Cutting open the oil filter is a good idea. You can check the particles with a magnet, with an integral transmission and a wet clutch it's always possible to get the odd flake or two. If you are really concerned it doesn't cost that much to have an oil analysis done which will tell you how much and what type of metal is present in the oil.

Some metal in the oil or filter isn't as threatening as it would be in a car engine. It's most likely from the transmission or clutch. A filter analysis would go a long way to determine if it's bearing material or steel. Basically if there are no other symptoms there's not much else you can do about it anyway. Keep an eye on it, maybe change the oil and filter after 1000 more miles and take a look at the filter again. If it's still showing metal then there might be a problem. It's entirely possible that some metal from the transmission, clutch, starter, primary chain, etc. was buried in some gunk and a change of oil brand or some such loosened it up and it got into circulation.
