I recently purchased a CRF50 dirt bike and was going to do an oil change on it. I was talking with a friend and they recommended I take the following steps when I do my first oil change to help "clear things out":
- Drain oil
- Remove spark plug
- Fill Crank case with gasoline through oil filler opening
- Cycle the kickstarter several times
- Drain the gasoline
- Fill with oil
I don't know a lot about cars/motorcycles but I've never heard of anyone doing this and it sounds a little sketchy to me.
Would doing this potentially damage the engine? Does doing this actually help clean the engine?
