took it on my first desert ride with it yeaterday ( have taken it to the track 3 times), twice the kickstarter locked up i couldn't move it at all. i had to put it in gear and rock it back and forth to free it. we had some slower people with us so i was shutting off the bike and starting it a lot ( probably 40 times throughout the day) because i was worried it might overheat if it just let it idle. it was also hard to start a few times, most the time it started on the first kick but a few times i had to kick it upwards of 10 kicks to get it started. the bike seemed to run fine besides that. it has about 25 hrs total on it so i don't think it would be valve clearence issue but this is my first 4 stroke so i don't really know much about them. i did change to a map that was richer on bottom and a little bit retarded ignition, not sure if that's a factor. anyone have this problem before?
