what you see behind the wiper

[pdedse]

Dear experienced CB owner with a pretty wiper in the oil check window ... I guess you know what I mean. Could one of you please try and explain the following observations :

- oil & filter change, carefully filled up, but after test ride I notice that there is a little too much oil in the engine,
- on the main stand, oil level is a tenth of an inch above the upper level line, still a little air visible in the window,
- an hour later I open the oil filter a little, a little oil runs out ( as expected ) and I screw the filter back on,
- next I check the window, and guess what, the whole window is filled with oil, no air bubble visible no more,
- next I run the engine for a minute, wait 5 minutes, to check the window again: level is right at the upper mark.

I am not a firm believer in daemons or wizards, and the final result is just what I wanted. BUT: how can the level go up in between ? The bike wasn't moved one inch during the procedure.

Yeah, but what time of the day was it? Earth rotation, gravity...it's a well-known fact.

EDIT: you also might consider changing that wiper blade. They tend to deteriorate with sun exposure.
