daman, I am talking about the "OIL" filters, I was just curious how many people ran them and if some even have even heard about them?
I am not too concerned about the efficiency numbers as I am pretty sure they are quality oil filters, especially after what I was told about them by a very reputable motorcycle shop. (maybe naive on my part?)
I also believe if Yamaha says it is ok to change their oil filters every other oil change or longer then I will be perfectly fine using this filter and changing it "every" time I change the oil, which will more than likely be at least twice a year?
Imo, they are a quality filter, they are well built, have anti-drain back diaphrams and have been around and used by various off-roading enthusiests for years.
