spark plug

  1. Maintenance and Modifications
    Hi, I'm new to these Boxer engines (been all Japanese in line 4's up until now) and when changing a plug the other day I noticed oil in the ignition coil chamber. Any chance it's normal for these engines to discharge a small bit of oil here, or am I in trouble? It's an '06 R1200GS. Thanks.

    Has anyone tried using the new E3 Spark Plugs in their bike? Did you put them in the primary position or secondary too? Did you notice any difference in performance? Did you see an increase in gas mileage?
