Dirty Carbs

Hey all, I just got an 06 500r with 8600 miles on it. By the condition the chain was in it did not appear to have been maintained. Not alot of miles so i figured lets get it up to date. I think I am going to tackle the carb cleaning myself but when i looked at them they seem like they may be leaking or is this normal for a carb?

Re: Dirty Carbs

They look like mine that are on my bike, maybe not as bad, but not normal no, basically raw gas on the out side of anything not good. Especially when it is supposed to be inside. but to make sure there is a problem clean them and have a look see I clean mine and with in about 25 hours I got gas on the outside again.


Edit: 25 hours or 24 lol not sure hour I mis-typed that but you get the picture.

Re: Dirty Carbs

right on, so what do you think is causing the leak? should i order a rebuild kit and just replace everything or could it just be the floats need to be adjusted to the 17mm?

Re: Dirty Carbs

Honestly could be anything, I am the least skilled carb person on the forum as far as rebuilding goes, but clean and see what is leaking first. and then take picture and ask Ducatiman he is pretty much the go to person at the moment on the forum.

Re: Dirty Carbs

Clean the carbs and see if they leak before you tear it apart.

Re: Dirty Carbs

are you just saying clean the outsides? I figured with the 8600 miles it would be ready for a carb cleaning all together. Again I'm new to all this but i figured it couldn't hurt to pull them out and give them a good bath.

Re: Dirty Carbs

+1 clean carbs first read how to do properly so your not wasting your time as many have done a lot,read post and wiki,looking clean not good enough,when apart you can check your gaskets,diaphram etc,add fuel filter,i have that year and close in miles and I had some carb issues from no fuel filter and sitting months from P.O,good luck,other than that my bikes been fantastic.. no the internals the important thing many little passages etc..P.s wait for saint ducatiman to answer its worth it...

Re: Dirty Carbs

I was refering to the outside oilyness of them simple windex and spray them off if you are concerned with cleaning internally them take them apart all good but, know what your doing first.

Re: Dirty Carbs

i have read the wiki post a few times and printed it out in a binder to have with me when I do it. Worst case we have a few good shops in town I can bring it to if I get stuck. I am worried about adjusting the floats... how hard it that step?

Re: Dirty Carbs

Ducatiman has the flu

Leakage indicates some internal work is, in fact, needed. The soiled carb bodies are secondary, the internal circuits, seals and adjustments are the primary objective (its ok to clean the bodies while carbs are removed).

The wiki falls short on some of the actual critical cleaning, setup and confirmation procedures.

Look at Cali4nias thread on his carbs....Mango's (within the thread) were leaking, which i corrected. I posted the apparent reason for the fault plus fix there. Though your cause may be different.

https://www.ex-500.com/index.php/topi...html#msg916554

Also search around the carb section here for some cleaning info I've posted many times in the past.
Surf and read as much as you can.

Float and fuel heights are a critical, fine adjustment. Pilot system needs disassembly and cleanout, and theres much more.

PM me if needed.

Re: Dirty Carbs

silly question, but, if the fuel petcock is left open could it cause the fuel leak issue?

Re: Dirty Carbs

Abra....a quick look at your leaky carb pic ......the cause could be as simple as a float gasket or deeper yet as in a high float level and/or a leaky float valve. I'd have to see them to accurately pinpoint.

The EX vacuum petcock should theoretically stop flowing when engine is turned off. In reality they can fail.

The combination of a failed petcock and a (internally) leaking float valve can cause hydrolock and ....left unchecked .....can fill the crankcase with fuel. Unchecked, in its worse case, leads to bearing failure from diluted oil. Just happened to a poster a few weeks ago.

The left one seems like more leaked from it but both look like they have leaked... i rode another ex ( a 94) and it had way more power on take off. Could the carbs be causing the lack of power in the 06? I'm thinking of swapping them out and see how the 06... i post when i find some time to swap them out....

Re: Dirty Carbs

Carbs control fuel delivery and that directly affects performance. :-)

I've done carbs for 3 members recently.....their "after" quotes include "flawless, amazing, runs fine no flat spots"

Do you think thats' just coincidence?

Proper functioning (or not) carbs can make or break your EX's performance.

Cut to the chase....clean and set them up. You are wasting time "swapping sets" to see the difference.

However, I do respect the fact that it is *your time*, so do as you wish.

Funny you say that. .... Guess what I did today. ... cleaned them up and got them back in. Is not ready for the road yet but it seemed to sound better, may be wishful thinking.
I should have everything done monday. I'll keep you posted.
