Lately we have been using the NGK BPR6EIX Iridium which gives a little better throttle response and lasts quite a bit longer. For sustained high RPM's you could go a step colder and try the BPR7ES or BPR7EIX. Remember, with the Yamaha, good plug color with low CHT's is the way to go.Wed, 20 Apr 2005 12:20:06 GMTBurris Tech Info
