do option 1 but if you don't have the service manual get one

Honda Powersports CMX1100D 2021 (helminc.com) $50

there are several things to be observant about ie cover bolt lengths/position and loosening/tightening pattern, dowel pins, oil orifice orientation, tips for sealant application and torque spec for bolts

Honda recommends a sealant equivalent to ThreeBond TB1207B

I had to replace my alternator cover and a couple of other pieces that were damaged in shipment...the dealer ordered the parts and shipped them to me and I put them on. It was an easy job.

I checked my oil level today per the instructions in the manual: warm up the bike for a few minutes, let sit for a few minutes, pull and wipe off the dipstick, insert but don’t screw down the dipstick, take the reading. No oil shown on the dipstick. That’s a lot of missing oil! I got the 600 mile service done a little over a year ago. Yikes! Looks like it’s a bigger problem than I thought. Must be leaking oil as I ride because there was only 1 spot about the size of 2 US quarters side by side on my garage floor. I don’t notice any burning oil so my guess is it’s dribbling out as I’m riding. Sigh.

did you forget to hold the bike upright (level) when checking the oil? you didn't mention that key step in your procedure
