I have a 2002 Whizzer with the threaded dipstick, and I was wondering if the oil level should be checked with the dipstick screwed all the way down or resting on top of the threads. I don't have a manual, but I've had motorcycles where the manual instructs "check with dipstick resting on top of threads". I figured with small engine like that the .5" of threads would probably make a big difference, so I thought I'd ask. Thanks!
