Always shift down to 1st just before coming to a stop. Always leave some room between you and the vehicle in front of you.
This allows for a fast escape in case you see a cage failing to stop behind you. Just a way to keep you safer on the street and you are assured of the bike being in gear.
You should also lube the shifter linkage. There are 2 little rubber booties on the shift rod from the cases to the shifter lever. Just a shot of chain lube inside the booties will do wonders. A little lube on the speedo cable never hurts either.
I have found that if the tranny won't go into gear just ease out the clutch lever slightly while applying a slight pressure on the shifter and it should slip into gear. Pull in the clutch and wait for the light or whatever. Lube the clutch cable too. Try all of the above and see how it works.
If that doesn't help you may need some adjustments but save those for a later date. Keep to the simple and easy stuff first.
