With some of the recent talk of having to get the bike on the center stand for checking the oil level and using mirrors, strange body contorsions, or getting the significant other to look, I never thought to share this tip which might make things a little easier for some.
Get the bike on level ground and up on the center stand, check the oil.
Get the level where you're happy with it.
Now, take the bike off the centerstand, and put it on the sidestand where you plan on usually checking the oil.
Take a good look at the sightglass again and see where it is. If it's now way above the sightglass, well, I just made you read through this for nothing
But, if you can see the level now, just use that as a reference point the next time ya check it.
No more having to be on the centerstand !!
Wouldn't hurt to mark that level in some way if ya need to. Just a small dot of paint should do the trick.
Well, that's my tip for now.
