Assuming your Oil Smells like gas?

Need to change your oil and filter and stop leaving your gas petcock lever on after riding, shutting off engine, and or during transport[img]i/expressions/face-icon-small-happy.gif[/img]

Also, weak Choke plunger springs can make your machine foul your plugs & add to problem of flooding carbs/cylinder.
