PanAm Clean-Funnel
PanAm Clean-Funnel
A good funnel is a must have in any workshop when it’s time for an oil change or a refill. The annoying part of these jobs was to stow away the oil dripping funnel into a dark corner where you would find it a few months later contaminated inside-outside with dust, bugs and other debris. The PanAm funnel puts an end to this problem because it features screw-on caps at the top and bottom which can be removed for action and which keep the inside of your funnel perfectly clean during storage. The flexible spout makes it more versatile as it allows to direct the funnel tip in tight spots.

Fork Oil

Fork oils for hydraulic telescopic forks on Harley-Davidson motorcycles are classically monograde oils. Forks simply do not reach the operating temperatures that would make a multigrade oil necessary. The very first hydraulic forks on Harleys were even filled with SAE 50 engine oil. Since then, however, oil technology has made enormous progress and fork oils are specially adapted to their intended use.

How often do you have to change fork oil? Which fork oil should I use for my Harley?

Generally not nearly as often as engine oil, but the intervals should still be observed. Fork oil also ages. The correct change intervals can be found in the workshop manuals. You can also find an overview of how much fork oil and which type you need for your model in the manuals or in our Tech Tips.
