Oil level

[mr8ball]

I am always at 3.75 as well with filter

4 quarts here as well, just easier that way.

If your holding the bike up by hand it takes only slight movement to change level in site glass. I gage by amount from the bottles.

I just look at my last quart going in and leave a quarter in it. Fills to the top line every time.
I don't overthink it.

Same here, never an issue.

Why did suzuki says it only require 3.5 quart when it require much more than that.

Some models are different, european, US, California ( the other US ). So do what zuki states in the manual for your model.

i'm with six pack....3.75 w/ a filter change = right at the F mark on the sight glass...remember to check with the bike with both tires on the ground, off the kickstand, straight up

easy peazy

Yes, i checked the oil with both tires on the ground and with my bike upright on a flat surface. I think it could be because i parked my bike on a slight incline slope when draining the oil, thats why i got more oil to drain from the bike. Could it be possible????

Four quarts with filter, never have a problem.
