F50 white smoke

[Den]

I have an F50 four stroke which gives a constant trail of white smoke out of the exhaust. Engine performs fine and all cylinders have good compression. The engine is nearly 10 years old but well looked after. I have checked oil level and looked for oil contamination in fuel all is Ok

its probably just a little oil getting by the rings and getting burnt in the combustion chamber. i wouldnt worry about it.
