did a carb cleaning. took pics. i didnt need to take the diaphragms off so this is only the gas side if you will... but if your needles are all gummy and what not.. you need to remove the covers on the other side and pull the assy out and make sur eyou clean those needles up. so.

also... this is how i would do it. not saying i'm 100% right.. and if you play with your carbs you are responsible lol. This method has worked for me many times.

First, remove whatever you need to to see all the tank bolts. Then remove the gas tank bolts.

Disconnect the fuel petcock after turning it to the off position.

Disconnect the carburetor fuel inlet hose
http://i148.photobucket.com/albums/s9/camaroguy72/3.jpg

Disconnect hoses going to the airbox and the screws holding the top of the airbox on
http://i148.photobucket.com/albums/s9/camaroguy72/4.jpg

REmove the lower part of the airbox by removing the screws holding it down and whatever hoses are attached

Disconnect the carb vent hoses

Disconnect TPS on right side of carbs (sitting down on bike)
http://i148.photobucket.com/albums/s9/camaroguy72/7.jpg

Loosen clamps and pull carbs out of boots. I would cover the holes with paper towels or something immediately to keep things from falling in there by accident

Remove throttle cable bracket to make it easier to take the cables off, then disconnect the cables
http://i148.photobucket.com/albums/s9/camaroguy72/9.jpg

Disconnect the choke cable, pull it out of the bracket or some bikes just unbolt the bracket that holds it
http://i148.photobucket.com/albums/s9/camaroguy72/10.jpg

Pull the carbs off. Sit down somewhere with a can of carb cleaner and get ready to work
http://i148.photobucket.com/albums/s9/camaroguy72/11.jpg

Loosen and remove all the float bowl covers. They can strip easy, so i would recommend using vice grips to loosen them all up initially. works like a charm
http://i148.photobucket.com/albums/s9/camaroguy72/12.jpg
http://i148.photobucket.com/albums/s9/camaroguy72/13.jpg

These are the parts of the carb that interest you. If your bike isnt idling, the pilot jet is prob dirty. if its sputtering at the top end, check the main jet. If it floods or something, check the float needle as there may be crud binding it up
http://i148.photobucket.com/albums/s9/camaroguy72/14.jpg

Remove the pin holding the float in, something small helps.
http://i148.photobucket.com/albums/s9/camaroguy72/15.jpg

Remove the screw holding the float needle valve and remove if necessary... sometimes they are pressed in and not meant to be removed.
http://i148.photobucket.com/albums/s9/camaroguy72/16.jpg

Check the pilot jet after removing it. See if you can see light through it. 2 of mine were showing no light , hence the sputtering.
http://i148.photobucket.com/albums/s9/camaroguy72/17.jpg

Soak everything good and remember what went where. Sometimes there are different jets in the inner and outer banks and you don't want to mix those up
http://i148.photobucket.com/albums/s9/camaroguy72/18.jpg
http://i148.photobucket.com/albums/s9/camaroguy72/19.jpg

Blow some air through everything and reassemble. I cleaned my carbs in the little places with q-tips soaked in carb cleaner. that seems to work well with the tight spaces

Put everything back together and drink a beer

typically... you can pull them out of the boots and then loosenn them b4 installation. i've done that before when for some reason, i got the bike and the heads were stripped on the screws for the clamps lol. my superhawk was the same way thouguh... i have that 2ft screwdriver lol

Good write up Rob, +1 to a sticky for this.

Jesus, Rob, I asked for a quick rundown, you went overboard! Too bad you posted this AFTER I cleaned my carbs yesterday, would have saved me some time.

Some additional info:
As for the float bowl covers, a power drill with phillips head works very well to back them out, it torques them right outta there without stripping anything. I'd recommend starting them by hand and taking it easy with the power drill when putting them back in.

Another thing I'd keep an eye on is the tiny o-rings on the black needle covers (or whatever you call them), and also make sure your fuel strainer doesn't fall out when you pull off the fuel inlet hose.

Excellent write up, this should prove very helpful for anyone with a carbed bike. Probably a good idea to post it over on Kawiforums too, since a lot of people ask how to do this.

One other note: Remember to stick some paper towels in the now open intakes so you dont drop anything in there, cuz that would be no fun

n/m I see you got that in there lol nice write up

Nice write up Magician. Has this site ever had a "how to" section? I like it'd be quite helpful.

I haven't posted in a while, but I just read your write up. I'm in the middle of cleaning my carbs (among about a million other things with my jeep). Something I found helpful was to replace the float chamber screws with allen head screws. I stripped a few of mine even with the proper sized screw driver.

not bad not bad.... I take it you can run something through the tank to clean it out (seafoam or something)

Yep... first thing I would always do... either ALLEN head or NUMBER 3 phillips, which never strip unless you use a number 2.

So basically..... Yeah I'll be calling my bike mechanic. I like to think I am capable of doing some maintenance, but I've got to fold on this one. WAY over my head and out of my league of ability.
Awesome write up though Rob!

