I have never been a long warm up time person outside of when I would ride in rather cold weather.
Mostly I tend to open the fast idle/choke to the first stop, second stop(full on) may be needed for temps 60 and below. Start the motor. When warm outside I will push the fast idle knob in just a bit if idle is already up to perceived high idle. Then put my gear on. Climb on and ride away. Short run to the main road. Pull away and as I reach highway speed I reach down and push the fast idle knob back in to its off position.
Have run 10W-40 oil when new as that was the Triumph recommended product at the time. Have run 20W-50 during the summer before but don't go out of my way to purchase it. Will say that the clatter from the motor top end is a bit less with the heavier oil. But mostly run the currently recommended 10W-50 oil these days.
