Don't touch the throttle other wise it'll be a bitch and won't play nice.

I find that the bike starts best when the jetting is just right. The starter jet is pretty lean, so I use a #72 year round. Maybe set the idle a bit higher, too.

This is what I was told when I got my bike by some guys on here. First put your foot on the kick starter. Without kicking it, slowly press it down until it comes to a stopping point...usually about halfway down....when you get here, let the kicker come back to the top. Now give it a real full kick. If it doesn't start, repeat the same way again. Obviously use the choke. Sometimes even when cold the bikes like the hot start depending on where you ride. More tricks are installing a 72 starter jet (the jet by the main jet and pilot jet when you take off your bowl) As for giving it gas, some do some don't...results vary. I usually only give it gas if the fuel has been shut off and the carb bowl has been drained. If this has not happened, then I might give it a twist or two, let it sit for 2 minutes, then kick like I described....sounds like a lot of crap but it takes seconds to do really once you have it down.
Make sure it is at TDC on the COMPRESSION stroke. You will also feel resistance in the kick starter when the piston is approaching TDC on the exhaust stroke. Easiest way to tell if it's the compression stroke is to listen for air rushing into the airbox when you push down on the kickstart lever.
If you flood the bike out riding, this works for me: kick it over a few times with the fuel turned off, decomp lever pulled in and the kill switch pushed in (or ignition off). If you don't have the ignition off, the kickstart will kick back at you!
This technique works with my '86 XR600, might not work as well on your Yamaha...
