Oil pressure switch

[fazersharp]

So from what others are saying, the egg cup left in the galleries after several minutes after running the bike up to temp, is offset by the egg cup of expansion of the oil. When cold the egg cup that was in the galleries is now in the sump, and the egg cup due to heat expansion is no longer relevant. ergo, the level will be the same in both hot and cold scenarios.

With regards to my own personal experience, the light has come on, on only one of the ten journeys I have made since my original post, if the oil level was dangerously low as has been suggested, it was low for all ten journeys, but only lit the lamp once. In the interest of covering all the bases, I checked the oil as per the manual, and marked a line after seven minutes, and then checked it again after two hours, and there was no difference whatsoever in the level. I then warmed the bike up and topped up to the top line. On four journeys since, the light has come on twice.



Back to my original question, before I was accused of being an idiot, has anybody else had trouble with their oil light?

A new switch is £86, so I'll look for a S/H one, unless I can fix the old one.

I don't think anyone has called you an Idiot. Do not but a new switch - you do not need one, I can confidently suggest that there is nothing wrong with your switch .
Yes I too have had the same issue with a flick on of the light after accelerating (with fun) from exiting roundabout. I looked at the level and it looked all ok so I put in about an egg cup full more oil and since then have not seen the light switch on. 
I had replaced the oil and filled it up as I have always done but this time it was a cheaper oil - same spec but I put the oil on light down to to oil being thinner and more readerly "sloshed" to the back and away from the switch on hard acceleration.
