Referring to the JASO MA spec http://www.oilspecifications.org/articles/JASO_MA_JASO_MB.php I never see any oil that is JASO MA1 rated. Seems all are either MA or MA2 Looking at the spec, MA is split into MA1 and MA2: JASO MA Dynamic Friction Characteristic Index (DFI) >=1.45 and JASO MA1...

I was cruising (Honda Shadow 1100) at about 65 and turned my body to check on a friend riding with me. As I turned forward again my foot came off the peg; my leg dropped and my body lurched forward slightly. This change of position and weight distribution: forward and sideward, along with a...

Hi All, I tried a searches based on filter longevity and deterioration but could not find an answer: I have several vehicles that I properly store for long periods and then drive for short periods (under a month driving and just a 1000 miles or so). Since I never get to the recommended OCI, I...
