I have the 1982 Kz750 LTD. I am just using Castrol 10w40 car oil. It must be 10w40 or more, 10w30 and lower viscosity oil has an additive in it the will mess up the clutch. So 10w40 is what i would suggest. But you can buy expensive motorcycle oil, but it is pretty much the same.
The 1981 Kawasaki KZ750 typically requires about 10.5 ounces (or 310 milliliters) of front fork oil per leg. However, it's essential to check the service manual for the specific model variant, as the amount can vary slightly depending on the forks used. Always ensure to use the recommended type and viscosity of fork oil for optimal performance.
any motorcycle oil 10W-40
Use Kawasaki 10W30 motor oil or some good dino oil in it until you get at least 110 hours on it then you can change to synthetic. We prefer the use of 10W30 Mobil 1 synthetic or Royal Purple but ONLY after 110 hours otherwise the engine will nevr break in and the engine will burn oil.
.025 GAP takes NGK BM6 type plug
If it's a 2-stroke engine then you mix the oil with the gasoline something like PJ Lube it should tell you the proper mixture ratio on the gas cap.
regular 87 octane
SAE 5w30 Full Synthetic.
refill the engine with 2.1 quarts of 10W-40 engine oil through the oil filler neck built into the top of the right engine cover
it depends wat type but in general kawasaki are a good brand
There have been many examples of a 350cc two stroke engine made over the years. Kawasaki and Yamaha motorcycles used this type of engine as well as many other manufacturers.
