I have read trought the document:
KZ 650/KZ750 four starter clutch repair. - KZRider, KZ, Z1 & Z Motorcycle Enthusiast's Forum
I could not catch he was talking about a spesical tool for bearing pulling?
He is mentino that it can be handy to have spesical tool for the main gear clutch (I had one when I replaced the friction plates, but have sold it..)
If I understand correctly, I need to take the bearing out on the right side before I’m able to pull the shaft out?
I don't need to damage the bearing, right?
I found this tool: Wheel Bearing Removal Kit - Biltema.no
But it requires drilling two holes between the rings...

Is these correct tool then:
VEVOR Blind Hole Collet Bearing Race and Seal Puller Extractor Kit, Slide Hammer Pilot Insert Inner Internal Bearing Removal Tool Set, 10 Adjustable Collects and Counterstay, 16 PCS | VEVOR UK
???
I can't picture what this looks like—will the shaft be sitting in the hole of the bearing, or will it be empty so that I can pull it out?

Re: z750L: Repair starter clutch
10 Jun 2025 02:36 - 10 Jun 2025 03:16You need a "three bolt" puller to remove the gear (OEM parts puller 57001-319 and adaptor 57001-317) the adaptor 57001-317 is available from Partzilla and Johnny's and is cheap (as I understand it the adaptor fits between the puller bolt and the shaft to prevent damage to the shaft) you can use a generic "3 bolt puller like the one below as the OEM one seems to be unavailable. The diagram also shows how the three bolts attach the puller to the gearI have read trought the document:
KZ 650/KZ750 four starter clutch repair. - KZRider, KZ, Z1 & Z Motorcycle Enthusiast's Forum
I could not catch he was talking about a spesical tool for bearing pulling? The only special tool I can see you need is to pull the gear on the clutch side (as far as I can tell you would only need the bearing puller if replacing the "right side" bearing which you don't plan on doing)
He is mentino that it can be handy to have spesical tool for the main gear clutch (I had one when I replaced the friction plates, but have sold it..) For the cost it's best to get a "clutch holder" rather than risk damage to the basket
If I understand correctly, I need to take the bearing out on the right side before I’m able to pull the shaft out? No - the bearing will come out with the shaft (knocked through from the left side) once the gear and bearing retainer are removed
I don't need to damage the bearing, right? Correct
I found this tool: Wheel Bearing Removal Kit - Biltema.no
But it requires drilling two holes between the rings...
EDIT: "note to self" once you have bought tools (clutch holder) hang onto them, you never know when you may need it again and in the long run it's cheaper than buying again

Thanks! I’ve now ordered the adapter (57001-317) and the Faankiton 21-in-1 Bearing Kit, so I should have the tools I need.? 
In the meantime, I’ll remove the exhaust, drain the oil, and take off the clutch plates and housing on the right side. That way, I’ll be ready to open the left side once I receive the tools.
I’ll be working outside in a carport. I was thinking I could just reattach the right and left covers, along with the oil pan, using 2-3 bolts when I’m not working on the bike. Since everything inside is coated in oil, corrosion shouldn’t be an issue?
The bike won’t be exposed to direct rain.

I found a serie of videos on Youtube:
1982 Kawasaki 750 Ltd L (Part 8 Starter Clutch: Step 4 Final Step)
He is just tapping out the shaft with a weighted hammer?
