The attempt to remove the cover was a stupid mistake. An attempt to access the space behind the cover where a line (vacuum line ) from the carburetor ran. While replacing the gasket between the carburetor and the intake manifold. It slipped out and I wanted to make sure it didn't connect to anything. Typically I will read and watch some videos beforehand, but I made the mistake thinking all I was removing was a dressing cover. Oops! Ironically, I turned down purchasing the service manual at the HD shop while buying parts to save $60. I think I'll go spend it now.
Good news is the bike still runs great, and I may not have an oil leak either. ( I may have gotten very lucky this time. )
How critical is proper torque? I don't have a torque wrench.
