Stock, they aren't cold blooded. Mine started right up even covered with snow for two days (not my fault, kinda a forced leaving). Today when I went out to start it, I turned the petcock to prime for a second or two. Bam, caught the first spark. Think it really was evaporation issues in the bowls. Have to try the oil in the line. Will goat blood work in the line instead?
However, it never took this long to warm up. I think it's because now it is tuned properly. Before it ran like crap all the time so there really want much of a difference before an after it was warm. I let it warm up for 15 min today and it ran like a striped a$$ ape afterwards. The mods really are an amazing addition to this bike.
