Exhaust leak

[Gomes-nz]

I just picked up a KDX200E3. I have only ridden it for about an hour. It has developed a leak of a black tar/oil from the exhaust where the silencer and exhaust meet. Also the silencer packing seems to be fill of it as well.

First thought is that it is to much oil - when I mixed up my gallon of gas, I had to measure the ounces of the side of the oil container, not that accurate, so I am sure it was less than 50:1. Better to be safer than sorry.

I am using AMS oil 2000. Will this problem affect the KIPS

Well, you definately need a better way to measure your premix. I used hitemp silicone on the pipe/silencer junction then added 2 tiewraps and no more leaks.
I do see some spooge out the silencer but after all its a 2 stroke. If you feel you have way too much spooge then you might be too rich. Post you carb size and current jets for more help. Sounds like it's time to repack your silencer huh?

If your bike is new then you are definately running too rich. Check out this link and go to Tech Tips to give you ball park jetting specs for your bike.

Thanks, I already have the repack in mind. Also I was told by someone else that it was too rich, it has a performance pipe on it. Will have to spend a little time testing it. tks for your help

I've also done the tie wrap thing and it works well. Tighten it with a pliers to get it as tight as possable.
