I have a 2003 suzuki Vinson 500 when it’s cold start I have to pull it to make it run after it warms up I can use the electric start switch but still lil rough starting sometimes when it’s cold will not start with starting button at all just cranks over but can pull start it can anyone help me out?

 

Afraid not, try taking the plug out, reconnect the lead and lay it against the head, see if you get a spark "on the button" and again with the pull start. My guess is you only get one spark when you use the electric, but a normal, spark every rev, on the pull start. If so, I have no idea how you fix it, but it is quite common and there are lots of posts on here about it, usually Honda 300/350s and Kawasaki 300s though.
