so I just got a new bike and I was letting it warm up today I notice that if I blip the throttle it seems to cut out for maybe a half an rpm or so then go back to revving as normal. I raised the idling speed to just over 1.5k and it didn't do that. It has velocity stacks and a K&N air filter. Any ideas? Oh 1/4 turn throttle but I don't that has anything to do with since it changes when I change the rpm's.
