A little more info.....
In addition, lots of bikes, including the KLR650, have “wet” clutches, which run in engine oil. Generally, only lighter-viscosity oils such as 5W-20, 5W-30, and 10W-30 are labeled as “energy conserving.” Heavier viscosities such as 5W-40, 5W-50, 10W-40, 15W-40, 15W-50, and 20W-50 oils are not “energy conserving” and can be used for most four-stroke motorcycle engines. Read the container and avoid the “energy conserving” oils. All oils have friction modifiers, but energy conserving oils typically contain more, which may cause clutches to slip under normal use. Most quality non-energy conserving automotive oils should work if your clutch is in good condition.
