You should never ever run an engine low on oil, especially a bike engine.

The pistons and cylinder walls in modern engines are lubricated by oil splash caused by the crankshaft rotating in the oil pool. Low oil means no splash.

The oil also acts as a coolant in some of the hottest parts of the engine where water or air cannot be used.

In a bike the engine oil also protects the gearbox.

Don't scrimp on a couple of quid by not topping up your oil, you'll lose out in the end.

Unless like me, you have lowers and they block the sight glass :(


I think the main reason they recommend you run the engine for several minutes then leave it for several minutes is;

Warm engine for several minutes:
Warm oil is thinner, easier to see in the sight glass.

Let it sit for several minutes:
Allows the oil that has been splashed around time to settle back into the bottom of the engine/gearbox.
