07-09 600RR Spark Plugs....

[JRide]

So, after my lowside my bike takes a few more cranks to fire up. I'm pretty sure I fouled a spark plug or two. I went to Manchester Honda thinking they may be a little more expensive but I'm willing to pay a dollar or two more per plug to have them instantly....I'd get charged shipping anyway....yeah......they wanted $26 per plug!!!

I came home and started searching around and came across this site:

I just paid $51 and change for 4 of them including shipping. Half the price of what Manchester Honda wanted. Not sure what the other bikes run or the 05-06 CBR's but I just wanted to give you guys a heads up.

John, that's retarded money for stinkin spark plugs. I'll see if I can cross reference it to something more affordable.

$10 a plug is still retarded money?

FWIW; I don't recall ever paying more than $8 per and that was plugs for a 5 series BMW.

Hmmm....I searched a couple of places but this was the cheapest I found. Noel, let me know what you find.

It really depends on the bike and the type of plugs it requires. For some reason Honda plugs seem to cost more then a lot of other bikes. The ones that were for my RC51 were a ton of money while the ones for my R6 are the same price as any normal plug

Yeah, my bike uses "Laser Platinum Iridium" plugs.

I've always gone with iridium IX plugs which run about $10.50 a plug

Be thankful you don't have HRC plugs...

[butcher bergs]

I stocked up on certain plugs a while back.....maybe things are more expensive than I recall.

The BMW I mentioned used some kind of silver plugs....again, this is going back some years.

If they were iridiums and not damaged should have just cleaned them

spray with carb or brake cleaner

If still looks funky then tooth brush with abarasive cleaner (comet etc.)

rinse GAP and ride

Thanks for the heads up on the plugs.. My 05 has 7k on it. when are the plugs supposed to be changed on a bike? my car's go for 50 - 60k but i have no idea about this shit. maybe I should be changing those more often? I use the Iridium 4's from Bosch

Thought you werent supposed to gap iridiums? Cant that damage the electrode? Id imagine it would be the same for hitting with a cleaner like comet.

You might be due. It depends on how you ride. Some bikes respond better to newer plugs then others. My RC51 would liven up a lot with the change after about 4k

Looks like another thing to add to the long list of Winter upgrades and maintenance

The point (pun intended) is the iridium wire electrode is hard and high temperature enough so that it can be a thin wire and still hold up.

Electric fields like to leap to and from points where the flux is concentrated. So the thin wire point creates a consistent hot spark from a known position requiring less power to do so.

If the insulator is clean so electricity can not track down the surface and the gap to the electrode is within specs your there.

I am sure Iridiums in water cooled motorcycles should last 10's of thousands of miles like 30K.

However both the spark plug cap, cap resistor and spark wires are now probably a bigger wear parts than the plugs themselves. Check the resistance on your caps and wires and you may be surprised.
