Ya guys im back due to #903 post.
Well i have tried the Motul engine oil 15W50 Double Ester and i can tell ya its awesome oil.
1-Gear shift more easly.
2-Better clutch engage.
5-Engine sound i think its crispier, well its!
Last 2 weeks ago with the old oil 15W50 yamalube the clutch ways giving me signs to be changed, with Motul i did not see these sings, maybe in the near future these sings will be back but for how long i have no idea!
Now I love Motul oils.
I'm still using the OEM oil filter, next time i would like to try the Amsoil oil filter with new clutch from Barnett, i hope.
