"The points system may need to be factored weighted so force and fiction are say worth double points etc. But thats something for discussion to as what would be the best way to combine the metrics into something that best reflects the importance of the differing aspects." Agree but the general "discussion" of how points need to be factored in would push the entire subject into the pattern of the normal oil thread - opinions about which parameters are the most important. Frankly, I have no idea as to which parameter(s) are more important than others as far as operating in the engine. Heck, the "best" parameters would likely change depending on the use of the engine. A bike used for commuting would have a different load factor than one used for racing. An oil that is good for racing might be a poor choice for a bike that is used "normally." One obvious factor comes to mind that is a concern for many folks on these engines - cam/lifter wear. Since there is more inherent cam/lifter wear at low RPM than there is at higher RPM, an oil that provides better protection in the lower RPM ranges would be more critical for a bike that is used daily as opposed to a racing bike that is almost never at low RPM.
