Unknown carb part

[dosfiddy]

Hey guys, hopefully you can help me with a predicament. I had taken my carbs apart to clean the other day and this little part fell out while I was flipping the carbs upside down. The thing is, I don't know where it came out of. I checked the exploded diagrams and couldn't find it.

2+ heads are better than one so if anyone could help me figure out where it came from that would be splendid. This came out of a 2004 Ninja 250r.


Sorry, the link was messed up.

Have you posted a picture of the part?

I've had my 09 carbs apart a few times and I don't remember seeing that part anywhere. Older carbs could be different I guess.

BTW... Can you add another picture that includes a known object within the picture so we can have an idea of the scale of the suspect part.

Kinda looks like a press-in needle jet to me

Here's a lame over the head shot & size comparison shot.

Does a press in needle jet fit underneath the main or aux jets? When this fell out both jets were out already.

See the pic above "Cleaning Process", even has instructions on which way it goes in.

Yeah buddy I'm right 8D

[dosfiddy]

Ah, I see it now! Thank you for the help.

Mtn Dew is correct, its the needle seat.

Its the needle seat and goes under the main jet. Beveled side towards the needle.

So that's how it happens, just turn the carbs upside down and the needle seats fall out and get lost.

Anyone remember that recent thread in which @azwillnj spent an incredible amount of time and effort trying to get his new-to-him 2007 to run?

And it turned out that his carbs didn't have any needle seats in them when he bought it! He totally proved that there's no way to get an EX-250 to run well without needle seats in the carbs (no matter how many times you clean the carbs).

The thread has some really good pictures of the needle seats on page number 4. http://www.ninjette.org/forums/showthread.php?t=98983

Just a tip: See the numbered link at the upper right of each post? You can link to posts instead of pages. Many people change their posts-per-page setting in the User Control Panel so that they don't have to click through so many pages to read things. It really helps bandwidth and delays too: load more at once, spend less time loading more pages for the same content with fresh ads (sorry, Alex). Unfortunately, the feature means that page numbers are mostly irrelevant because many people have different PPP settings.

I appreciate the effort but I'm an internet knuckle-dragger. I bang rocks together to make fire. My daughters laugh at me.

The only problem with linking to posts is that they only seem to list one post as opposed to making them the starting post on the page.

But yes, the needle seats just fall out if you aren't careful. They aren't press fit because they need to be replaced when they wear out.

Sometimes, that's a desirable thing. If not, click the link, then look at the "Thread" link right above it. That one takes you to the full thread AND scrolls you down to that particular post regardless of the page setting. If you didn't want to go through the trouble to click it and grab the other URL, the people you are sharing the particular post with can see and use the "Thread" link just as well.

You can fix that by changing the word "showpost" to "showthread" and leave everything else the same. It will link to that post within the full thread.
