Please can anyone tell me where oil level should be Vs sight glass on an R1

Thamks Greg

should be top of the glass plus 250ml

or

top of the glass when the engine is ticking over

Here's a question: I have seen 2 different tilt angles of the R1 mounted in BECs: either with the bottom of the sump horizontal (which I think is more faithful to the orientation of the engine in the bike when it is stationary and as seen here) OR with the sump gasket horizontal (as I have on my BEC).

Do you think there will be a significant difference in the oil levels indicated by the sight glass in these 2 cases? Hoping not (otherwise I guess I would have to check the 'true' overfill level by tilting my car over)!

I've looked at them in the bike shop and they check the oil with ithe rear up on a paddock stand which puts the engine at a different angle to standing on it's wheels and they haven't had any problems with one yet.

Thanks - had visions of having to tilt the car over on one side in order to achieve the 'normal' orientation
