When I first start my bike it starts but then cuts out. It does it even if I have the choke out. I can usualy get it to idle with a littlle throttle, but sometimes it will cut out when I give it throttle? Before I realized there was a choke (it's my second bike and my 600rr doesn't have one), the bike would cut every time I gave it throttle. Either way after a few attemps(less attemps with the choke out) it will usualy idle. Once I get it to idle, if I snap the throttle it will cut off. Once the bike warms up alittle it runs great. I can shut it off and start it back up with no problems and the throttle response is excellet. So is this normal for this bike or is something wrong? The bike is stock except for the D&D exhaust.
