The shock order form asked for weight with gear and a breakdown of the riding- sport, touring, urban. They didn't ask me to spec my own spring. I have the pre-load on the stocker generally set at 0, though I add a click when I put the camping kit on.
I thought about removing the the lowering block at the change-over, even before I realized that the tab was hitting the shock. That would violate the "change one thing at a time" rule though, and make evaluating the shock a bit problematic. I suppose I could remove the block now and ride it some at stock height. I'd need to source another side-stand though, mine got cut down-down and the Flatfoot installed.
Hadn't thought about a shock sock, that's interesting.
Modifying the tab makes sense, the downside is that I wouldn't know if it was enough until I'd bottomed the spring and had a chip on the Ohlins, or not.
