This is a different kind of topic.

Just wanted to thank everyone that responded to my questions about valve adjustments.  The moderators, Verslagen ("use a light, aim high"), Dave, and Serowbot have helped me significantly.  Also many others have contributed to give me insight, suggestions and confidence ...  thanks.

I've done valve adjustments on other bikes, but never on close, cramped quarters like on the S40.  With the 'tricks' and ideas that everyone suggested, plus just keeping at it until it became 'familiar' made it work.

By the way, the small, angled feeler gauges from Motion Pro worked for me.

Thanks again for all of your help.
