Well about to round out my fourth season on the 14r. Bike has been great but at just under 20k I think its time for some service. Thinking I am gonna change the plugs, coolant and have the steering head cleaned and repacked with grease and have the brake fluid changed. Anyone know the part number for the Iridium plugs for the Gen II and any recommendations for quality coolant(was thinking of using Honda pre-mixed). Thanks
