Choke plates removal

Hello. I do want vapor blasting my carbs. I need totally disassembly every steel part, especially zinc plated to keep it from rust. I did everything, but screws that hold choke plates needs to be grind out with the dremel tool at the back, but the question is- is somewhere i can get those screws back?

These are throttle, not choke plates. Kawasaki/Keihin has never sold any service parts for them, meant to remain undisturbed.

I'd suggest to leave them be, simply work around them.

But if you so choose to remove, I believe they'll be 3mm, countersunk, stainless steel screws. Allen head, JIS or phillips head...your call.
Length not super critical...you'll need to cut to length and peen them in place over again. Also suggest using red Loctite on the threads.

Should be readily available from an internet hardware specialist.

OK. Thanks for helping. Throttle plates ... I think, I need brass instead stainless steel screw, easy to smash the ends to lock it there. Also, red Loctite. And yeah, I really want them to leave, but vapour blaster man said i need remove all parts that made from steel.

Removing those plates and shafts is a bad idea, no matter what your blaster man says. The chance of getting them re-installed in exactly the same position is effectively zero. He won't be the one who has to deal with the consequences of slightly out of position throttle plates. It will be your problem.

There are some things that shouldn't ever be taken apart.

This, plus the chance of bending the shafts or throttle plates while attempting to peen them in place with a punch. I imagine they have a special tool that does this during assembly in the factory.

I don't see any difficulties to reinstall them, the new screws will make them be in right position, it will not move anywhere with correct sized screws. It having slight movements to the sides when you wiggle the shafts, I think it's not that critical.

K-woppa - Thats why I think to use brass screws and 30mm piece of rod when punch it. Do you think it will bend anyway?

BTW....the throttle shafts are steel...the plates are not.

Regardless, I know too late now, but I believe you could have avoided this unnecessary procedure by simply capping off the carb venturi area from both sides. With a little effort and ingenuity your blaster could have worked around his needless requirement.

Pic example...these throttle plates went unmolested within my cleaning efforts with zero issues.

I'm just not seeing a need for removal, as your cleaner evidently demanded.

Thanks Ducatiman for advice, but I already took off throttle plates from shafts. All 4 screws been stripped. They easily came off, with left hand drill bit.
I've decided not to send my carbs to vapour blast, to safe some money, as I am buying dynojets along with k&n pod filters.
So, Ive just blasted them at home. Thinking two options - Powder-coating or urethane-ceramic.

Ok. So, the carbs been striped apart, blasted and painted. No problem with installation the throttle plates. I simply replaced original fasteners with m4x6mm brass screws. I've put red Loctite on the treads and I smashed ends of the thread. I don't think they will fall off...
