It's nice though to see that Pro Oiler evolved with the GPS unit and the nozzle setup looks great as well, I wonder about the rest of the setup (pump, sealing of the computing unit / junction box) etc? Where did you leave the oil container, do you have a picture of that?
I've used Pro-Oilers for the last 10 years or so on four different bikes. They have evolved indeed.
I can tell by the installation manual. It used to be quite a few pages, but with the GPS unit, the manual is only one page, indeed plug an play.
The unit comes allready set for your type of bike so no need to adjust anything.
Pro-Oiler recommends fresh, clean engine oil to be used.
I never had trouble with moisture entering the unit, but I do not use high pressure jet cleaners directly on the unit. (Brammo warns against using high pressure cleaners too)
I used other Chain oilers too, but they were either manually operated (wear increases inbetween activations) or single setting gravity fed Oilers, that need constant adjustments and do not work in the winter.
Riding all year I wonder how the Empulse will perform in the winter.
