That's funny. I find the 504/505 points system needs very little maintenance. The main time I need to adjust the points is 1000km or so after fitting the points because the rubbing block "wears in" at first. After that I go tens of thousands of kms without touching them, and up to 100,000km or more without replacing them.frogs4ever:
determined to upgrade from the standard points system which requires constant maintenance .
