Time to change my spark plugs again and was wondering if I should just go stock again or try something else. What plug are you running?
Nearly word for word, had nearly the same experience.I just did my 7500 mile service and changed the plugs. I wasn't going to, the bike is running purrrr-fect. The plugs were chocolate brown, no apparent wear, gap still at .28. I just replaced with the stock NGK cr9e's at $4 a whack. I may go with the iridium next time, I think they are about twice the price as stock.
Thanks for the info....Nevermind guys, found them. Here it is for anybody else who wants to know. I accidently copied too much info. But they are not cheap.
GSXR1300 Hayabusa 1999-2003 CR9EIX Iridium 14.28
but then again I did a search on Ebay 4 for 25 bucks......
