Is it ok to run the bike temporarily in the garage with the inspection cover off just to see if the chain is slapping around after adjustment? Or is that a bad idea?

 

You should not have to do that . Use a coat hanger and bend into a square "s" shape and measure and make adjustment. You a permenment maker to put your distance on the wire and check it Do that and it is correct or wrong. No reason to run it open.

 

I suspect a lot of oil is going to be splashing out of there! Might not be such a good idea.
