Maybe not the dirtiest ever...but close

Check out these pics from my carb cleaning today of a 2002 recently bought which had been sitting for...a summer? Who knows... Seriously...what is wrong with some people to let a bike get THIS bad?

Re: Maybe not the dirtiest ever...but close

a few suggestions.....bike newly purchased used?

a valve clearance check
purge the fuel, rinse the tank, check for rust, treat as necessary
check the petcock screens and ports
add the Kaw rail fuel filter
run some Seafoam after getting it running and carbs sorted

Properly clean those car potatoes...looks like a combo of rust and water in the bowls. The pilot and fuel paths will require some major attention, methinks.

Pics should be in a Stabil sales advertisement....what happens when you DON'T use....

Hummm.. That ooze in your carburetors looks like the same slime from ghostbusters 2...

The question is...

A little more info:
The bike wouldn't start...shocker. Seemed like it wasn't getting fuel...as it would turn but not ignite. Changed the oil(ALWAYS the first step for me when buying a used bike), then swapped the carbs from another EX(these ones I know were clean) along with the fuel tank from another ex(which I knew to be clean w/ working petcock) and it fired immediately. Couldn't open the gas tank as the lock was corroded shut. Took off the petcock...dumped the nasty fuel. a cleaning is in process as there are little rusty towers on the bottom.

Followed the wiki article to the T today with these carbs and used an entire bottle of carb cleaner spray on them. All jets seem to be clear now...the bowls move freely...etc. Won't know of course how well I did until I have them back on and fire it up. It HAS to be better than it was at this point...and for the first ever time taking carbs apart and cleaning them I think I did pretty well. That wiki article is GREAT!

Haven't gone so far as a valve check...but can't hurt as it has 18K on it.

Petcock seems....decent. It will get a cleaning also with the tank as there was some nastiness on it. There was an inline fuel filter installed on this one...but when removed the lines had gunk in them so it will be replaced, along with all the other fuel lines as they are gunky and old.


Tell me more about syncing carbs...does this need to be done after each time you take them apart?


I'll be starting a thread in the Mods & Upgrades section tomorrow with pics and the whole story - but thanks for the suggestions - much appreciated!

Re: Maybe not the dirtiest ever...but close

thanks for the advice! I will take a look at that tomorrow night when I re-assemble. looking on both the intake and exhaust sides of the engine with the carbs and exhaust removed I can tell this bike wasn't running correctly for a while. seems to be a lot of carbon buildup...but I could be wrong and it be normal. I'm trying to figure out why there is so much oil everywhere inside the air box(more than I think should be there but again I could be wrong)...seems like perhaps the breather that goes from the top of the crankcase into the airbox may be the culprit.

I did the recommended 2 1/2 screws out from bottom for the...pilots? - is there an EX specific article I can read about what this does and how to tune it?

I'll report back tomorrow evening with results. as I said - it can't be any worse!

Re: Maybe not the dirtiest ever...but close

possible the PO overfilled oil? its habitual with some folks (more = better....NOT!)

hose top of airbox is the PAIR VALVE hose, the crankcase breather hose is at the bottom/front of airbox.

there may be tuning info in the wiki, or carb threads, surf around.

Good luck with startup, post results.

Re: Maybe not the dirtiest ever...but close

Oh here's one more question - think the floats need replacing after seeing this pic? Cleaned them good with the carb spray...and they were moving freely...but you be the judge.

"Oh here's one more question - think the floats need replacing after seeing this pic? Cleaned them good with the carb spray...and they were moving freely...but you be the judge."

inconclusive photo ...the needle viton tip would need to be inspected to properly make that call. Since you ARE replacing the bowl orings (are you?) anyways...I'd opt to do complete carb kits whilst off and apart. I'd think you want to do this ONCE and be good for a long time going forward. Gambling on $16 carb kits just not worth it.

Re: Maybe not the dirtiest ever...but close

These photos ,while certainly the extreme show what happens to fuel (especially Alcohol blends) that stay stagnant for a while. Imagine just 1% of that in your carbs.

So get two of these and take all the guessing out of it?

Anything missing from this kit I'd need?

Thanks again for all the help.

Re: Maybe not the dirtiest ever...but close

That's the one. Check Parts-n-more. They have the best price on the carb kit that I could find. Also they have a petcock rebuild kit if you have any doubts there. Since your replacing the fuel line now's the time to switch to the fuel rail filter kawa p/n 49019-1085 (see wiki).

Re: Maybe not the dirtiest ever...but close

How do you remove the little valve pilots for the rebuild kit? Do they just pull out?

Please clarify "valve pilots".....perhaps you were not referring to the float valves which i addressed.

Re: Maybe not the dirtiest ever...but close

It is the float valves...as you mentioned and as I showed "gooped" in the picture. I will attempt to pull them out tomorrow and see if they will release. I have one rebuild kit and need to procure another.

Re: Maybe not the dirtiest ever...but close

Yup - pretty sure they need replacing. I have two of the k&l kits going in this week.

Keep in mind these look like this AFTER being cleaned with a LOT of carb cleaner. They pulled straight out....with needle nose plyers and a LOT of effort(cursing)

Re: Maybe not the dirtiest ever...but close

OK, they are a mess. As part of your cleaning process pay extra attention to the needle valve seat (where the rubber tip contacts). Use Qtips, the ones with paper stems, not plastic as they will melt, and carb cleaner until they are spotless. DO NOT stick anything metal in there or you will scratch the seat and ruin the carb. Clean, clean and when you think they are clean, clean them again!

Re: Maybe not the dirtiest ever...but close

bad news - I'm going to have to split these methinks.

I was cleaning out the float holes(with carb cleaner and q-tips as recommended) and then I blew air through the hole to evap and move the carb cleaner through the system...and when blowing them out...some white dust started coming out of the lower fuel hole(inlet). Looking in there it's pretty nasty. I could try cleaning it out with a lot of carb cleaner...but I think splitting the carbs apart so I can really clean it out is the better solution.




So ducatiman...I guess the only question left is how much you'll charge me to clean these suckers...with me providing the rebuild kits(already have them in hand)
