What can I do to stop the black goo from coming out of the exhaust? What is it? Unburnt fuel ? I've used a 32:1 mixture and now runnung 40:1. any suggestions? :whoa:
Sandman 2.0 said:I'm not a big fan of lean oil/fuel ratios. I run my KDX at recommended 32:1. I get spooge even though my bike runs great. I have the jetting leaned out. when I tried leaning it more to cut down on spooge and smoke, it bogged badly and ran like crap. Current plug reading is about perfect with some spooge and smoke. I think KDX's are weird like that. I have stock pipe and silencer. I always suspected the stock silencer collects oil and causes some excess spooge and smoke.
I run 50:1 in my 94 engine

Just one question. Why? I'm 99.9% sure that the manufacturer of that 94 engine suggests a ratio of around 32:1.
Oh, it's true, all right.whenfoxforks-ruled said:I surely do not buy the story that all 2 strokes produce spooge, sorry.
whenfoxforks-ruled said:NCRFC, got any data to back up the 300 percent statement? Well, except amsoils bs. What do these bikes do with all that extra gas that lowering the mix ratio puts in? Put smaller jets in? That would be a capitol idea, especially giving most of these are rider error or a mechanical issue somewhere. Far from perfect, but working at it every day, Bob. PS, I am really thinking stupid this morning about a friendly wager on one of these poor kdx spooge blowing things.

All 2-strokes burn their lubricating oil. Therefore, all 2-strokes produce burnt oil residue, since no oil just "disappears" when it's burnt (Law of Conservation of Energy). Some engines produce less observable residue than others, depending on state of tune, amount of oil, type of oil, etc. but every 2-stroke produces it.
Unless, of course, you attempt to run straight gasoline instead of pre-mix...... :)
I feel sure that if Al Gore understood what a milestone of a bike the H2 was, even he wouldn't mind the smoke. Just wish I had one too.Simmons1 said:If you want to see spooge and clouds of smoke you should see what comes out the back of my '72 H2 750. The H2 would bring Al Gore to tears.
flyingfuzzball said:wrong law. you meant the law of conservation of matter.
