quick question...took out my spark plugs to inspect and are perfectly fine...should i still run them for the next season??? my bike only has 2500 miles on it...and should i get hotter or colder ones, no discolor of the spark plugs(white or burnt)????
inspect around 4,000 replace at 7500. if they looks good I would leave them alone personally but if you do alot of racing most would say replace every season probably.

Go to Advance and pick up some NGK Iridiums they will give you a better spark...should be a CR9EIX or whatever number you have on the plug in your bike right now just add IX to the end of the number....runs a little cleaner...should be around $7.99 a piece
i was looking at those plug too.. looks pretty sick.. dont know if you will feel a difference... maybe there is some.. but very small i guess... i already did my plug change at 8000 with race filter...NGK.. they seem to work pretty good..
what color where the plugs when you took them out? if they are the color of a paper bag put the same cr9e back in the bike if the plug was wet and black put a cr8e in the bike. you want the plug to be the color of a paper bag and not wet or black! but since you have already taken them out go ahead and replace them. and for the iridium plugs it is a waste of money
YOu have my attn - What is a cre8? I just bought a 06 gsxr 1000 and the plugs are black at 7500 miles. ngk cr9e is what is in them now. Whats the difference?
CR8E is a hotter version of the CR9E std plug. If your plugs are black and wet then change to the CR8E. However if you've just bought the bike then id suggest you stay with the CR9E until you see what they are like from YOUR riding.
CR8 is a hotter plug. Same design, just runs one level hotter, which should burn better if you are running rich.
I blackish plug would indicate a rich mixture, or oil going up there. A hotter plug can cure some of that.
Cons: You got to watch your detonation. You may have to switch to higher octane gas as regular may explodes before its time due to the heat.
Also make sure that is the cause. For example, you may have a dirty air filter not allowing enough air. Consequently more fuel than air goes in and the plugs foul or get black.

Re: Spark plug change?!?!?
I don't put antisieze on my plugs, never have and never had a problem but most recommend it so you don't strip the threads in the block.
To the OP if your plugs are fine why spend the extra money? Service and Owner's manuals say to replace every 7,500 or so miles. You can replace if you want at 2,500 to but there's really no point if the bike is still running good and they don't have any abnormal wear.
how difficult is it to change the plugs yourself?? my plug change is pending to instead of taking it to the dealer i was planning to do it myself, i usually prefer woking on my bike myself...beeing a professional aircraft mech it usualy turns out fine...
so what u think?...is it ok to DIY?? also do we have the plug sized wrench in the tool kit?
along with the plugs.....Who puts antisieze on the threads and why?
