I have a 2014 Yamaha ybr, I recently got someone to do an oil change for me and instead of putting a 1L in they have done it on the side stand and put 2 litres in. I rode like it for 2 weeks before I’ve checked it this morning and the dipstick was all the way to the top, it hasn’t actually done anything to the bike but my question is will it, there are no leaks of any sign of engine damage whatsoever but I am just weary about it all.
