I had used a sharpie to mark the old HES assembly and the housing before I removed it. However, I should have probably scribed a line to mark the edge of the housing or something since half of the reference mark was on the old assembly. Duh. So now I have a nice mark on the housing, but no precise marking on the new assembly. I hoped I might be able to eyeball it but it didn't work.
So I had to do a little trial and error. I moved the ring a few mm clockwise and counterclockwise until it seemed to provide a smooth idle and reliable high rpm performance. I did not have the fancy BMW test probe or any of the other tools recommended in the manual. But fortunately I tweaked and tweaked until I hit a sweet spot pretty close to my sharpie mark. Just a few mm on either side of the sharpie mark and the bike was awful, stalling and missing. Then, wow...the sweet smooth turbine sound of the k-bike returns.
I'm going to see if there are instructions for how to build the timing test probe. It can't be all that tough and I'm guessing BMW charges an arm and a leg for one. But for now it seems to be running fine and I may decide to go out an try a longer ride tomorrow after my wife and I have out Sunday morning round of golf.
