I put a new rubber gasket on the connection between my pipe and silencer, however, I still have oil spit out of this over my swing arm. Does this mean my carb is jetted incorrectly? I pre mix 32:1. Everything on my bike is stock. Will pre mixing @ 40:1 rectify this problem? I use Kawachem racing oil. Is it really safe to mix this 40:1? Thanks for the help

Premixing 40:1 will actually make things worse. You will be even richer because there will be more gas in the mixture. You are probably running too rich. Check out http://justkdx.dirtrider.net/ and the section on carb tuning for a good read on jetting, etc.

Good luck!

You need to make sure you're jetted right. Even if you are and you plug around a lot in the woods, you'll still spooge and leak there. The easiest fix is to put a zip tie at each end if the blue rubber gasket. It'll keep that crap from oozing out..

Try switching oils to Maxima SuperM it tends to burn more completely at a lower tempreture than most oils. Keep your ratio at 32:1, don't go to 40, Ensign is right. Realize that when you make a change you still have the black spooge in your pipe and silencer, so it will take a little time to get it out.

If the SuperM at 32:1 doesn't help, raise the clip on your needle one place.

Hope that helps

Bought some Super M today

I will try it as soon as I blow out my current tank of gas. Also will use the zip ties. Thanks to all for your input.

If you have an aftermarket pipe, the joint may not fit like it's supposed to....a turbine core II fits like c___p. In that case, even if you are 1/2 right on jetting, it may still blow past anyway.
