Sprint P08-F185 Filter 3000 mile report.
So today I cleaned the Sprint P08-F185 filter after 3000 miles on Nevada/Calif roads. Our roads have been covered with sand and Nevada is a dusty dirty place anyway. The sand gets ground up into a fine silt and air filters take a beating. So opening up the filter box there is the normal oil from the crankcase and the dirty side of the filter is a mess, the dirt is pretty caked on and there was more than I expected. Took off the filter and the clean side was stunningly clean. I could not detect the slightest bit of dirt/grit with clean hands. I wiped with a white paper towel and it was the color of the oil. No detectable dirt.
I couldn't be happier with that filter.
I was getting a bit of oil build up, then realized the drain hole for any oil has a sealed catch plug that had filled. The bike has 14,000 miles so that would be pretty normal.
Any question about that filter in my mind has totally been answered.
