NGPZ - More t'shootin' ...bike dies after highway run

[John Soliday]

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

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
quits.

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.
