Well, we had gone a *solid* 10 minutes and decided to stop and check the map.
I was looking over Dave's shoulder at his 450 EXC and it was steaming pretty good. I just chalked it up to splash from a puddle he must of hit.
But the more I looked ... ummmm.....
"Hey Dave ... I think your bike is smoking pretty bad. In fact, it looks like it's ready to ...."
But I couldn't utter those words lest they come true.
And shoot. I forgot to take a picture. Rats.
We hurried over to his bike and could smell a burning oil smell. Oh crap. And we could see signs of oil splash on the side of his cylinder, under his gas tank, and on top of his radiator. We thought it might be antifreeze - but it didn't smell sweet like AF does.
Wed thought it might be engine oil but the smell was different than what you would expect from that as well.
Well, I turned my back for a second - and the next thing that I know - Dave has started field-stripping his thumper:
I dug in my big-a** backpack, broke out the latex gloves and an LED lamp and we started looking closer.
And it got weirder and weirder. We could find oil in the strangest places splashed onto the engine/frame and gas tank - but couldn't find the source.
Then Dave figured out "...hey, this is fork oil!! Oh crap, not again..." Which is why the burning smell was so funky - it was 5 wt fork oil on the header.
But a little closer inspection, I spotted the exit point - it was the preload adjustment bolt on top of his fork cap!
That's why the oil was ending up on top of the radiator and engine/frame.
Dave immediately said, "shoot, I'm still going riding." So I pulled out some paper towel and he zip-tied a "bandage" in place and we got back to riding! Of course, there was a tang of fork oil in the air the rest of the day .... <grin>
