How could this be?

[Tims500]

My right side cylinder stops firing some times. Pull the plug cap and I can hear it sparking. Plug and plug cap has been changed. I can smell the fuel, and got a whopping back fire a couple of times.

Any clues, never had one of these beasts before.

Tim...

Never mind. The plug must have been wet with oil. Because on a whim I dumped copious amounts of SeaFoam in the tank and presto, when it warmed up, it started to fire. Sticky needle valve?

Thank's

There are two types of Spark plug caps used on these bikes and the US models usually have the more complicate,"Resistor" type ones.These are more prone to corrosion and break-down.
