2002 KDX220 - Puking Up A Little Spooge
Hi, recently I have gone out on some rides which are maybe a little too advanced for me and I lug the bike around in first or second on single track. After a long day it looks like my bike pukes out the exhaust port onto the pipe a bit. To me it's not excessive but I would still like to get it taken care of. I think this happens when I ride it in 2nd for a while and then revi t to 'clear it out' as someone told me to do. The spark plug never fouls and the bike runs great. At least I think that.
I am going to take off the pipe when I get a chance and check the condition of the o rings and metal gasket, but wanted to check here as well for any advice.

Looks like you need to do some jetting work

That's very common for a bike that has bad o-rings and/or a bent head pipe.

Check out the parts diagram.
Possible causes are as SS109 mentioned.
worn o-rings
worn copper crush gasket
ALSO: bent pipe, causing improper mounting angle
ALSO: steel pipe will wear out the aluminum mounting area if allowed to go unchecked for a long time
glob of silicone is a common repair attempt when the area is damaged
Just for the record, one drop is too much. The bike has an issue. Good job to inquire about it.

Thanks everyone. I will inspect and order parts as needed. Hope the pipe is not bent, not really prepared to deal with that. I always wonder how the pipe stays mounted properly between the top and bottom of rear compression stroke range.

Keep in mind that until you fix your spooge issue, sealing the pipe to the head just means that oil is going to be deposited in the expansion chamber/silencer, so it may look like your problem is solved for a bit, until the pipe starts spitting it out the back (or more frequently out the union between the pipe and silencer).

Don't forget the springs. Not very expensive. They do get old and stretched. Sorta like some KDX riders!!!

Yes, get new springs, too. Good idea!

For now I will be ordering new o rings, copper washer, and springs i guess although they seem good to me, and have added some hi temp permatex over the current orings in the mean time.
I like riding in second, but maybe i'm not at that speed yet and need to run first to stay in the powerband. I may try opening the air screw when putting around like that and see how that goes.

It's not the gear you're in or the air screw. You should go through the jetting guide in these forums. That's a lotta' puke coming out.

Goal was to go through that guide the first time i do a rebuild since that is one of the first instructions. I have the RB Carb and went a size down on pilot clip and main from how it came with the recommended settings from Ron for my mods and elevation.
