Spark Plugs?

Do you guys change your plugs every year? for only 9 bucks I was thinking of changing them even though they only have 2,000 miles on them.

I don't. I probably run mine too long. I just remember asking my dealer about a tune up on my '90 Softail Custom shortly after I bought it, and his advice was 'If it ain't broke, don't fix it'. I've used that philosophy all along. I think I only changed my plugs once in 23,000 miles on my '97 Heritage Springer.

Probably not necessary. Manual says to inspect them every 5k and change them every 20k. BTW, you can get excellent plugs for $1.50-2.00 each by buying something without "Harley-Davidson" stenciled on them. HD plugs are made by Champion, I hear. I use Autolite 4163, which are one-step colder than normal.

RE: Spark Plugs?

the autolites (4164 is normal, see iclicks post) have better reviews than the champion plugs. on my sportster, i used to change the plugs at every oil change (hey, it was only 3.00, gotta love fresh plugs) but on the road king i'm still running the original plugs and i have over 14k on the clock. i've checked them a couple of times, but they still look great. i probably will change them in the spring anyway.

that has happened. i have heard of people getting a hold of a bad plug or two..... never destroy/throw away your old plugs till you are sure that the new ones are good.
