Re: Question on NGK Iridium Spark Plugs
Thanks folks for the responses. I have always used NGK and changed them at 20,000km. I am surprised that all of you seem to suggest that you can use them even longer. I think that changing them at 20,000km was initiated by the dealer during the schedule service. I took their word for it. Part of the problem is that I am not as schooled as most of you on the technical and mechanical matters.
To answer your question, my friend recommended iridium plugs, but now I remember he rides a superbike which is a different bike in character. I am happy to stay with the standard NGK plugs, especially now that I have discovered that I can keep them longer.
While we are still on this topic I have two more questions:
a) Is the changing of spark plugs a highly specialized field that can be done only be a qualified mechanic say at Yamaha dealership or other? Suppose the answer is no, it then means that I as an amateur with some instructions from a qualified mechanic can change them. The reason I am asking is that every time I take my bike into the dealership, they claim they need an hour to change plugs and of course charge accordingly. I am think of doing it myself with some help here.
b) Where are the plugs located and what process should I follow to the take them out and to install them? I will appreciate any input on this matter.
I will keep you posted.
