the numbers would seem to imply that the interval was too long, but the interval included a 2k road trip in the fall, sitting for a while in the winter, re-jet with new header and pipe and k&n air filter. when drained, oil was probably not at full temp, and the drained oil sat in a tupperware container for couple weeks before the test kit arrived. these factors may have contributed to the fuel and water contamination as suggested by the comments from Blackstone. Blackstone seemed to feel there were no significant problems and that a better sampling proceedure in the future would yield better results.
however, i'm concerned about the iron. i'm also curious as to why the moly and "detergent" numbers should be higher than virgin or averages, unless the fuel and water contamination -and resulting viscosity loss?- may have caused the engine surfaces to start shedding moly coating. -?-
please feel free to comment or advise. cut me some slack tho, i freely admit to knowing little or nothing about the subject. i first used RP a little over 10 years ago when the guys where i took my bmw motorcycle suggested the racing oil after break-in. they'd been using it in their race bikes -ducatis- and had started using it for street bikes with good results. they even started breaking in bikes with RP and seemed pleased with it. when they told me i'd feel an improvement in power i politely nodded my head. then i rode the bike and the engine was quite noticably stronger and smoother. i don't recall exactly but that must have been the Racing 21. i'd like to start using that in this bike, but i'm dubious about the decreased viscosity.
thanks,
Michael
