Spark plugs smell

  1. How shall the spark plugs smell? I wanted to be good with my bike so I've changed oil first, now I changed spark plugs and I've noticed that one of them smelled with fuel while another one had no smell. I imagine that it is a bad thing they smell different but which one is wrong and what may be the problem?
     
  2. How does it run? It's carbed, correct? You may have just twisted the throttle without it being running...
     
  3. It runs pretty good. It is curbed. The only thing I can complain about right now is a little bit of vibration at high engine RPM. I´ll give it a ride and I´ll check the plugs again taking care to not to touch the throttle. Shall it smell with fuel or it should have no smell?
     
  4. If one jet is throwing too much fuel at it, it may not burn it all?

    Maybe your carbs need to be synched. When was the last time the carbs were gone through?
     
  5. If it runs pretty good just don't smell the plugs.
    Rather - ride, enjoy, explore.

    That's typical.

  7. I would think it would depend on what cycle the cylinder was in when it was shut off. If it was just starting the compression stroke, I would hope there would be fuel on it.

    If they LOOK the same, your most likely good to go.
     
  8. if it smells like chicken you eat it...

    fish you .... well :stir:
