Had the fuel tank and radiator removed for maintenance (valves) and decided to check the spark-plugs while i have access to them.

Suzuki, in owner's manual, recommend to replace them at 12,000km. I think it's a mistake and they forgot to update this when they switched from regular spark-plug to iridiums. On my car i changed them to 175,000 km, so i figured that on the bike they should be good to half of this considering the motor RPM on the bike is twice.

I have now 46,000 km and think i could have let them another year, (25,000 more km) but i changed them now because i'm not sure that next year i will remove the tank and check the valves, because the gap seem stabilized now. Only 2 valves were different from last year (at 24,000 km) and the changes were only 0,001".

So for those who wonder what they look like at 46,000km (near 30,000m) i took photo of it, with a new one.

Interesting. Thanks.

Other than color I see no difference.

There is a little metal worn off the ground electrode but that won't really affect performance. I'm probably going to be too old to ride before mine need replacement.

Good to know. I've been looking to see if I need to replace my plugs since I'm searching to why my gas mileage has dropped drastically.

You've probably checked the usual suspects but I had some quite stiff front wheel bearings that were causing my gas mileage to drop. Once I changed those it was back to normal. Might be worth a look.

Interesting. Can you tell at what mileage you changed the bearings?

This was on my Versys and I'm guessing those bearings had about 20k miles on them (I don't keep great records and I changed the front bearings a couple of times over the time I owned the bike). I think of bearings as consumables: silty water crossings and the pounding they take from rough roads can wear them out quicker than you would think.
