Actually, these filters work pretty good. As stated before....this is the same setup as on the CB350s. Any dirt or depris in the oil will be collected on the inside....sides of the filter housing. Of the motors I have rebuilt.....I have never seen enough in the filter to be an issue....that you should pull the filter on a reqular basis to clean. But....should you want to pull it and give it a good cleaning, you will need the special Honda oil filter nut removal tool.
