Gday, just got a Kawasaki quad. I'm picking it's a KLF300 but cant really tell due to the baked on mud and lack of decals. Can anyone tell me where I would find a VIN number or some sort of factory numbers stamped on the frame.
Cheers

Usually on the stem (where the handle bars mount to) or on the front bars of the chassis. Look in from in front of front wheels and there are two tubes that run up should be on one side or other. Engine numbers are a bit harder to find.
