I am going to say this for the last time.
There is NOTHING to be gained by removing the rear engine mounting bolts.
There is absolutely no adjustment or anything else available or to be gained by doing so.
As it says in the manual, you are to replace the rear two bolts first. Once you do THAT, there
is no play, or flex, or adjustment, or movement of ANY kind at the front of the engine.
NONE, RIEN, NIENTE, NEIN. Period, end of discussion.
I have studied the bike and the manual for a long time, and there is no provision for adjustment, nor should there be.
I have been working on all things mechanical for over forty years.
This bike came like this from the factory, where they had some trick in assembling it that they are unlikely to share with me.
On other machines I have seen factory parts that were manufactured in a range to overcome this type of problem, but that has gone away with newer casting and machining techniques commonly used now.
Kawasaki messed this bike up when they built it, and I will fix it. I am not unhappy except for the time I wasted thinking I had done something wrong.
I started riding bikes in the 60's. I am so happy that I have these beautiful machines to ride now.
Please note that nowhere in this thread did I mention complaining to Kawasaki. I will continue to buy their products as I have since 1971.
And that is all I have to say about that.
