature of existence. If the bike is not on a lift, there is no way to see the nut you are trying to thread on the bolt, plus due to the tight space, you can't hold the bolt in place and thread the nut, you need to hold the nut and thread the bolt into it while making sure the washer stays in place. I finally found that I could hold the nut with a needlenose vice grips and turn the bolt with a ratchet. Bad words were used.
Also, everyone is right about the spring. It does not pop right on like the video shows. After many more bad words, I took a break to go in and look at this thread again, remembering something about Sparrow's solution. Back to the shed with a length of paracord I rigged it up and in a few seconds the springs were in place. A real plus for this method is that one can do it while holding their head well back from the likely path of flying things should the cord fail. Sparrow is right...wear safety glasses.
So, I put my tools away and put her up on the stand for the first time. It took some effort as it's been a few decades since I last did it, but once I get the leverage figured out again it will be easier. I already love it.
