Being a retired aircraft tech and recreational pilot I learned to never do anything until oil temp is in the green............I have taken this to just about every engine in my life (of course with no temp gauge you know what I mean). Back in tech school in the '60's they taught nearly 70% of engine wear happens in the first minutes of engine start. Like others I start the motorcycle get the gear on roll it back out of the garage close the door and then on my way and no stalls for me (here in south Texas its hardly ever cold) ............ I don't know what plugs are in it.
