I'd look at the gas tank vent.  Try riding it with the gas tank cap open and
see if it goes away.

Subject: NGPZ - More t'shootin' dies after highway run

Well, another odd thing going on.  My wife's Ninja 250 quits when she comes
off a freeway (after typical 70-80 mph run for at least several minutes).
When she exits and comes to a light or whatever, clutches in and poof, bike

It started happening just a couple days ago and usually started right up,
but today she messaged me and said it took a bit longer to restart, only she
was in a toll lane for the (San Francisco) Bay Bridge - a horrible place to
stall out.

Any suggestions for what could cause this?

I don't think it's over-cooling; it's liquid cooled and I think it runs warm
enough that the t'stat is wide open after it warms up
anyway, but I could be wrong.   I'm thinking it's some other issue.

Things I know that are potential existing problems:

Battery is on it's last legs; it starts and charges OK I believe, but the
battery capacity is getting pretty low.  I have a new battery waiting at the
shop now.

Head-cover leaking - there's a bit of oil in the spark-plug holes and around
the cylinder head cover - I have gaskets on the way for the next
valve-adjustment opportunity, but could oil in the wells cause something
like this?  (I'm thinking "probably not".)

By the way, regarding the slow-to-idle issue - I didn't work on range bikes
this week, so i wasn't able to try the vacuum check tricks.
Next week probably.
