SAE 10w30 is better for lower temp and SAE 20w40 is the opposite better hotter temps.Thanks
No, use exactly what Cummins recommends and nothing else.
SAE 20W40 type SE motor oil for > 40deg F SAE 10W30 type SE motor oil for < 60deg F
According to the Kawasaki site you should use SE class SAE 10W40, 10W50, 20W40 or 20W50 oil for the engine. You use SAE 10W oil for the front fork.
SAE J475 is a specification for thread sizes on tubing. 38 may be a typographic error for a 3/8" thread.
3 litres, 0.79 US Gallons, 6.3 US Pints SAE 10W40, 10W50, 20W40, or 20W50
Use any name brand 100% synthetic oil SAE 20w40.
Yes it is, as long as it also has the designation JASO-AM or AM2, or SAE SF or SG. This specification means that the oil is suitable for motorcycles. There is great difference of opinion among motorcycle drivers as to which kind of mootorcycle oil is best. Don't use ordinary car engine oil in a motorcycle if you can help it and then only for a short period.
You can buy 20w40 oil. Mercursier, Yamalube, Amsoil, and other synthetic oils come in this weight. Or you could just use 10w40 if 20w40 is recommended.

This specification is for hydraulic hoses and the various part numbers describe the construction of the hose including material and how many layers of what kind of reinforcement.
I have heard some derogatory meanings of SAE, "Sexually Assaults Everyone" "Same A******** Everywhere". Unfortunately SAE's real meaning is a secret for them.
