stock shock with 500/560 spring

    After waiting a while, my doorstep was blessed with more unexpected goodies yesterday. I ordered a Stock rear shock, with a progressive 500/560 spring. Mike at Dual Star installed the spring for me and I am very pleased with the results. The reason it took so long is that there was a concern over the ID of the new spring not matching well to the spacers on the stock shock. The result is that the new shock spring hangs off the spacers and is in less contact than the original design intent. Mike was waiting on Progressive to give word about the need for new spacers. Apparently it was deemed fine, and so I have a new shock. I think I have a fix for the problem but I'm not willing to tear apart what Mike has done to try it out just yet. The fix is to make another spacer to fit over the cast spacer, pretty much like an adapter. This will change your pre-load a bit, but some experimentation will find out just how much. The length change between setting #1 and setting #2 might be all that is effectively eaten up by the new adapters. I took some photos last night to illustrate the concern. Sorry for the large file size, but for clarity I had to make it somewhat big. I've sent two files, one of the pretty new shock, and one showing the close-ups of the old dirty shock. Too lazy to clean it until I'm ready to tear into it to find out how it works. Mr. Carl has inspired me to tear into my old shock to find out how to make it better. It'll take me a while as my plate is already over-flowing, but if someone has any insight, I'd love to hear it and talk with you. LaterZ Dash
