ourian Posted February 23, 2015 Report Share Posted February 23, 2015 (edited) Are you sure it gives the quantity by weight? Measuring oil in grams just doesn't seem right Anyway density of oil is somewhere between 850kg/m3 to 900kg/m3 500g at 900kg/m3 1litre would weight 900g so 500g would be 555ml (edit) Density of ATF oil is approx 865kg/m3 this would equate to 500g being 578ml Edited February 23, 2015 by ourian Quote Link to comment Share on other sites More sharing options...
fitz_the_viking Posted February 23, 2015 Author Report Share Posted February 23, 2015 (edited) it doesnt make sense to me to have it by weight, like you have shown the volume changes with different oils. but seeing as you know quite a bit about oil i will be using an 80 weight oil. so 550mls seems like a sensible place to start.

ourian Posted February 23, 2015 Report Share Posted February 23, 2015 If you google the density of the oil you're using and measure the temperature of the oil, just to make it more confusing, oil's density changes with temperature, which is why they've probably specified the amount of oil by weight, i.e. it's volume will change with temp but it's mass will stay the same. But I agree 550mls seems about right at 20 degrees celsius Quote Link to comment Share on other sites More sharing options...
dan williams Posted February 24, 2015 Report Share Posted February 24, 2015 Just fill it until you start to see oil in the sight glass on the side of the case with the bike level. Quote Link to comment Share on other sites More sharing options...
