Good tips above. Will add that I always stop my bike in 1st gear and follow "thumb, key, valve" ritual based on my Basic RiderCourse and follow the FINE-C protocol when starting up. Since my bike and most of our bikes have fuel injection and not carburetors it becomes the "thumb, key" ritual and the INE protocol. Full process in case helpful:
Engine stop procedure
1. First gear
2. Kill switch on ("thumb")
3. Ignition off ("key")
4. Kick stand down (some do kick stand to kill engine, e.g. before kill switch, so they always know it is down)
5. Dismount bike to left side (body before hands)
Engine start procedure
1. I typically stay off bike (allows inspecting/walk around; quick warm up while put on gear)
2. Ignition on (I in "INE")
3. Neutral (N in "INE")
4. Kill switch off (E in "INE")
5. Adjust my cold start lever if needed (not sure how many bikes have these; still on some FI bikes)
6. Pull clutch/front brake in, turn on starter, let clutch slowly out, release brake
7. If starting off the bike like I do, I put on my helmet, turn on GoPro's, and put on gloves here
8. Put right hand on front brake, mount bike from left side, level bike (no pressure on kick stand), remove front brake
9. Kick stand up
10. Check my own comfort, do a mental check (am I ready to ride?), idle RPMs, mirrors, surroundings
11. Head onward
This is what I do. Someone is free to criticize/call out something, or endorse/co-sign. Not saying you have to do it this way, just that it works for me. I also tend to do checks of all lights and horn at the beginning of each day I ride.
