              I am using elf campione 10-60 syntetic oil now, instead of 10-50 syntetic and it is excellent. Almost no clunk on up-shift. But it is not JASO approved.

         Ta mate. I know the bike had Motul 3100 last service but not sure if 10-40 was used or the 15-50, probably the latter. I can never remember if the higher the number the thinner or thicker the oil?
