New spark plugs for my NC after 48000km.
Put the old ones back and go another 48000 km. The Honda recommended change interval on these is too short, IMO. Even NGK says they'll go a lot longer.

New spark plugs for my NC after 48000km.
So they can go more than 48000km?
So they can go more than 48000km?
wow that's amazing I thought they topped out at 60k, to last over 100k makes charging $40 or more per plug allot more justifiedI have no problem believing these plugs. I do think the original plugs can do around 100,000 miles. I have somewhat simular plugs in my auto that do not even require a change to 98,000 miles. My daughter put 130,000 miles on her auto plugs.
I used some temp antisieze and the bike seems just as it did before.
Unfortunately it's already done. I was quite careful and used as little as I thought it needed. Thanks for the link though.
8. With the plug washers attached, thread the spark plugs in by hand to prevent cross-threading.
9. Tighten each spark plug:
*If the old plug is good:
-1/8 turn after it seats
*If installing a new plug, tighten it twice to prevent loosening:
a) First, tighten the plug:
NGK: 2/3 turn after it seats.
b) Then loosen the plug.
c) Next, tighten the plug again:
1/8 turn after it seats.
...so the whole spark plug thing is kind of a non issue.
It is a non-issue regarding cost whether you keep the bike or not. Here is a discounted source of the specified plug...
NGK Spark Plugs IFR6G-11K, NGK Laser Iridium Spark Plugs | NGK Spark Plugs
If you changed them every 30,000 miles (crazy, I know) then your cost is nine one-hundredths of a cent per mile. You could cut the cost in half (still using the specified plugs) by running them until the electrodes showed wear as described in the service manual.
As far as whether the specified plug is "required", we have ample proof that it is not. The "G" and "K" feature descriptors identify special attributes of the plug that we do not have the information to identify. The theories about this range from "small differences" that either do or don't matter to assertions that they are the same as plugs with similar part numbers and it is a devious plot by Honda/NGK to part us from our money. I don't see a Japanese company pulling this tactic. I wouldn't put it past the Germans though. Regardless, from a practical (non-ethical) perspective, it doesn't seem to generate enough money to be worth the potential damage to an honorable reputation.
So, my decision is to blow the 9/100 of a cent per mile and give my baby the factory diet at the specified feeding intervals..
You just save me 60 dollar in spark plugs, greatly appreciate it, ThanksThis spark plug thing Honda has going really for some reason just got to me. I am sorry, but I will not get ripped off for $30 for a spark plug.
Even the auto parts stores can not get the IFR6G-11K plug. This plug is listed by NGK as a dealer order plug only. So no one but a Honda dealership can obtain this plug. Honda is NGK biggest customer, and they have a monopoly on this plug. If you are on the road, and this plug goes south on you, you just can not get another plug. Very few Honda dealerships keep this plug in stock because of the price, and the dealership has to buy a full case of these plugs.
I have a friend who gave me some big help here, and for obvious reasons I can not mention their name. The good news is you can get another NGK plug that will do the same job, and all is exact with heat range and length. This plug is an NGK and can be bought at any auto parts store for less than $2.50. All measurement and heat ranges are exact, and it is a NGK plug. The difference is the material used in the Spark Plug Diode, and Honda's monopoly. Honda states in the owners manual to change the spark plug at 32,000 miles with the Iridium diode spark plug. NGK states change to this other spark plug at 32,000 miles with the copper/nickel diode spark plug. Yes, I can purchase the BKR6E-11 NGK plug everywhere, even on the road at any parts house. NGK part number 2756. So, 2X30 = $60 /or/ 2X2.5 = $5. If nothing else write the number BKR6E-11 and NGK part number 2756 in your owners manual, you could need it someday when on the road. Guess what spark plug I now run in my bike..........
