I have trouble starting my bike when it is really cold out 30 and below. I've tried giving it 2 blips, sometimes not, before kicking. I push my kick starter until it hits compression mid way thru the stoke. then pull in the lever, push it about an inch farther, then release to the top, then I try to kick start it. Nothing! I try this for a while, when I smell gas I change the plug. sometimes after a while it will start sometimes it won't. Once it is warm it runs fine and starts on the first kick but I start different. When the compression is felt at the very top I pull in the lever press the starter down about 1/4 the way then release and kick it starts. Is the way I start my bike is incorrect. I didn't have this problem in the warm weather. Is there jetting changes I need to do? any help would be great.
