Hi Allan, so I finally got a 6mm hex and pulled the start off, and zip-tied the clutch open. It looks like there is absolutely no play on the splines, assuming that I did it correctly. This is a huge relief as I have been a little worried since speaking with Shails.
Do you know anyone in the Beemer community with a shop, and who would be willing to have a second look at the splines, and even show me how to apply lube through the starter gap? If I could have a second opinion on this, that would be great.
