I noticed a strange ticking sound coming from the engine, reading other posts I deduced that it could be the cam chain tensioner. Is it possible to adjust the original tensioner without opening the engine?

The ticking could be normal valve noise. Does your motorcycle have the automatic tensioner w the cross-wedge? If so, you could remove & re-install the cross-wedge to reset the pushrod. see diagrams at Kawasaki.com or Partzilla. Also, if it hasn't been done as part of normal maintenance, you should do a valve clearance check. doing the check is fairly straight forward. changing shims is more work, but doable.

Yes, that appears to be the cross-wedge type found on many 80s models.
Remove the cap then pull out the wedge & spring. clean & lubricate, then reinstall.
I use Permatex Ultra disk brake caliper grease in the little packets.

Do not ignore the valve clearance check, especially if the motorcycle has very many miles. but regardless of the miles, it should be done so that you know for sure.

It is obvious to me that you do not own a Kawasaki Service Manual. You should buy one if you plan to keep the bike or do any work on the bike yourself. Owning a KZ without the manual means you will not perform any of the maintenance that is required. Not good! Until you buy a manual you need to use the one posted right here on KZRIDER (see below).

There's a better 750-4 chain drive manual floating around the internet. Yellow/Gold cover w color wiring diagrams. It may be linked here in the Filebase on KZR. If not, search KZR for 750Turbo manual.

I don't understand or maybe I'm missing something. The manual at the link I gave covers the KZ750-E1; E2; and E3 models and several others. The original poster's title says he's working on a KZ750E. Wouldn't the manual I gave a link to cover his model, or does he have a later model not in the manual I linked to? Thanks, Ed

Martin means this manual:

kzrider.com/modules/ServiceManuals/GPz750.pdf

It says GPz but it's the same manual (KZ750 Four), just better quality.

Leaking exhaust gaskets can also produce a ticking sound that can make one believe it's the valves.
So when you have checked your valves, replace the exhaust gaskets and make sure they seal.

For sure I have found one problem, I'm going to replace this part of the tensioner due to the condition.
Maybe it can be the mainly cause of noise due to the fact it can't push well the chain.
