It's been about a month since I replaced the faulty SAS after having installed the Steering Update Kit. My Ryker has been performing as it should, with stability control kicking in only on very tight aggressive turns. No more left turn bias, and no hint of it on the left turn to my house that always caused problems. Looks like my problem has indeed been fixed.
Great Job on the fix, and thanks for sharing your experience, DickB! I am having the same issue, no codes and wobble during left turn. I am from Northern CA and do lots of mountain twisties. I bought 2019 Ryker with 900 miles on it and have a love hate relationship with it. I replaced the rear drive shaft at 1500 miles, I have the dreaded fuel pump whine noise at 3000 miles and now the left wobble at 5400 miles. I do ride it hard but it's ridiculous having to deal with so many issues with very little miles on it. I am very handy with tools so I plan to repair myself. I ordered the noise dampening kit and the steering kit and plan to buy the buds2. I was hoping you would share the web link of where you purchased it from. Also, is your Ryker still running strong with no nanny issue. Thanks again.
