So, if I understand correct - if the cylinders do not reach 38 KPA OR do not balance because the screws do not have any more adjustment options - then the valve shim check/adjustment is the obvious checkpoint.
Now Valve shim check needs to get done at my local dealership, I do not possess the space or the tools to get down to checking the shims myself. I am not too convinced of their own ability to do a good job at this. I am no longer in warranty, but finding a good shop who will do this work with sincereity is hard to find around where I live.
Considering I am close to 40k, the valve shim check is also obviously due.
Could you or someone else also help answer my other questions? The replacement of the bypass screws etc?
First I have never heard of anyone
on this forum replacing the bypass screws or where you would get them, and I have been a member since 2008. I am not going to find my original post, but
my latest mod when I did my valve shim check was to extend the vacuum lines out and cap them. Basically if you had just approached your bike before
tearing it apart and happened to measure the vacuum sync and found it to be drastically out of sync, the very first thing
to do would be to do a valve shim check, out of sync is a early warning
for something going wrong inside the engine . How do I know this, well that is what I found on the 07, unfortunately I already screwed with the bypass screws. So when I did a valve shim check, I found several tight valves , when I was done I did a vacuum sync and found it was way off due to the fact I screwed with the settings
Fast forward to my 2015, I decided that at around 11,000 KM I was going to do a valve shim check, I am glad I did that because I had tight valves, this time I used my knowledge gained from my 07. I did the vacuum sync after
, the photo shown with my gauges connected is after my valve shim completed. I never touched the bypass screws
mainly because it was set correctly at the factory and the root cause of being out of sync was the tight valves.

And to go further in regards to your question about bypass screws, there have been some members replacing the throttle bodies due to TPS damage or some other part failure that is not available as a part from Kawasaki.
Last and this is only my advice, if you have room to park the bike you have room to work on it, if in your situation you have no way of providing safe shelter, I would consider asking a friend , where I live there are shops that rent space, for a day a week or a month, strictly to work on cars and bikes. As to tools, generally the cost of the tools is about 30% of the cost of a proper valve shim done by a professional garage.The fact that several members, myself and Eddie have posted step by step procedures c/w photos on this forum, if you change your own oil and can replace your chain, then you can do a valve shim. It is unfortunate that you have gone as far as you have with the throttle bodies as you are 70% there as to a valve shim.
I hope this helps, if you notice, very few replies besides myself, the vacuum sync won't cause direct engine damage, the valve shim will
if not addressed , you may already have engine damage, typically the exhaust valves.
