EDITED by request:
so, the original reported failure was here in USA, on a 2013, with no height modifications.
then, the second report is your 2008, with links to raise the bike. Located in Venezuela.
then, a friend of yours, again in Venezuela, with a 2015, and no height mods, has had the same failure, relayed to us.
(which seems very strange, to have 2 failures, on bikes from people that actually know each other).
What was the outcome/and follow up, with regards to your friend's bike getting repaired, as I would assume Kawasaki was contacted by him, being such a new bike?
the original reported bike was completely repaired by Kawasaki.
I suggest you, and your friend, contact Kawasaki, and fully report your issues..
and have them discuss it with you. Without owners reporting issues like this directly to them, there is little Kawasaki can or will do with regards to any of this. We cannot do it for you.
I apologize for appearing rude with regard to your report.
best of luck.
