Would worn reeds cause the carb to pee? I have adjusted my brothers float several times and the needle valve looks good but it keeps peeing no matter what I do. I'm thinking the back pressure is causing it.... I haven't tore it down yet but was wanting to see what you guys thought. Also, the airbox vent is very wet along with the swingarm under it.

No. Well, IMO and all that HHS.

All other things considered to be OK...like none of those vent lines is plugged?

The needle valve can look good and the needle valve seat can look bad....

Check that crappy pin that holds the floats to the fuel valve. That pin has come out during installation, thus pissing gas all over

I don't think worn reeds would allow enough a/f mixture back into the carb to make it pee.

Check the needle and seat carefully. If you have a maginfying glass or eye loops they can help in finding flaws in the needle and seat. My 04 was pissing itself silly last spring. The second time I took the carb apart I found a large slimy ring of something around the needle seat. I used a q tip and contact cleaner to get it out. No problem since.

What?? You didn't use my wet-n-dry/Q-tip (or cotton swab if you must) method?

I'm hurt! Boo hoo hoo hoo....

Backpressure? I let that one alone...but if you've never put your hand against a fully functional and properly working carb intake bell while the engine is running...you might try it sometime.

All sorts of backpressure!

How would that translate into a force against liquid fuel? It wouldn't. Whatever of it gets into the bowl is going right out the vent tube(s).

It's a carb needle/seat/float problem.

Well, maybe a wonky kickstand it you're 'parking' the bike.

Alas, in my search for the KDX Grail I have failed. Tell me about the wet-n-dry/Q-Tip method. Q-Tips must be good for something since you are not supposed to put them in your ears. (I read that on the box).

Seriously, I would like to hear.

That label is as bad as the one I got the other day on a bag of salted cashews..... WARNING: MAY CONTAIN TRACES OF NUTS... ??? WTF ???

Grail? Is it missing? Dammit!! Not agin!!

The Wet-N-Dry Q-Tip Method:

Cut a strip of wet-n-dry sandpaper..the black stuff...a bit less wide than the swab itself. Loop it over the top of the swab, wet with something (alcohol will do..as in 99% isopropyl, not 70% rubbing), insert swab into seat, rotate against seat with light pressure.

The alternating abrasive/swab surfaces burnish and wipe clean the seat.

Start with a piece of 400, finish with 600. Change the strip orientation to the swab to keep fresh grit applied to the seat.

Don't get carried away with it.


Why waste time reading instructions on something like a swab? I stick'm in my ears all the time!

Huh? ...say What? 'eh???



p.s. Ever looked into where cashews come from? A plant related to poison ivy for one thing...and they really don't seem too nut-like.



And then read about the caustic junk that's inSIDE the things..used in varnish, insecticides, and paints. It can blister skin on contact!! ...which is why they are never sold 'in shell'.

An argument could be made they aren't even nuts!

Weird... Looks kinda like an apple havin a poo.

Nasty poo indeed...

..and you're the one eatin' it!!

Who's talking? I like cashews a lot myself. I'd rather not know where they come from. Sort'a like my hamburger. IT comes from the STORE!

Thanks, CC. Did a google search after that and it was a pretty good read. Sounds like an interesting plant. From what I read, it sounds like the raw cashews are supposed to taste better and be better for you than the roasted ones. Texas is darn near tropical (tropical = HOT) :-) so I may have to see if I can grow one.

Cashews come from a can. They were put there by a man...

Uh.... carb peeing anyone?

Carb peeing, apple pooing...... Close.







Sorry bout the jacking.

On the air box vent hose, do you have the transmission vent hose tucked into it? On the carb, check the float level and valve seat. Try it with the petcock on and off, how far does it have to be leaned over to trickle out, does it stop if the petcock is off, etc.

I have taken it back to my brothers house so I don't have direct access right now. All good questions though. I have never had the issue with either KDX's I have owned so it is new to me other than what I have read in these posts. It's all in the back of my head but the airbox swingarm being wet has me scratching my head. I want to get him some new 607 reeds too... not that I have seen what he has in there but it's a 90 model and proly worn out. He has no problem staying up with me.... that thing just runs!

Good idea on the wet-dry sandpaper and q tip. Sounds like it would be great for removing oxidation and gunk off the needle seat.

Would valve grinding compound - paste do the same thing or is it too coarse?? I have never used it, so I am just wondering out loud.

I have used a "lapping compound" that is a finer grit than the valve grinding compound. I'm sure it would work but might be more difficult to remove residual when you are done.

Why would it be more difficult to remove?? Again, I have never seen it, so I have no clue on its properties.

Thanks.
