• Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

WHY is this plug so foul?

Anyone want to guess at the issue here? It's obviously fouled, and very oily. The bike smokes like a demon on cheap cigars. Now, for more info. It's a TE511, 2014 model with 900 miles on it. It's going in for evaluation, up to Hesperia where ZipTy Racing very smart people will evaluate.

In the meantime, I'm just fishing for input on this situation. Lost a bunch of oil, but never went dry. Turns over fine, and runs great, until all the oil that's entering the combustion chamber finally fouls the plug.

So.... where is the oil coming from?

Here's the plug:

If anyone correctly guesses the REASON for this nonsense, well, I don't have any prize money or anything. But if you're bored, and you correctly figure it out, I'll just be really impressed with your analytical skills. I monitor this thread... so I'll answer any questions.

Excess oil from the emissions routing? (getting pulled in thru the filter housing)

That sounds pretty good. Just don't know. The oil was somehow forced where it wasn't supposed to be in the quantity required to do the damage. Or so I suspect. I should know next weekend for sure.
 
Have you dusted the motor, maybe airbox/filter not sealed properly? Might be coming through worn rings, sounds like it nearly seized from your kinked hose problem, might have starved the motor of oil. Do you know how to do a compression test?
Maybe worn valve seals?

I wish it were a 2 stroke, then I'd have no cam issues and other cracked parts due to heat problems. The source of oil causing the fouling is still a mystery, but I'll know by week's end. Then I can say exactly WHY this happened, so other NEVER have it happen to them.

Four stroke TE511. Lots of good reviews on the bike. I killed mine. When I break something, I really do it right.
 
Your plug is oiled because the kink in the oil circulation system hose caused the oil to get backed up into your air filter. That cause oil to be sucked into the engine, fouling the plug.
