Fresh Plugs

[Dogsled]

I decided to change my spark plugs. It takes a long time for my bike to warm up where I can get on and ride. I pulled the plugs and they were clean like new. I had the plugs so I put them in. I rememeber a long time ago we'd change plugs and looks didn't have anything to do with it. Clean plugs mean't you just had a solid, tight running engine. What's the general impression of leaving plugs in for 6 or 7 years....should I get better performance, is there an internal plug life that cheat your performance and gas mileage? I used good, recomended NGK's

Spark plugs are things, like rocks and concrete. After a while of being exposed, they may look a bit tatty, but the rocks and concrete will still perform. The same with spark plugs. As long as they perform to specification, then they should be alright. Wear can occur at the electrode end, where the spark is produced, as it will eventually will wear the metal away - just like water will to rocks and concrete.

If the plugs look alright, work alright, and dont have any cracks in the porcelain, then they should be alright. They are not like hamburger meat, and will not go off with age, but treat them right, keep them correctly gapped, keep them clean, and they could last longer than your 6 or 7 years.

No need to waste money, it would be like changing your oil at 1 000 rather than the 8 000 miles / 12 000 Km that is contained in the service books. Of course, you may need to change your oil more often if you are working your GW in dirty conditions, or using it for mail delivery with lots of stops and starts, but you should be aware that overservicing is not a good thing.

Well I bought the plugs and had them in my tool box.....BTW, thanks for your input. The pugs looked real good and hopefully thats a sign my bike got alot of miles left. I didn't have a miss or any 'bad plug' indications....but like I said they were there, so.................
I was hoping the older plugs may be causing the or at least help the long warm up time (it didn't). I know it's not electronic ignition and jump on and go and like the fact it's getting older and more classic. My last bike was a 59 Harley and had kickstart only....can't get much more classic than that Everything performs well so with the new plugs in, i'll just keep riding and waiting til it warms up.....because when it does IT RUNS!!!!!

My 1500 always required a little choke to start in the morning regardless of temperature outside. But a 2 minute warmup and it was ready to go. It had original plugs in it, so I changed to Iridium's. It may have helped some with fuel economy, but the morning start up still persists. BTW: after warm up, the starter doesn't even turn the engine over once to start.
