Help! I have replaced the rubber seal on the tac drive on my 71 xs1-b, and it continues to leak oil. It leaks less than before, but still not completely fixed. This is down on the bottom of the cable where it enters the engine case. Any suggestions? What are the odds of a bad seal?
 
Typically the shaft of the tach drive is rusty/worn the seal doesn't really stop the oil.
