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 🙏

Were you plugs loose, again? And if not, are there any problems other than the idle being rough?
