Although I wasn’t able to detect any improvement in performance or economy, the KrankVent did have some merit.  It dried up all my little weeps & seeps.  No more dust accumulation around gasket joints.  No more seepage at the clutch release shaft.  It also seemed to be doing a good job of preventing any accumulation of oil in the catch can.  I’ve been monitoring oil consumption.  It seems to have decreased but I haven’t logged enough miles to tell for sure.  Since there is no adverse impact on performance or economy, I will leave the KrankVent in place.

The earth-friendly breather is also a keeper.  It doesn’t hurt performance.  I can do my little part to keep the environment a little cleaner.

I will continue to monitor the KrankVent and new breather system while I do the long-term test of the 94mm Wiseco flat-top piston.  Maybe over the long haul I may see a slight improvement in my average fuel economy, or a definitive decrease in oil consumption.  We shall see how it works out.
