Paul, >From past discussions here, the consensus is that K&N is too efficient for Nighthawks, allowing more air volume to flow, therefore upsetting the already too lean OEM fuel-to-air ratio.
That would require fiddly adjustment/modification of the carbs to richen the mixture. More air = need for more fuel, in other words. I recall we had one member experimenting with inserting a cut down yogurt cup or some such into the filter, trying to reduce the air flow. The UNI filter, on the other hand, is not as efficient, or at least not enuf to require carb adjustment. Not on the Nighthawks, anyway. Your Goldwing mileage may vary. Both filters are similar in design, except that the UNI uses the foam type filtering medium and a plastic cage type structure. K&N is metal and wire and appears to be more substantial construction. Some would say overbuilt. That, and it's national name brand advertising budget is probably why it's more expensive. Both are reusable and require periodic cleaning and recoating with a proprietary "oil," -- a sticky, messy stuff with a consistency similar to honey. I have the UNI and it works fine. It's half to a third cheaper (I paid about $26, I think) and touted to have life-of-the-vehicle service life. If I had it to do again, I would spring for the spray type oil. Less mess than saturating the filter by spreading the goop around and working it into the foam with your finger. -- You received this message because you are subscribed to the Google Groups "Nighthawk Motorcycle Lovers!" group.
