Some time ago I purchased the oil filter adaptor from CNW so that I can fit a more common oil filter to my MK111. My Norton will wet sump after a couple of days sitting - not that I consider this to be a problem that some people do.
Some of the filters Matt recommends are not available in AUS but I found an equivalent to the FRAM PH3614 he recommends which is a RYCO Z87A. This filter has an anti-drain valve built into the filter. It is also slightly longer than the original, but more capacity has to be a good thing. After an oil change to Penrite 50W - It's bloody hot over here at the moment - I have let the bike sit for 4 days and low and behold, no wet sumping !
Time will tell if it remains that way, but if it does, this may be a better and much safer solution than some of the ideas I have read here.
I'm not sure if these filters are available everywhere, but it may be worth a try.
