How can you tell if the engine is warm enough to ride on a cold day and how can you minimize this time? Today cycle kept stalling for a long time.

When you turn off the choke, it doesn't stall.

Ride around at low revs with the choke partly on until the above comes to pass.
Make sure your jetting is correct and your plugs are happy.
