Believe the manufacturers of Slick 50 are being sued in USA as they cannot prove conclusively that it works, however I have seen it being put into a V12 Jag engine and watched the idle revs increase as it circulated. What does this prove?, not sure, but the engine was certainly quieter afterwards. As an aside, Castrol make a 15(?)/60 oil for high performance car engines (not reccomended for bike engines with wet clutches). Anybody think this will hold together better at high loads/temperatures??
Am willling to try anything after my recent rocker/cam lobe interface problem
