I just read a post on changing the oil but it still didn't directly state my answer. For Checking not Changing do you check the dipstick with it on side stand or center stand?
Center-stand after warmed up for a couple and then sitting for a couple (for both actually)..
*Just a side note, once you get the level where you like it in the crosshatch area, I check it another way which is much simpler.
I park the bike in the exact same spot in the garage. Once the engine is cold (all the oil drained down), I re-check and make note
where it is WHILE ON THE SIDE STAND. I don't check it often as it doesn't burn a drop but its nice to have the option..
From page 7-12 of the S2 owners manual; (lower left corner)
"Remove the engine oil dipstick and wipe it clean, insert it back into the hole (without screwing it in), and then remove it again to check the oil level".
**DO NOT SCREW THE STICK IN WHEN CHECKING.. That will lead to a lower, specified oil level...**.
Glad you posted that. I always wondered: "Do I thread the dipstick in first before reading or not?" Next time, I won't thread it in (but have for last 40K miles). Once I overfilled it and oil seeped out of the right side cover. Sucked out some oil with syringe and oil seeping stopped immediately.
The little bit it'd be over isn't much but if your high revving the engine often, with a high level, I suspect you'll possibly get a bit more crankcase blow back into the air filter filter area (where the crankcase vents to)...
And as you've posted, the higher oil level did cause a minor in your case, just that little bit..
Extra oil on a paper filter isn't the best thing either...:thumbup:
