Oil pressure switch

[BBROWN1664]

No body has mentioned that when the oil is warm it will have expanded and therefore higher in the window than when cold.
Must admit I've never noticed the difference and anyway my light has never come on so I don't get concerned about it.
I still change the oil at approx 4,000 miles and check the level now and again, but have never had to top it up between oil changes. Bike now done about 55k.
Doesn't take much oil from first appearing in the window to going beyond the top, so a bit of care required at the final stages of filling.[size=78%]  [/size]

Expansion will be minimal. So ignore it.
Oil will be up around the top of the engine when warm rather than all in the sump. This is why it is LOWER in the window when warm and why the manual says to check it when WARM
