Plugs can be cleaned & gaped, but if their anything like my F3, why go to all that trouble & not put in a new set. It all depends on how old & what condition their in.
Check your plugs against the colour chart in your manual or here: http://www.ngksparkplugs.com/tech_su...qs/faqread.asp
I use NGK or Nippon Denso.

Have 'em in the bike and the cars ........just last way longer
Spark just the same as all the others. They cost more so
not sure what the saving's are.........I put em in vehicles
where the plugs are less than easy to get at regularily.
Cane ain't bad but the volvo and the explorer suck for
changing plugs.

Agreed. Iridium last longer. That's where the economy comes from. Same fire just for longer = less maintenance = less cost. I must admit that I just use standard NGK's. I find that Nippon Denso don't last as long. Bosch are good in an old oily motor but haven't had that problem for many years.

Fire is fire. You either have it or you don't
Plus, with the electrical system being subpar on motorcycles, many of them need the Iridiums and are designed around them. Placing in any other plug will work, but a loss in hp is almost guaranteed. Not to mention the risk of fouling out plugs.
Now, if your bike wasnt designed to run on Iridiums, it may not really matter if you run them or not. But if your bike was designed to run on Iridiums, it will not run as well on a standard plug.
Its foolish to think that with the main components of air, fuel, compression and spark, that one of the four can be lacking and still make the same power.

Well put. I don't know anything about the later models but my 87 was not designed for iridium plugs. Also the compression is quite low so I would be surprised if there was any noticeable power increase for using them. The only accurate way would be to run a test on a dyno but I'm not going there. It's interesting to note that when I was a teen I rode a 250 two stroke & the Nippon Denso plugs always seemed to give more power but with a short life. But then it could also be like the exhaust. Put on a loud exhaust & it goes faster because it sounds faster but is slower in reality???
