Hi folks, what do you make of this. ok they were fitted 2 years ago, 7k miles. I know i replaced the plug caps correctly. my Question is whats the point in fitting iridium (supposedly longer life) when the rest of the plug is made from recycled baked bean cans

It might be worth you clearing the drain holes from the plug wells. It looks like they are blocked and your plugs have been sitting in an inch or two of water.

Replaced my plugs recently. They had only been fitted last August and were pretty corroded. The drain hole was totally clear.

Hi , found the drain hole,(thanks) ran a ss wire full length and checked each plug port with a mirror/ light. It was perfectly clear so standing by my previous rant...for the mo

If you running very slightly rich it might be worth checking you air filter is clean, cos, a grubby filter can cause that. Certainly check it before tweaking carbs.

I replaced my NGK Iridium plugs after 24k and they didn't look anything near as corroded as those. The web is full of posts about knock-off NGK plugs which is why I only buy from reputable stores and not an eBay merchant.

Hi Tommyardin, its a K&N air filter fitted same time as iridium plugs, it was totally clean but soaking (i mean dripping with fuel) when i checked it a few weeks ago and from what ive gathered so far is I think I have a carb issue. cheers

Hi PieEater now I Know why folks call em Halfrauds cos thats where I bought the plugs. Cheers

If you haven't checked them in the last two years, I wonder what state all the other metal bits you don't look at are in? The drain holes may be clear now, but the damage in the pictures looks pretty much exactly what I would expect if the plugs were left sitting in a puddle of salty water on a regular basis.

Service manual calls for "Check condition" and "Clean and regap" every 10,000km, looks like you have some serious cleaning to do.

They could also be counterfeit NGK with piss poor metal from good ole China?

So I let the plug service run on for 800 miles what a sin.

the bike is serviced by the book at or around the end of summer. Never used in winter or on the beach.

Three season,
I just noticed there does not appear to be any crush seal/washers on any of the plugs in your picture at the beginning of this post.
If they came off as you removed the plugs I would be doubtful that they are genuine plugs in the first place, or did you take them off?
I only check my plugs at the beginning of each year, about 2,500 miles. they are usually slate grey in colour and dry, I wipe a little cooper slip on the threads when they go back in, and I only change the plugs every 4 years or 10,000 what ever comes first.

Hi Tommyardin the crush washers are there, i double checked, just cant see them for crud. I have always serviced/ replaced plugs no matter which vehicle by the manual but it seems I expected too much from iridium plugs. Cheers

If the plugs are genuine then you would have had the same issue with standard plugs, the fact that they have iridium tips has nothing to do with the external construction. As I said I replaced my Iridium plugs after 26k and to be honest they didn't need replacing, they certainly didn't look anything like yours. I don't think your experience is typical of iridium plugs or plugs in general. You could send your photo to NGK to see if they have any comments.

The standard plugs I removed 7000 mls ago to replace with iridium were pretty good nic so I can only presume they were part of a bad batch like many mass produced stuff manufactured these days. I would like to reiterate that the drain holes were spotless as with the plug ports and my bike is serviced and cleaned to a high standard. Cheeri

Theres an article on spotting fake plugs
http://www.ngk-sparkplugs.jp/english/techinfo/fake/

They look worse than the iridium I took out of my 600 after it had been sat unused for 4 years outside
NGK not normally that bad , maybe as you say bad batch ?
