Few months back I acquired a2004 marauder with 46000 miles all stock no mods. I have a very faint valvetrain noise under acceleration. Almost like low octane bad gas or to much timing. I then started to try to remedying the problem. Started by changing spark plugs gas filter cleaning mass airflow sensor. Valve train noise is still present under acceleration. I did notice while changing the spark plugs all four plugs on right bank were wet. All on opposite bank were normal.
Should I change oxygen sensors ? What step should I ltake next ?
