After all of those years trying to rig something up using turkey basters, measuring cups, funnels and sections of hose to get the same amount of oil in each fork. Finally a simple, economical solution. No more calculating how much you spilled and wondering if you got the same amount of oil in each fork. Easy, Fast and Accurate!
I purchased this with the intent of accurately filling both struts in my '83' FXRS. First, its fill quantity is measured in CC's which I then had to translate to ounces. Then it would not draw the oil out of the bottle very well, seemed weak. I gave up on it and got a accurate lab bottle measured in ounces and just poured the required amount in each strut. That worked. I may have miss judged exactly what this thing does, but did not work well for me. Just my 2cents.
