Good Lord... hard to believe that somewhere around you in IL there isn't another KZrider participant that wouldn't be willing to do this with you for the cost of their gas money and lunch..... just sayin' $300....? Screw that.

Ok then someone give me some names of good carb cleaner that works and how to go about cleaning them.

Cleaning carburetors is easy. The same thing is done 4 times on a lot of stuff & most parts only go back together one way, so it's kinda hard to mess up. use good fitting tools, your eyeballs & common sense. 4 plastic divided lunch containers are handy. If the bowls n stuff don't look too bad, then you may not need to separate the carb bodies to soak them --- just spray carb cleaner to make sure the orifices are clear. But soaking them in Berryman's professional cleaner dip will ensure that they are clean.

Expect to replace the o-rings & gaskets. Harbor Freight metric nitrile or viton o-ring kit. or eebbaayy etc.
Z1Enterprises.com or the Kaw dealer will have o-rings & other stuff.

Here's my thread on some carbs I did.

Don't assume a new battery is good --- test it.

Use good fitting tools, your eyeballs & common sense. 4 plastic divided lunch containers are handy for keeping the stuff from each carb organized & separated from the other carb parts.

Expect to replace the o-rings & gaskets. A metric nitrile or viton o-ring kit will have some suitable sizes. Harbor Freight or eebbaayy or elsewhere. Z1Enterprises.com or the Kaw dealer will have o-rings & some of the other rubber stuff, such as the starter/choke plunger caps & o-rings and fuel Tee o-rings or rubber fuel Tee fitting.

How many jets does each carb have?

No offense intended, but you are wasting a lot of time and energy trying to work on your bike without a manual. You would already know the answers to most of the questions you ask if you were to simply buy and read the manual, PLUS you would gain a real understanding of your bike and the various systems on the bike. No one has ever regretted buying one, they are worth their weight in gold.

Folks on this forum are happy to help, but answering elementary questions that show the owner hasn't done any research on his own is a bit tedious for some of us. Ed

i have stated time and time again in other posts i DO have a manual. its a clymer tho and no one is happy about that...im not gonna waste my time looking for a 30 some yr old manual because some guy said so......its the manual for the bike. what does it matter? it may not be word for word what the original kawasaki manual is but theres no way they are pulling this info out of their ass. they probably got the info from kawasaki?

If you go here: www.zedrider.co.uk/service--owners-manuals.html
You can find this: www.dropbox.com/s/ielbey7s4nwqc96/Z650%2...Service%20Manual.pdf

That's the 650B Kawasaki Service manual. From your front brake location, I think you have a B2?
There are going to be some inconsequential changes from the B1. (someone else please confirm?)
Also, the parts diagram on that zedrider page, or here: jarlef.no/Kawasaki/Series/Z/650/z650files.htm are so useful when searching for parts.

The reason Clymer and Haynes manuals aren't good enough is because they transcribe and interpret from the original manual or other sources. There are going to be more mistakes, transcription errors, and hand-waving in an aftermarket manuals. They try and simplify things that are already simple, and end up leaving out important information (ie like that there's an acceptable valve clearance range and not a single correct number.)

Sorry for all of this to sound like you're being beaten up, but the manual is really helpful, and it really is the right "tool" for the bike.

You're right. It doesn't matter at all. Enjoy your bike and good luck with it. Ed

Good stay off my posts ed. I'm gathering info first by asking some questions. U can't be patient and won't get off your high horse

The Haynes manuals are great actually, I much prefer them over the factory manuals. Lots more pictures, specs for the whole series and even the layout makes a load more sense to me. I never really get it why they are under rated here.

Blink, if have a manual and can't be arsed to even look at a carb exploded diagram and parts list before asking for help then the more experienced members here won't bother helping you. Have you searched through the forum for previous posts on kz650 carbs? If you have looked already and can't make any sense of it then you are out of your depth here and need to get it done for you.