It's easier than it looks. I hadn't worked on bikes much before doing this, and it went pretty smoothly. There isn't much you can mess up during this process. I'm sure someone on the board would be willing to help you out free of charge, so save your $$ for other things instead of a mechanic!

Thanks for the tips. I plan on doing this when the season is over so if I screw anything up or find I need parts or something, I won't miss out on riding. Thanks for taking the time to write this up. At least now I have somewhat of a clue. :thumbup:

cant u just put seafoam in your tank?

yes, put seafoam in there and everything will be fine

If your carbs a dirty enough to run like shit, seafoam isn't going to fix it.

Exactly. Seafoam won't clean those clogged pilot jets out thats for sure. Sometimes the carbs get gelled up and in that case they are a PAIN to clean ... better off replacing pilots.

Also, a good idea to check for corrosion in the carbs on a bike that was sitting for some time when you take it apart. you never know!

I have an easier way to clean my carbs... which has worked GREAT in the past, many, many times....

1) scroll through phone - ROB BUSA
2) call
3) shoot the shit for a while, decide that Rob is MUCH better/knowledgeble with carbs than I am
4) Rob cleans carbs
5) Bike runs PERFECT (everytime)
6) Beer and good times for all..

BAM!! Proven process...

but it might now work for everyone... :cool:

PS- Rob, I picked up a CR500 that I might need the carb cleaned on..lol..

So to continue where I left off... for those wanting to do a complete tear down.. here goes.
First.. you need to drill out the caps covering the pilot air screws. Drill carefully.. too much pressure and you will damage the head of the screw.
http://i148.photobucket.com/albums/s9/camaroguy72/1-1.jpg
Second.. remove the cap and you can see the screw. Turn the screw in slowly and count how many turns you went in... write this down so you know where to set it again. You should tighten til there is light pressure, no more.
http://i148.photobucket.com/albums/s9/camaroguy72/2-1.jpg
Pull the screws out and they look like this.
http://i148.photobucket.com/albums/s9/camaroguy72/3-1.jpg
Some pieces may not come out of the carb attached to the screw.. so make sure you have everything. the air screw, spring, washer, and o-ring.
http://i148.photobucket.com/albums/s9/camaroguy72/4-1.jpg
NOw flip the carbs over and remove the diaphragm covers. there are 2 screws holding each one. remove them slowly as there is a spring under there that will push the cap off you dont control it.
http://i148.photobucket.com/albums/s9/camaroguy72/5-1.jpg
Remove the spring
http://i148.photobucket.com/albums/s9/camaroguy72/6-1.jpg
Take note, there is a little o-ring around this fitting. Make sure you get the o-ring.. or make sure it's not still attached to the cover.
http://i148.photobucket.com/albums/s9/camaroguy72/7-1.jpg
Pull the diaphragm out slowly. You do not want your hands on the rubber... tearing the diaphragm results in needing replacements and they are not cheap. Use your finger in the middle to slide it out.
http://i148.photobucket.com/albums/s9/camaroguy72/8-1.jpg
Here you have it... all removed.
http://i148.photobucket.com/albums/s9/camaroguy72/9-1.jpg
Now you need to remove the chokes. THere is a slide that is not pictured that is held down by a few phillips head screws. remove the screws and then unscrew the chokes. I use a 14mm open end wrench to get them started, then pull them out by hand.
http://i148.photobucket.com/albums/s9/camaroguy72/10-1.jpg
Now you can go to town and spray through the carbs ... blow everything out with air and then reassemble. THese next few pics are for additional help with the slides
When reinstalling slides, make sure the needle is lined up with the hole in the carb body.
http://i148.photobucket.com/albums/s9/camaroguy72/11-1.jpg
If you are in the market to change needles.. here's a tip on removing them. In this pic, you see what you would with just the spring removed.
http://i148.photobucket.com/albums/s9/camaroguy72/12-1.jpg
take a pair of pliers and pull the little plastic piece out. it has a tiny spring on the end of it that likes to fall out, so be careful.
http://i148.photobucket.com/albums/s9/camaroguy72/13-1.jpg
http://i148.photobucket.com/albums/s9/camaroguy72/14-1.jpg
NOw you can see just the needle
http://i148.photobucket.com/albums/s9/camaroguy72/15-1.jpg
remove it carefully and guide it out.. in this case, these needles were shimmed so make sure the washers dont fall out

this pic shows the aftermarket needle. it has a clip that lets you choose where you want to put it, the factory spacer, and a shim
http://i148.photobucket.com/albums/s9/camaroguy72/18-1.jpg
Here are the diaphragm parts once more
http://i148.photobucket.com/albums/s9/camaroguy72/19-1.jpg
ALso... be careful spraying carb cleaner on your diaphragms. The result is shown in this pic... pulled this out of a carb like this. bad one on the right, good on left.. although they both work fine still.

PM me with any questions or just post here if anyone needs more instruction in addition to the first part of the carb cleaning thread.

just to add in.. sometimes if there really crapped up , spraying carb clean may not remove all the debris and clear blocked ports.. if so the housings will need to be tanked.. if anyone runs into this let me know i have a dip tank and glad to help out.
also after the reassembley is done dont forget to sync the carbs..
