So I'm pretty new to carb bikes, I used to have a CBR-600rr and decided I wanted a supermoto. I have read the repetitive topics concerning leaving your bike on prime but no answer as to why my bike is ok, everyone seems to have problems. One day I was in the trails and my bike tipped over and wouldn't start, so I set the pet cock to prime and it started fine and I rode/left it sitting like that for 3 weeks because I went to Florida. When I came back I shit myself when I noticed I left it on prime, the bike wouldn't start but was cranking. Eventually I killed the battery trying different choke settings and decided to try to push start it and it started right up. It wasn't idling high like the choke setting was set to but after riding it around for the day it was fine. I let it cool and it started fine. Why does my bike seem ok after what is supposed to be a horrible mess up? Does anyone know the science behind why it wouldn't start at all choked but started fine when I pushed it?
