I have some questions, I have not orginal carbs I have Mikuni VM 24, orginal 650cc, but I have 750cc with 810cc bigbore upgrade.

Pilot: 17,5
Main: 112,5

Needle raised to second highest posistion.

4 to 1 exhaust and pods.

I’m 90% happy with the performance, only a issue in mid range throotle, off idle is quite okay.

When I install the air jets, what should I do with my current setup?

HI, Gordone.
If your bike was stock and you remove the airbox you would simply fit the air jets and increase the main jet a size or two.
If the needles had been raised and the pilot increased to compensate for the pods prior to fitting the air jets then they should be put back to stock and that would be it..
With your 810 i don't know what has jetting been altered and for what reason and i also think the 24mm are on the small side for that capacity and would recommend fitting 26mm from a 900 or 1000 to get the full potential from the big bore..
Having said that, with what you have i would fit the air jets first and see how that goes, the needle probably wants to go back to stock setting also i'm sure the pilots should be 15 and not 17.5 so it looks like that has been done as mentioned previously to compensate for pods and they most likely want reducing too.
Only make one change at a time though so that you know what affect it has.
Regardless of any other changes the air jets will be doing their job and any extra fueling needed will be for the capacity increase.

I have now moved the clips to 2th posistion (see picture below), before it was at 4th posistion.

These is the only adjusment I have done... is it stupid todo it, should I leave with setup I had?
I’m feeling that is wrong also since I have installed the air jets.

My thinking was, install air jets and lower the needle and see how its perform and then take it from there....

Is these stock needle posistion?

Gordone.
The clip is two slots too high .
Standard position is slot 4 counting from the top and it should be returned to that.

Ahh from top... then it was as stock position then.

You suggest I try to run the engine without doing any modification then or shall I go back to 15 pilot jet?

All settings should reman stock apart from the main jet.

Still when I have 750 with 810 bigbore and using VM24 carbs ?

Just a little update on the choke plunger repair service.
I can now repair pretty much all rubber tipped MIKUNI plungers of both 8mm and 10mm diameter heads which covers most Kawasaki, Suzuki and Yamaha machines including CV carbs. 
Hopefully this will also be of help to those running KZ and non KZ machines where these components are obsolete and no longer available new.

 

Test drived first time today with the jets.
seems to have nice performance increase

before it was not going smoth with midle throotle (steady) and high RPM typical on highway, today it was perfect in whole RPM range and throotle range.


have not checked the plugs yet.

Ride Report....... . Last year I installed Zed1015's Air Corrector jet kit and was really pleased with the improvement in drivability on my 1980 KZ1000.  Over the winter, I sent my OEM Choke plungers to Zed1015 for service. The improvement is dramatic. The bike transitions from low to mid to top end flawlessly. I highly recommend his services/product.......

Yes! Always been a fan of Croz and it was a very pleasant surprise when i got his email .
Hopefully this "Major coup" might bring a bit more awareness to the plunger wear issue and lead to more than a set a week or so coming my way or maybe i should end my plunger repairing career on a high
