Yet another project

Bike had spooge all over the swing arm

Someone is jetted a bit rich. I get that some times after a long ride on my YZ, but I also intentionally mix rich...

Your fuel oil mixture has no relation to exhaust spooge.

^Exactly

I meant jetted rich. I am jetted rich, but I don't mind it. I will properly jet it when I have some free time to mess with plugs and carbs

So a rich oil mixture will not spooge an exhaust?

Then what does?

rich jetting

A properly jetted bike will not spooge nor foul plugs.  I purposely have mine jetted on the rich side, and get just a tad bit of spooge on the exhaust tip.  I've never fouled a plug, in fact I only change the plug once a year, just because I feel as though I should.

Pick a ratio mixture and jet to it.  A bike running 24:1, jetted properly will not spooge, the same is true of a bike running 50:1 if jetted properly will not spooge.  We can argue (discuss  ) the atributes of the different ratios all day, but in the end a properly jetted bike will not spooge.

fuel and oil mix will also affect spooge out the back side. if you run it 32:1 and your a slower rider or arent on the gas much you'll get some, i use to run it like that but ive switched to 40:1 cuz im slow enough to get away with it. IF i ever get to inter speeds ill be changing it up. just my .02 im not a motorcycle tech but i did sleep in a holiday in

I am jetted rich but have never (knock on wood!) fouled a plug. I get the spooge on the end of my swing arm after a long trail ride (low RPMs) and not so much during or after a race, like the above posts said.

I ran my RGV 100:1.  Those motors are different though.  they are autolubed and designed to be run like that.

Na sorry motoman, have to disagree there, your fuel oil mix will not have any bearing on exhaust spooge, it's solely down to your air fuel ratio.
If your bike oils up at low revs or if you're just putting around then your pilot jet or air screw is incorrectly set.
You could run 20:1 and still lean your pilot jet out enough to melt your piston if you wanted. Or you could run 150:1 and jet way rich and you'll get spooge (along with a siezed motor i'd imagine)
Spooge and fouled plugs = too rich jetting.

If your  bike is jetted right it wont spooge . Gas/oil mixture has nothing to do with it . its all in the carb jetting

You fellas know how to plug chop?

You guys are crapping on my build thread!  I'm sure the guy had it jetted rich, it never stopped smoking and things weren't helped by his inability to get on the pipe at all to clean the bike out.  He was a danger to himself and others on a national caliber track like that.  Underground is a rough, rutted, loamy, big jump beast of a track.  He should have been putting around the 50 track. 

I go to pick up my suspension and other parts this afternoon, it should be back in one complete piece tomorrow night!  Then hopefully the first test ride to line everything out Thursday afternoon.

I'd be riding mine too this weekend but I have to go to Phoenix to waste some government funds for a group of guys who can't answer emails.

[Shawn36]

I got everything in one place and finally started putting it all together.  Like usual the lighting and camera on my phone are all horrible.  Please excuse the mess surrounding the bike.  It should be all ready to go by Friday afternoon and ready to ride this weekend!  Yes yes I know..  please pretend the 450 next to it isn't there..  or at least that it's clean.

The bike as it sits.. camera washed out the color pretty bad
