I ended up having enough in my Uni can to do the filter this time around. I bought a can of the PJ-1 foam filter oil that was recommended.
In hindsight, it would be nice to have either all Uni or all K&N filters in my vehicles, not both. Of course, K&N didn't make a filter at the time I bought the bike.
Anyone want to trade a Uni for a K&N? <g>
