You're welcome Vic, good to see your progress.
One other thing that came to mind to increase your efficiency would be to drop down in oil viscosity. If you are running a 40 grade oil you could most likely safely drop to a 30 grade oil for less resistance to flow. Synthetic is always a good idea IMO.
It's possible you could even go to a 20 grade synthetic (if you could find a suitable one). Mobil1 makes racing oils in 30 grade, and even if they do contain friction modifiers (not sure) they do also have good/safe levels of ZDDP, unlike current standard auto oils. It's questionable whether modifiers are a significant problem for cycle clutches IMO, but low levels of ZDDP are a better reason to stay away from auto oils in engines without roller lifters.

Last page has the Racing oils. For the most part all oils labled "Racing" have high levels of ZDDP that could eventually damage a catalyst if one is used. That's one of the main reasons they are not recommended for street use. Less detergents may also be a factor.
