Oil overfilled (by dealer!); damage?
I checked the oil level of my K5 650 the other day (following the recommended procedure in the manual) and was alarmed to find it quite high; with the bike upright the sight glass was completely full (it would show full just before I got the bike 100% upright).
The bike had about 100km on it at that point; think any damage was done?
I drained out the excess (probably 4-5 ounces) and checked the level after warming up the bike, shutting it down and waiting the prescribed 3 minutes; it's now just a hair below the "full" line.
And here's my tip for getting an accurate reading while holding the bike upright off the side-stand: while holding the bike steady with one hand on the handlebar, place the fingernail of your other hand at the oil level in the sight glass (careful though, the case might be hot), then lower the bike back onto the side-stand while keeping your finger on the sight glass. Once the bike is back stable on the stand you can take a close look at exactly where your oil level was in the glass.
Even though it's hard to see while holding the bike up, I think the sight glass is much easier to get an quick, accurate reading from than a dipstick.
