The scooter has self-starter and autolub system to mix two-stroke oil with fuel.

The engine was lubricated via a separate tank for two-stroke oil, allowing the use of ordinary petrol.

Even then, in many cases, the rider would carry a bottle of their own two-stroke oil.

These, he knew, contained a premixture of high-octane gasoline and two-stroke oil formulated for cold-weather running.

Today, owners normally carry a container of two-stroke oil in the car for this purpose.

The two-stroke oil is ultimately burned along with the fuel as a total-loss oiling system.

"Don't worry," he says, "you're not going to smell two-stroke oil when you're eating your panini."

This model lacks an automatic lubrication system thus two-stroke oil must be pre-mixed with petrol.

Increasingly, these models were fitted with an early two-stroke oil mixing pump, fed from a reservoir incorporated in the petrol tank.

It has autolub system which omitted the need for premixing of two-stroke oil with gasoline.
