I am trying to restore a Kart which I have been given. I think the engine is a KTM 250cc?

Question

There is a bottle of oil attached to the engine via a pipe. Why? and what mixture of petrol and oil should I use. I am only playing about on it and not competing.

Answer 1

usually a bottle of oil like that can be used to cellect blow by oil from the exhaust or to lube a chain drive system. depends on whether its a racing style kart with an overkilled engine or a backyard kart. your premix should be between 6-10oz's pergallon.
