I think its for smaller Kawasakis too, still might have been broken though. In any case i got the new one very cheap and now its the right thing so no biggie. I had charging issues and still not sure if the stator is good as well.
But all in all the bike definitely doesnt show any of previous issues, i let the engine get really hot and still no problem, drove for at least half an hour after it was hot. Passed a hill where it always stalls with 6-7k rpm all the way, no stutter at all.
Could the much colder weather make such a difference?
I believe that tempurature could be at play here.
It is possible that the plastic cap on top of the throttle slide diaphragm is Warped!
Any warpage could allow vacuum to leak during fully warm running and the throttle slide to not fully rise,
when you request it.
I'll suggest that you remove, inspect and clean the sealing rib on the diaphragm slide and the groove that it fits in and CHECK the plastic cap for level fitment.
Modify at "YOUR OWN RISK"!
