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.
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.
