I just checked my Suzi shop manual for my '13 650. Specs are intake: 0.10 - 0.20mm (.004-.008 in) exhaust 0.20 - 0.30 mm (.008-.012 in). If your specs are the same on your '17, then you are at the lower third of the spec. As a general rule, I like to set my clearances at the midpoint of the spec - but thats just me. Were I doing my bike, and if I had to adjust the exhausts, then doing the intakes would not be much additional work, and I would do it now and rest easier. I'm sure a lot of guys would not bother, the valves are, after all, within tolerance.
