Still hard to start with the air filter removed?
Did you confirm spark during cranking without pushing? (timing light)
Did you actually run compression test? (the gauge that screws into the spark plug hole)
Did you set carb float level and idle passage adjustment as per service manual?

Any four stroke motor only needs three things.
A spark. At just the right time.
Compression. A piston and two to five valves doing their job.
Proper air to fuel ratio. Carb delivering 14.5 to 1.

Something in that pyramid is messing things up.
Water in exhaust.
Wet air filter.
Weak to no spark when cranking but adequate for pushing.
Mixture off.
Engine let go, to little compression to start easy.

And blowing a fuse just because of heavy rain is NOT right. Something else is going on.
Clean water conducts enough to mess up sensitive electronics but not take out a 10 amp
fuse without there being something else major fuxed up.

I've had my gz through torrential downpours and 18 inches of flood waters. It has never
blown a fuse or died on me cuz of it.

Could be that the starter itself needs some TLC. If it is dirty and corroded inside it may need to be disassembled and cleaned up a bunch. The GZ has a smaller battery that can not overcome the dirty condition and still provide enough power to fire the ignition. Using a larger battery to boost the bike is a good way to fry a dragging starter.
Seen this in the past with cages. Dragging starter and a no start condition. Dead of winter and no place to plug in the block heater. The cage was power boosted with 24 volts finally and the starter went up in smoke. Me: outside at 40 below changing starter. New starter and battery charged up. Engine started first try.

This is a good idea. Water Warrior
I had an old kawi that would eat windings on the armature.
Made it nearly impossible to start except by pushing.
I picked up a used starter that worked a bit better then went to a rebuilder and
got enamel winding wire of one gauge heaver and rewound the original.
It was Way not easy to do. And you have to do it exactly right.

Ended up with a great starter motor... But I digress...

Perhaps starter is weak. Perhaps battery is weak.
If you try a jump from a 12 volt car battery keep the cranking to a min or you
will find that starters limits real fast and do serious damage.

Frankly. These bikes are very easy to start when in good tune and you have learned their idiosyncrasies.
By the way.
If it's real hot out...
Don't even touch the choke. Just turn throttle slightly and crank.

With the starter button pressed, and the starter motor running, have you checked the voltage between the starter +ve terminal and ground? and, what is the no load voltage between starter motor and ground, with the terminal unfastened from the starter motor, and the starter button pressed?

When I said that I was no mechanic, that's for the engine, but I was an electrician for fifty years, before I retired, so I tend to know more about the electrical side than the mechanical.

Ok. I was born into a fruit plantation owner famely that also made plantation eqipment, but never lerned the trade due to my age. The ptoduction was cansled and plantation sold. So love machines but knows little of what makes them tik and how they are wired. But I try to learn as I run into problems along the way. Learned alot from the Jinlun JL150 ;-) but unfortunently not enough

Ok, so.... Now we have trying to meshuere at all the points of conections at the bike and we did not get something "off" So I think that the cdi box must have gotten a "spike" when that fuse blew.??? Dose it sound plausable? Otherwise I am lost.
