My KTM manuals say to check the oil level on my various KTMs when the engines are at operating temperature and have been switched off for around a minute.
Can anyone explain why the level is substantially different when it's hot than cold. I can understand a small difference due to the oil expanding when hot but not the amount it does.
For example, when the engine's cold and the bike's on level ground there's no oil showing in the sight glass but when it's hot it's at the top.
My GS was always consistent whether hot or cold so it can't be that oil expands by 25% when heated from 20 - 80C
Any thoughts to explain this?
