rocket blows white smoke on start up occasionally?

[Hipporider]

My rocket blows white smoke when you start it from cold occasionally, but not always!anyone know why it would be intermitent?Valve stem seals? She's only done 12000klms.

Blue smoke is oil,either rings or leakage thru valve stems,white smoke is coolant,head gasket,cracked block,anything that will let coolant leak into the chamber. Check your radiator fluid to see if there's any oily stuff floating around. Hopefully I'm wrong........Like Mike says in the next message,could be condensation...

condensation I reckon mine does it too on days with a heavy dew.

thanks fellas, thats something for me to look into.Being intermitent, the condensation argument bears weight as if there was a coolant leak you would think it would do it more consistently.Mikeg , does your bike do this even when garaged ,like mine?

certainly does
