change spark plugs

Just changed plugs in my left over 2013 SilverWing---used tools I carry on board--just to make sure I am carrying the right stuff.

It appears to me good service life of spark plugs in SilverWing, which is 40-50,000 miles, sure they would have made it to near 50,000---but I had time, wanted a look and had 2 new plugs on hand.

Total time under 30 minutes, including clean up and putting tools away.AND cleaning Never Seize off my hands and bike.

My first SilverWing was traded at near 50,000 miles, running fine on the original plugs...never bothered to look.

I did drop one small self tapping screw---rather than chase it I just took another from my junk stock.

Referred to shop manual before I got stared---to make sure I was doing it the simple way.

I did mine a month ago and was pleasantly surprised at how easy it was.

 fyi used Autolite XS4303DP Xtreme Sport Iridium Powersports Spark Plugs

Why not the plug Honda recomends? Hard to improve on their recommendation.

Honda dealer sugested those.

dealer probably doesn't really ride....and he makes more money on his recommendation?

Using lead free gasoline with electronic ignition spark plugs last nearly forever. I had 100,000+ miles on the plugs on my GL1500. I changed them when replacing the timing belts, just because. Not because they really needed it. I got 160,000 miles on the original plugs in a car I owned. Sold it with those still working fine.
If an engine starts quickly, idles smoothly, takes rapid acceleration smoothly and fuel mileage doesn't drop I can't see any reason to change spark plugs.

I looked at the plugs this week, and refitted the existing ones back. Access very good.

The removal of lead from gasoline nearly eliminated built up on spark plug electrodes. The advent of electronic ignition which not only made ignition timing far more accurate and consistent also creates a higher ignition voltage. These advances mean a plug can last nearly forever as long as the engine isn't burning oil.

Changed mine at 8K, they looked fine but I had the 5 year warranty from Honda so followed their recommendation. Installed NGK Iridium plugs, easy job and I will probably never have to check them again!!!
