Last report. i changed it because i'm at 12 months. a change in my daily schedule makes it very inconvenient to ride the bike, hence the low miles. this interval used an amsoil oil filter. the amsoil 10W40 was packaged in the bottles labeled as motorcycle oil, dunno if that's different or not.
i think this engine is doing really well. it does seem to shear oils down very quickly, though. the fuel is because of sitting in rush hour traffic at idle for such a long time, i think.
i used schaeffer's racing 20w50 this last time, and am very pleased with it. the cam gear drives are quieter, the engine seems a touch smoother, and the shifting is radically improved. will do a UOA on that oil, too. i noticed this weekend while moving some bottles that the schaeffer's 20w50 says "for v-twin motorcycles" on the front, so i guess they're targeting that oil for harleys, among other things.

blackstone's comments: "... we found no contamination from water, however the lower flashpoint indicates a 1.3% fuel dilution. the viscosity was still in the normal range, and wear was not affected by fuel... the TBN read 12.9..."code:
