Crankcase Oil Fill Level

2016 Bonneville T100

To set the oil fill level, should the bike simply be leaning on its kickstand, or placed vertical? The Maintenance Handbook doesn’t say and it makes a big difference in the sight glass !!

 

Thanks for your response Joe. And I beg your pardon:

In the Owner's Handbook (p.69), there is not a whisper about bike position. However, in the Service Manual (Lubrication System, p9.9), it says "The motorcycle must be level and upright when checking the oil level." I just caught that and stand corrected. And btw, I made a very nice jack for lifting and stabilizing the bike at any level.
