Are you sure? On page 57 of the owner manual it says .13 intake, and .17 exhaust:
The pages on the left side are mis-numbered in relation to the page numbers on the right side of that PDF...The left side says page 61, the right side says page 57...Makes me wonder what else is mismarked and wrong with this manual...Here is a screenshot of page 57 below.

What your information is coming from is a service manual. What I was quoting comes from the owner's manual.

Interesting. I also have the owner's manual and mine is different
than the page you show.` My manual does not show the
valve clearances; they're omitted on the spec page. The
manual I have was printed in 2004 so maybe it's
not the latest for this engine. When was your
manual printed? So I bought the right
feeler guage, found the TDC, adjusted the valve
clearances, and put oil in the engine. Next, I will
start the engine and report back.

His actually said 13/17. The 15/15 creates an overlap once the engine gets hot. The valve overlap works best at higher rpms. Which is good if you have a multi ratio drive system. The 13/17 will work better at lower rpms. Which is good when a single ratio drive system encounters hills.
So bottom line use the 13/17 for single ratio drive systems and the 15/15 for shifter builds.

Guess what?! In the part of the owner's manual that recommends
preparation for storage, I found the same spec. page 18 that
calls out 0.15mm valve clearance for both intake an exhaust. This
manual is crazy; it has two storage sections, and the specs for
the engine are only stated in the first section, not in the
second storage section. So there's two different specs
for the valves, one in the owner's manual and one in the
service manual, and who knows which is better? Think I
might have to experiment and find out which is
better.

I've ran them both. I found the 15/15 ran better with my shifter bike.

Super! Super! If this engine pops, I'll readjust the valves.
Thanks much! Mike
