Replaced plugs at 36K miles
I did not replace the plugs at 18K, I waited until i had the 36k service done. The plugs look great, I was surprised, even the mechanic said they looked good.
So it worked for me and I saved some money.
I ride fast but don't push the bike really hard. never got more then 6k out of a set of tires and I keep the bike in "ROAD MODE" and don't really tach it way up very often.
The reason I waited was at $25 a plug I really think they should last longer then 18k miles.
When I bought the bike in for the 18K service the gas mileage was great and it idled fine and was running really smooth, when the plugs are going bad your fuel mileage starts to suffer and it will start to run ruff. I bought a set of plugs and was planning on changing them when I started to see a drop in performance but that never happened. I was getting 41mpg when I brought it in. That's what I always get.
Just thought id share.
My K16 is approximately my 50th motorcycle.
