2009 GSXR SPARK PLUG ISSUES!

1565 Views 9 Replies 4 Participants Last post by  TwistedMister
Hello so my 2009 GSXR 750 had a ruff idle 2 weeks ago so I bought NGK Laser Iridium Spark Plugs and the ruff idle went away and ran PERFECT! now today the ruff idle came back so I took out the spark plugs again and noticed all 4 plugs were Loose and burnt. I took it to advanced auto parts and they told me I didn't tighten them up properly. So this time I installed new once and tightened them properly. It ran good for 1 hour and once again it came back.... please help 馃檹

are those the newer iridium laser?

the burn doesn't look horrible but why are they wet around the ground electrode and nose?

they very well may be the wrong plugs if they are burning odd like that, you want the ground electrode to look tan but like a flat tan and consistent in color or shade, the rest should be darkish.. insulator white
