I changed out to NGK Iridiums after I looked down and saw my OEM plugs rusting out one day. Never had a problem and last time I checked 'em they were beautiful.

I run only Champion plugs on everything that comes into my shop. It's not a money thing in so far as Champion makes the plugs for Harley and only single seals them where as the regular Champion RN12YC is double sealed.

I am running stock. Is there a real reason to change?

other than "fix it til you break it".?

Really there is no real reason to change from stock. Personally I run Champions, because I can get them at a deal. Same as oe. I look at it as there are many manufactures for plugs, just like diffrent exhasut manufactures. There is no "right" answer or brand. Just prefrence.
