I know people who have no problem starting at all, unfortunately as I have admitted in the past, my technique is crap so I still have issues, especially when I am tired! My best advice is ti always try to start it when standing on the pegs leaning against a tree or something. I then get the starter to the top of the stroke and give a good firm kick through. With the latest mapping my bike is 2-3 kicks from cold using this method and first kick when warm. I have seen people "snatch at the starter which also seems to work, just not for me. Is your mapping up to date?
