I was riding yesterday and my 250R went dead and wouldn't start so I take out the sparkplug and it has oil all over it. So I go get another one. 2-3 hours later same damn thing! Please help, what could be the problem. I'm mixing Klotz and 32:1
Thanks,
Brandon

 

Sounds like you are wet-fouling plugs. Is your air filter clean? Did you do any car adjustments lately? Are you using a BR8ES or BR9ES, or did you change oils or do any other mods? What is you main jet size and needle position at?

Go to my site below and click on the NGK spark plug link. There is info on plugs and why they foul. It is very informative.
